Abstract
Description
- The present invention generally concerns flexible bags, bag arrangements or pouches that include a gas vent or gas filter arrangement. In particular, the invention concerns an arrangement which in operation: can be closed and sealed about an object or objects contained within the bag arrangement; and, from which certain types of gas build-up in the pouch arrangement interior can be readily released, in a preferred manner. Preferred applications concern such arrangements including means for opening and resealing, during use. The invention also concerns methods for preparing such bag arrangements, and methods of use.
- A variety of items are marketed enclosed within flexible bags or bag constructions. Among other things, such constructions can generally operate to: protect the enclosed item(s); retain a plurality of items in close association with one another; facilitate storage and handling; facilitate access to a portion of a stored quantity; and/or to inhibit contamination (and maintain freshness) of stored material. A variety of bag designs have been used, for such purposes.
- In some instances, items stored within the bag construction are not completely stable, after the construction is sealed closed. For example, at a food processing/packaging plant materials such as coffee beans may be packaged (sealed) within such bag constructions, while hot. As materials such as coffee beans cool, gases are given off. These gases will expand the flexible bag construction taut, and eventually rupture it, unless vented.
- To maintain integrity of the bag construction under such circumstances, vented bag arrangements have been developed. A frequently used general type of construction is one which involves an aperture or pore in a side wall of the bag construction, which is covered by a porous filter. As gas pressures build up within the sealed bag arrangement, the gases can pass outwardly through the vented pore and filter, to reestablish equilibrium of pressure between the interior and exterior of the bag. One commercially available filter for such use is the Bosch filter available from Robert Bosch Corporation. This filter arrangement generally comprises a piece of porous polymer material including portions having adhesive thereon, selectively positionable over a pore in the bag.
- Conventional vented flexible bag arrangements for containing materials such as coffee have not been completely satisfactory in function. Reasons for this include the following: such constructions have not, in general, been conveniently constructed for ease of opening and resealing; the position of the vent or filter has not been completely desirable for maintenance of integrity during shelf life and use; and, the position of gas vents or filters in such arrangements have not been fully satisfactory with respect to potential interference with the operation thereof by material received within the bag, during use.
- A better understanding of conventional arrangements can be obtained from consideration of the conventional arrangement illustrated in FIGS. 1 and 2. In FIG. 1 there is depicted, in perspective, a conventional, vented, flexible bag arrangement1 having material 2 (such as coffee beans 3) stored therein. Arrangement 1 has first and second closed
ends opposite sides End 6 is preferably relatively permanently closed, by staples, adhesive or the like.End 5 is also closed (at the packaging plant) by means such as staples and/or adhesive; however it is opened (by the consumer or user) for access to an interior, to removecoffee 3 therefrom. In use,end 5 is reclosed by rolling that end of the bag up, and clipping, clamping, taping or otherwise securing the rolled up end in a tightly coiled configuration. As arrangement 1 is further depleted of its contents, during further use,end 5 is further rolled and compressed towardend 6. Reasons why this type of closure has been preferred include the fact that to maintainmaterial 2 within arrangement 1 as fresh as reasonably possible, it is generally desirable to leave as little air in the arrangement 1, during storage, as easily manageable. - Still referring to FIG. 1, on an
upper surface 10 of arrangement 1 a vent system orarrangement 15 is positioned.Vent arrangement 15 comprises a porous polymer filter arrangement ormember 16 positioned over apore 17.Pore 17 extends throughsurface 10, into fluid flow communication with aninterior 18 of arrangement 1. Gas pressure build-up within arrangement 1, then, is vented by passage of the gases throughporous filter member 16. Thefilter member 16 is selected, however, so that solid particles and the like do not pass there through. Thus, the contents of the bag do not leak outwardly. Also, preferablymember 16 is selected so that it acts as a barrier to microorganism and moisture passage into the bag 1, to maintain freshness. - In a typical use, arrangement1 is constructed with one open end (for example end 5) and is filled with
material 2 to be stored, whilematerial 2 is still in a hot state. The open end (end 5 in the example) is then sealed closed, and as the material cools, gases are given off. The gases build up pressure within arrangement 1 and are vented throughpore 17 andfilter member 16. - When the arrangement is ultimately obtained by a consumer,
end 5 is opened, as necessary, for removal of material stored therein. As described above,end 5 is reclosed by collapsing, folding or rolling it towardend 6, and is maintained closed by means such as a retainer, clamp or tape. This practice is repeated, until the contents are completely used. - Typical operation of the arrangement1 as just described, involves at least two potential problems. First, as
end 5 is reopened and reclosed during use by the consumer, eventually the consumer will collapse or rollend 5 past ventedarrangement 15. This poses little problem with respect to the required operation ofvent arrangement 15, since its purpose will generally have been served prior to the consumer even obtaining the arrangement. However, a potential problem is nevertheless presented. In particular,vent arrangement 15 represents a portion of the overall construction 1 in which, as a result of thepore 17 and thefilter member 16, a site of potential failure is presented. For example, in general, conventional arrangements utilized as afilter member 16, are not as flexible as materials used as the side walls,i.e. surface 10, of typical bag constructions 1. If thevent arrangement 15 resists coiling or collapse during the folding/rollingprocess involving end 5, thevent arrangement 15 or the construction 1 may tear or rupture, leading to a failure in the integrity of a side wall of arrangement 1. Thus, inconvenient spills, etc., may occur. Further, loss of freshness, due to loss of integrity of the closed system, may result. Similar problems would occur if instead of rapture, separation of thefilter member 16 from the construction 1 occurred. - Another potential problem is presented from the location of
arrangement 15. In particular, its position is such that when arrangement 1 is filled during packaging, solid material is present within arrangement 1, directlyadjacent vent arrangement 15. Such solid material may interfere with free flow of gases through thevent arrangement 15. For example, prior to cooling and releasing of gases, small particles (i.e. dust) within thestored material 2 may blockpore 17 and/orfilter 16, so that when the gases are released from the stored material, they are not as readily vented from the bag arrangement 1. - Another potential problem with the arrangement of FIG. 1 is that it is not especially convenient for the consumer to use, from the point of view of opening and reclosing. For some consumers it may be inconvenient to perform the ritual of rolling the
end 5 of arrangement 1, between uses, and finding a method of maintaining same closed, for example, through use of tape or clamps. While some conventional arrangements include wires therein (or tape thereon) to facilitate the process, these may be relatively expensive to provide and/or inconvenient to use. Further, they may represent yet another site of potential failure in the construction or maintenance of closure. - To further facilitate understanding of the arrangement of FIG. 1, attention is directed to FIG. 2. FIG. 2 is a perspective view of a
panel 20 having avent arrangement 21 therein, from which an arrangement such as that of FIG. 1 can be formed. That is, arrangement 1 of FIG. 1 is formed from a single panel, and thus provides for a single seam. Formation of the seam will be understood by reference to FIG. 2, whereinpanel 20 is shown folded to formupper surface 25opposite side gussets back panels back panels example end 30, prior to filling with material. After filling with material, theopposite end 31 is then closed, the result being an arrangement similar to that shown in FIG. 1. In some instances thefilter member 33 of thevent arrangement 21 is applied after formation of the bag, rather than before. - According to the principles of the present invention, a pouch arrangement is provided which comprises: first and second opposed panel sections; a base gusset member; and, a gas filter arrangement oriented in one of the panel sections. The gusset member is preferably oriented between the panel sections, along ends thereof, to form a base by which the arrangement can be stood up during use. Since the arrangement can be readily stood up during filling, venting and use, it can be filled such that the solid material does not reach a level of position of the gas filter arrangement. In this manner interruption of operation of the gas filter arrangement, by material stored within the bag during filling, can be inhibited if desired. As will be seen from the detailed descriptions, the two panel arrangement facilitates this, by providing, through use of an upper transverse seal or seam, for a slanted side wall portion, which tends to lift and project the vent arrangement, when appropriately positioned, out of contact with solid material stored therein.
- Preferably the arrangement is provided with closure means extending thereacross, provided with means for selective opening and reclosing of the pouch construction. A preferred such closure means is a rib and trough closure arrangement, such as sold under the trademark Ziploc® by Dow or ZipPak by Mini-Grip, Inc. In this manner, opening and reclosing the bag construction, for access to material therein, is facilitated. Further, it is facilitated in a manner which does not involve rolling or otherwise manipulating the material of the flexible bag in the region of the vent arrangement. Thus, potential failure in a manner similar to that of conventional systems is inhibited to advantage.
- The preferred gas filter arrangement comprises a pore in one of the panel sections, with a filter arrangement such as porous filter member mounted thereover. Preferably the pore is relatively small in diameter, i.e. no greater than about 2.0 mm, more preferably no more than about 1.0 mm.
- In preferred embodiments, the orientation of the gas filter arrangement pore, relative to the rib and trough closure arrangement, is selected to facilitate maintenance of the gas filter arrangement relatively clear of solid material when the material is poured into the bag construction during packaging and the bag construction is stood upright. In general, this is done by maintaining the pore arrangement within a preferred distance of the rib and trough closure system definable as a percentage of the distance between the rib and trough closure arrangement and the base gusset (or bag end adjacent the base gusset). Preferably, the pore is positioned within about 2% to about 30% of the distance between the rib and trough closure arrangement and the bottom gusset or panel end edges. More preferably, it is positioned within about 4 to 17% of that distance. In a typical preferred application it will be positioned about 2.5 to 5.0 cm from the rib and trough closure arrangement.
- For the most preferred arrangements, the rib and trough closure arrangement is positioned a selected distance of at least 0.75 cm from an end of the bag arrangement. As a result, room is left over for a seal such as a heat seal across an open end of the bag, during packaging. Further, a tab arrangement is formed which can be cut or removed from the bag by the consumer, during use. Removal of this tab arrangement is facilitated, by selected positioning of tear notches in the bag arrangement.
- The principles described herein also concern preferred methods for creating vented bag arrangements. One such preferred method comprises providing a continuous full web of panel sections of material; splitting the full web into first and second continuous half webs of panel section material; punching a pore into one of the two half webs of panel section material; forming a pouch arrangement from the first and second half webs, the pouch arrangement having opposed front and back panels, the front panel having the pore therein; and, applying a filter arrangement over the pore. Preferably the method includes positioning a base gusset between the front and back panels in a preferred orientation for operation in the completed arrangement. Most preferably, a rib and trough closure arrangement is also operably oriented between the front and back panels, during construction. In general, the method will also include steps of providing appropriate seals between adjoining members; and, trimming as necessary to provide the pouch.
- The method described above lends itself well toward mass production techniques, utilizing continuous webs wherein a plurality of pores are positioned into one of the two half webs, and a plurality of pouch arrangements, each having one pore therein, are formed. In some applications a wide web can be provided in a manner forming two adjacent lines of pouches.
- It will be understood that in alternate applications, the methods may involve forming the two panels from separate webs of material, rather than a single continuous web split into two half webs. In general, a decision about which method to utilize will depend in part upon availability of webs and the design of selected machinery for manufacture.
- The pore may be created in a variety of manners. One convenient manner is through utilization of a punch or the like. The punch may be applied with sufficient force to create a small tear or rupture in the bag, of a size appropriate for forming a vent arrangement.
- The methods described are advantageous, as the pore is applied in one of the panels before the two panel construction is formed. Thus, there is no risk of punching the pore completely through the bag or pouch arrangement.
- The drawings constitute part of the specification and disclose details concerning preferred constructions and/or methods according to the invention. It will be understood that in some instances, relative material thicknesses or component sizes may be shown exaggerated, to facilitate an understanding of the invention.

- In FIG. 3 a preferred bag or
pouch arrangement 50 according to the present invention is depicted.Pouch arrangement 50 is rectangular, although other arrangements may be utilized.Arrangement 50 has first and second, opposite, ends 52 and 53; and, first and second oppositeside edge portions 54 and 55. - The arrangement of FIG. 3 is formed from first and second, opposed, panel sections,60 and 61. Each of
sections edges side edge 54 and 55 of theoverall arrangement 50.Panel sections side edge portions 54 and 55. For the preferred arrangement shown in FIG. 3, this is by means ofseals 65 and 66, respectively.Seals 65 and 66 extend alongside edge portions 54 and 55 respectively, betweenend 52 and points 70 and 71, respectively. For preferred embodiments the panel sections are formed from flexible, heat-sealable material; and seals 65 and 66 are heat seals. - As previously explained, each of
sections end edge 53 of theoverall arrangement 50. In this portion of the arrangement 50 (i.e. near edge 53), a base gusset orbottom gusset 75 is positioned.Gusset 75 includes twoside panels hinge fold line 78.Gusset member panel 76 is secured topanel section 60 by means such as heat sealing, preferably defining a curved line as shown at 79, FIGS. 3 and 4, the sealing being shown inregion 80; and,gusset panel 77 is secured topanel section 61 by similar means (curved line 80 a, FIG. 4). Referring to FIG. 5, when thepouch 50 is filled and expanded, the bottomgusset side panels base 81. - For the preferred arrangement illustrated in FIG. 3, at
base corner regions panel sections gusset panels corners panel sections arrangement 50 is filled, FIGS. 4 and 5. - As a result of the two panel section (60, 61) and base gusset (75) arrangement, thus far described,
bag construction 50 is oriented such that when filled or partially filled, thebase gusset 75 can expand in a manner supporting the arrangement in a standing or upright position. This is illustrated, for example, in FIGS. 4 and 5, whereinarrangement 50 is depicted expanded as it would be when filled with material. Such two panel section arrangements, with edge seals and a bottom gusset, as thus far described, are known. -
Pouch arrangement 50 is provided with closure means 90 adapted (i.e. constructed and arranged) for selective opening and closing of the arrangement, for access to material received therein. For the preferred embodiment illustrated in FIGS. 3, 4 and 5, the closure means 90 comprises a rib andtrough closure arrangement 100. The rib andtrough arrangement 100 includes (FIG. 6) anelongate rib member 101 releasably securable within aelongate trough member 102. A variety of specific constructions may be utilized, including those available under the trademark Ziploc® from Dow and ZipPak from Mini-Grip, Inc. - In general, the rib and
trough closure arrangement 100 extends acrosspouch arrangement 50, i.e. in FIG. 3 substantially between side edges 54 and 55, or alternatively stated between edge seams 65 and 66. It will be understood that, in general, theinterior 110 ofarrangement 50, FIG. 5, is generally defined betweenclosure arrangement 100 and bottom gusset orbase gusset 75. Rib andtrough closure arrangement 100 facilitates access to the interior 110 by the consumer, in use. Because it (the closure means) is readily resealable, it provides a convenient means for maintainingmaterial 111 stored withinarrangement 50 in a relatively fresh state. Sincepanels arrangement 100, to vent excess air from within thearrangement 50. This, it will be understood, can be readily accomplished without the inconvenience of rollingedge 52 towardbottom gusset 75, i.e.end 53. - Preferably, the closure means, i.e. rib and
trough closure arrangement 100, is oriented spaced fromend 52, FIG. 3, a sufficient amount to allow for positioning of an end seal, for example a heat seal, atend 52 during commercial packaging, see forexample end seal 115, FIGS. 4 and 5. A reason for this is that such an end seam, for example a heat seal, is preferably applied during factory packaging to facilitate retention of a secure seal aboutenclosed material 111. It will be understood that the rib andtrough closure arrangement 100 is convenient for use by the consumer, but does not provide a relatively permanent seal such as is often preferred for commercial packing, storage and shipping operations. Preferably,arrangement 100 is positioned at least 0.75 cm fromend 52, more preferably at least about 1.5 cm therefrom. Such an arrangement readily accommodates aconventional end seal 115 formed as a heat seal, which typically has a width of at least about 0.5 cm. - Referring to FIG. 3, as a result of the spacing from
end 52, atab region 120 is formed which is to be cut or torn open by the consumer, when initial access to theinterior 110 ofarrangement 50 is desired. For the preferred arrangement, opening is facilitated by positioningtear notches arrangement 50, betweenclosure arrangement 100 and end 52, in a manner developing apreferred tear line 125 across arrangement 50 (preferably parallel to the rib and trough closure arrangement 100) for opening. The tear notches preferably are completely contained within edge seals 65 and 66, to facilitate integrity of closure. - Referring to FIG. 3,
arrangement 50 includes avent arrangement 130 on onepanel section 60 thereof. Preferablyarrangement 130 comprises means whereby gas pressure that may build withininterior 110 ofbag arrangement 50, when sealed closed, can be equilibrated with ambient pressure. More specifically, should the gas pressure withinseal arrangement 50 exceed ambient, or tend to exceed ambient, gas will preferably be vented throughvent arrangement 130, re-equilibrating the system. Preferably, arrangement 130 (FIG. 7) comprises apore 131 covered by a gas permeable filter arrangement preferably comprisingfilter member 132. A preferred such arrangement comprises a pore having a size less than about 2.0 mm, preferably less than about 1.0 mm, covered by a porous polymeric member. Preferably the filter member orarrangement 132 includes acentral recess 133 and an outeradhesive periphery 134, FIG. 7. Appropriate porous members are sold as Bosch filters, by Fres-Co System USA, Inc. Such filters generally contain a circular piece of polymer material having an outer periphery provided with adhesive, for retention about apore 131. - Referring to FIGS. 4 and 5, certain advantages from the present construction will be understood. Referring specifically to FIG. 5, it will be understood that
arrangement 130 can be readily positioned above anupper level 145 ofmaterial 111 contained withininterior 110 during the venting process. Thus, it is not likely thatmaterial 111 will directly interfere with operation ofarrangement 130. This is facilitated by the fact thatarrangement 130 is provided with abase gusset 75 upon which it stands during storage. Thus, during packaging,material 145 can be poured intoarrangement 50 throughend 52, up to a level belowarrangement 130, if desired. - To facilitate operation, preferably vent
arrangement 130 is positioned in aportion 150 ofpanel section 60 which slants substantially inwardly towardopposite section 61, whenarrangement 50 is filled or partially filled. This is accomplished, by positioningvent arrangement 130 substantially near the upper sealing arrangement, for example closure means 100 (or end seam 115) and is facilitated by the two panel (i.e. front and back panel) construction. The preferred, precise, positioning will depend, primarily, upon the overall length, i.e. height, ofarrangement 50, FIG. 5. In general, thevent arrangement 130 will be appropriately positioned if located a distance from rib andtrough closure arrangement 100 corresponding to about 2.0 to 30.0% of the distance of rib andtrough closure arrangement 100 fromend 53 orbottom gusset 75, FIG. 5; i.e. from afurthermost point 145 andseal 79, FIG. 3. More preferably,vent arrangement 130 is located within about 4.0 to 17% of that distance. In typical preferred applications thepore 131 should be positioned about 2.5 to 5.0 cm from the rib and trough closure arrangement. Such positioning assures that it will be inupper region 150, preferably abovelevel 145 if desired. Such a positioning facilitates operation without substantial waste ofinterior volume 110, sincearrangement 130 is positioned in a portion whereatpanels arrangement 130 directed upwardly, abovematerial 111. - While a variety of means may be utilized to prepare arrangements according to FIGS.3-5, herein a preferred, convenient, method is described. The general steps are illustrated in the flow diagram of FIG. 8.
- According to the method, two webs of material, each preferably being of approximately the same width and preferably continuous, are provided, at200. A pore is punched in one web, at 201. The two webs will be brought together, in opposition to one another at 204. It is these two webs, when cut in sections, that will form opposite panels, for
example panels - Again, before the two webs are brought together, a pore is provided in one of the webs,201. The pore is positioned such that it will be appropriately oriented as the venting pore, i.e.
pore 131, FIG. 3, of the completed product. The pore may be formed in a variety of means, including by means of a punch apparatus. - In the
next step 204, the two webs are brought together in opposition, ultimately to comprisepanel sections - In a later step of the process (at210), the continuous composite which comprises: a first web having a hole punched therein; a second web opposed to the first web; and, a continuous gusset web and a continuous closure arrangement, both of which are positioned between the two panel webs, is cut, trimmed and sealed, preferably by heat sealing, into a pouch arrangement corresponding to
arrangement 50, with one open end, for example corresponding to end 52, FIG. 3. Following this step, for preferred applications at 211 a porous filter member corresponding to filtermember 132, FIG. 3, is applied over the pore. Of course, the filter member could be applied before trimming and sealing, if desired. - It will be understood that continuous, mass, manufacture of articles (pouches) from a pair of continuous webs can be facilitated by punching a plurality of holes into one of the two webs, the holes being oriented and spaced apart appropriately.
- In some applications it may be desirable to form the two webs (to be brought together) from a single roll or web of material. This can be done, for example, by providing a primary web which is split in half, longitudinally, to form two half webs. These webs can then be utilized as the two webs of the schematic illustrated in FIG. 8.
- Schematics illustrating the principles of FIG. 6, are shown in FIGS.9-12. Referring to FIG. 9, a single web of
material 270 is shown split in half, longitudinally, atline 271, to form first and secondhalf webs webs 273 is pierced or ruptured, i.e. a pore is formed therein which will eventually become the pore of a vent arrangement in a bag formed therefrom. This is done before the webs are brought together, to facilitate formation of the pore without rupturing completely through both panel sections of the arrangement, i.e. through both webs. In FIG. 9, a step of forming the pore is illustrated atstation 279. - For the system shown in FIG. 9, the
webs tab section 120, FIG. 3, and during a later cutting and trimming process, they are cut apart. Since two pouches are formed at any given time atstation 279 two pores are provided atstation 279, by means ofarrangements - At station277, whereat
webs continuous web 283 of base gusset material 2839 is shown fed in at 284; and, acontinuous strip 286 of rib and trough closure material is shown fed in atpoint 287. At station 277 all four are oriented, for formation of a pouch arrangement such asarrangement 50, FIG. 3. That is, an overallcontinuous composite 290 is formed. - As previously mentioned, for the preferred process, at station277 two longitudinally spaced pouches are formed. Thus, the composite formed at station 277 comprises a continuous web having a center longitudinal line dividing it into a first and second half, each half comprising the structures of pouches according to the present invention. Thus, at station 277 a second web 292 of gusset material is fed into the arrangement; and, a
second web 293 of rib and trough closure material is also fed into the station 277. - The general configuration of the composite of web material leaving station277 will generally be understood, by reference to the overall continuous composite as it appears after heat sealing but prior to trimming, this is shown in FIG. 11, discussed below.
- Still referring to FIG. 9, at300 the continuous web composite 290 passes through
heat sealing arrangements 301, to render appropriate heat sealing in the construction. The general appearance of theweb 305 as it leaves the heat sealing apparatus will be understood by reference toregion 310 which shows the web construction from a top plan view. In particular, attention is directed to FIG. 10 which showsregion 310 in detail. -
Web construction 310 is preferably continuous in a direction indicated byarrows center line 315 into first and secondopposite halves halves - The
continuous strip 310 is advanced to cutting and trimming station 340 (FIG. 9) whereat it is split in half and each half is trimmed into individual pouches. - It will be understood that the base gusset and rib and trough closure arrangement of one half of
construction 310 resulted fromgusset feed 283 and rib andtrough closure feed 286; and, the gusset and rib and trough closure arrangement of the other half resulted from theother feeds 292 and 293, respectively. - In FIG. 11, a next step of positioning a
filter 350 over apore 351 is shown. Preferably, this step will be conducted after the pouch arrangement has been sectioned from the continuous strip. Pore 351, it will be recalled, resulted from punching atstation 279. - A variety of means may be utilized to create pores in one of the continuous webs. In FIG. 12, a preferred process is shown wherein a
web 405 in which a pore is to be punched, is tightly stretched betweenstations web 405 is stretched taut, ablunt punch 408 or the like is struck thereagainst, sufficiently rupturingweb 405 to form a small pore therein. Thepunch 408 may correspond toapparatus - A preferred method of use of the arrangement shown in FIGS.3-5 will be readily understood by examination of FIG. 5. Preferably, the bag, having been formed for example by the process described with respect to FIGS. 9-12, is filled or partially filled with material to be stored therein, with the bag being oriented substantially vertically as shown in FIG. 5, i.e. with
upper end 52 at a highest location. Preferably the pouch arrangement is filled such that anupper level 145 of thematerial 111 is belowvent arrangement 130. The bag arrangement can then be sealed alongedge 52, for example, by heat sealing methods. Also preferably at the same time, or as appropriate just before or after heat sealing,closure arrangement 100 is also sealed, for convenience. - It will be understood that the arrangement of FIG. 5 is particularly convenient for display in a store, or stores. This results from the fact that the
arrangement 50 includes abase gusset 75, so it can be supported substantially vertically. Thus, advertising indicia or the like on either or both ofpanels - Pouch arrangements according to the present invention may be manufactured from a variety of materials. It is particularly advantageous, however, that they be constructed from relatively thin strong material such as polyester film, particularly metallized polyester film. Preferred embodiments which are particularly useful, and include advantages according to the present invention, may be constructed wherein the first and second panel portions comprise first and second sheets of metallized polyester polyolefin laminate film, each having a thickness within a range of about 1.5-6.0 mil, more preferably about 3.0-5.0 mil. Similar material may be utilized for the base gusset. Preferably, heat sealable metallized polyester/polyolefin film is utilized, so that the means of securing the panel portions to one another, securing the closure means to the panel portions, and securing the gusset in place, is by heat seals without the need for additional adhesive.
- One preferred metallized polyester film material utilizable to form bag arrangements according to the present invention is available from Flexicon, Inc., under the designation Laminated Metallized Polyester. It comprises a 48 gauge ICI #443 metallized polyethylene material metallized to 2.0-4.0% light transmission. Another material that may be utilized is heat sealable polyester film number 48, a non-metallized film available from 3M under the trademark SCOTCHPACK®. Such material has a tensile strength of about 9 lb/inch width, 100% elongation, burst strength about 50 lb/inch2, edge tear strength about 1,000 grams and Elmendorf tear strength of 80+ grams. The suggested heat seal conditions for such an arrangement are about 300-400° F. for 0.2-2.0 seconds at 20-60 psi.
- It is also noted that Totani Giken Kegyo Co., Ltd. of Kyoto, Japan, produces a pouch making machine under the designation BH-600S which can be utilized to form two panel pouches having a base gusset. Such an apparatus can be modified to provide for pouch arrangements according to the present invention, including closure arrangements and vent pores therein.
- Pouch arrangements according to the present invention may be provided with a variety of outer dimensions, depending upon the intended use. A particular convenient arrangement has
dimensions 26 cm by 16.5 cm. - It is to be understood that while certain embodiments of the present invention have been illustrated and described, it is not to be limited to specific forms or arrangements herein described and shown.
