Abstract

A flexible package having an integrated reclose strip, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines The reclose strip comprises a length of tacky two-sided adhesive tape The apparatus for applying a reclose strip is incorporated into the mechanism which supplies the continuous sheet of packaging material to the vertical form, fill, and seal machine The invention involves producing a pillow pouch or vertical stand-up pouch having an integrated reclose strip from a single sheet of packaging film In one aspect, the reclose strip comprises a release liner on one side after package formation. In one aspect, the reclose strip comprises no release liner and is attached along the longitudinal axis of the sheet of packaging material such that the reclose strip is disposed in a channel or recess in the fill tube.

Claims

-22-AMENDED CLAIMS received by the International Bureau on 05 October 2007 (05.10.07).
1. A flexible package formed by a form, fill, and seal packaging machine from a sheet of composite polymer film, said package comprising after formation: a single sheet, composite film body, said film comprising a graphics layer; two vertical transverse seals on opposite vertical edges of said package; and a rcclose strip comprising tacky two-sided adhesive tape adhered Io said package between said two vertical transverse seals.
2. The flexible package of claim 1 further comprising a gusset at the bottom of said package, said gusset being substantially perpendicular to said vertical transverse seals.
3. The flexible package of claim 1 further comprising a score line adjacent said reclose strip.
4. The flexible package of claim 1 wherein a first side of said reclose strip comprises a first peel force and said second side of said tape comprises a second peel force, wherein further said first peel force is greater than said second peel force.
5. The flexible package of claim 1 wherein said rcclose strip further comprises a release liner.
6. The flexible package of claim 1 wherein said reclose strip comprises no release liner.
7. Λn improved vertical form, fill, and seal machine for making rcclosable package, said improvement comprising a supply mechanism for dispensing a reclose strip comprising lacky iwo-sided adhesive tape to a packaging film above said forming tube.
8. The improved machine of claim 7 further comprising a recessed forming tube.
9. The apparatus of claim 8 further comprising a pinching mechanism to apply pressure to the reclose strip and the packaging film, wherein said pinching mechanism is below said recessed forming tube.
10. The apparatus of claim 7 further comprising: two forming plates attached to and extending below said forming tube; at least one tension bar attached to and extending below said forming tube at a location approximately opposite from said forming plates; and at least one stationary tucker bar positioned between said forming plates.
-24-
1 1. A method for making a flexible reclosable stand-up package on a vertical form, fill, and seal machine, said method comprising the steps of: a) advancing a continuous sheet of packaging film towards said vertical form, fill, and seal machine; b) attaching a length of rcclosc strip comprising tacky two-sided adhesive tape to a surface of said advancing sheet of packaging film along the longitudinal axis of said sheet of packaging film; c) feeding said packaging film into said vertical form, fill, and seal; d) forming said packaging film into a tube on said vertical form, till, and seal machine and forming a longitudinal seal, wherein said side of packaging film having said reclose strip comprising tacky two-sided adhesive tape attached thereto is situated on the interior of said tube; e) forming a first traverse seal on said tube, said first traverse seal sealing all layers of said lube together; f) dropping a product into a partially formed package created by steps a) through e); g) forming a second traverse seal on said tube, said second traverse seal scaling all layers of said tube together; and h) severing said package from said tube at said second traverse seal.
12. The method of claim 1 1 , wherein said reclose strip further comprises a first side having a first peel sLrength and a second said having a second peel strength, wherein said first and second peel strengths are different.
13. The method of clai m i l, wherein said reclose strip comprises a release liner. -25-
14. The method of claim 1 1 wherein said machine at step c) comprises a recessed fill tube,
such thai said reclose strip is aligned with said recessed portion ai step d).
15. The method of claim 14 further comprising the step of removing a release liner from said reclose strip after step b).
16. The method of claim 15 further comprising the step of adhering inner film walls together with a pinching mechanism prior to step f) of dropping product into said partially formed package.
17. The method of claim 1 1 further comprising the step of forming a vertical crease in said tube of packaging film prior to sealing said lube transversely.
