Abstract
A drying cloth for transportation receptacles is disclosed, which cloth is composed of multilayer sheet material, the two outer sides of which are, in each case, formed by an absorbant layer. An intermediate layer which is impermeable to moisture is arranged between the absorbent layers. The two absorbent layers and the impermeable intermediate layer are permanently interconnected to form a composite material.

In this regard, it was found that the proportion of condensation water is frequently greater than the proportion of water resulting from thawing.
The object of the invention is to provide a drying cloth for transportation receptacles and, in particular, for receptacles which are intended for the transportation of cooled, frozen and deep-frozen goods, with the aid of which drying cloth it is prevented that condensation water and water resulting from thawing can converge.
According to the invention, there is provided a drying cloth for use in the interior of a transportation receptacle for the transportation of frozen goods, wherein said drying cloth separately absorbs condensation water in said receptacle interior and water from thawing of said goods, said drying cloth comprised of two outer layers formed of absorbent material with a water impermeable intermediate layer between said outer layers, said outer and intermediate layers are permanently interconnected to form a composite material, wherein said condensation water absorption occurs in one of said outer layers and said thawed water absorption occurs in the other of said outer layers and said intermediate layer maintains separation between said condensation water and said thawed water, ,~
- 3a ~ 203075 n wherein said two outer layers are formed of cellulose fabric having a weight per unit area of 100 g/m2 and said intermediate layer is a plastic sheet having a weight per unit area of 50 g/m2.
The multilayer sheet material according to the invention can be placed in a position as a lining in a receptacle for cooled or frozen goods, it being immaterial as to which side of the sheet material faces outwards and which side faces inwards, since the outer absorbent layers or coats thereof are preferably designed to be identical and have the same thickness and, therefore, identical absorbency and absorptive capacity. By means of this drying cloth, both the condensation water which is present on the receptacle '-~
