Abstract
Abstract A composite integral sheet of wrap material which includes a first layer of absorbent material, a second layer of printable material and an impermeable pigmented polymer layer interposed between the first and second layers. The composite wrap material has a plurality of air pockets formed between at least one of the first or second layers and the polymer layer, by discontinuously bonding the first or second layers to the polymer material. A method of making the composite integral sheet.

The composite material according to claim 1, wherein said second layer has fold retention and a basis weight ranging from 10 to 50 lbs/3,000 sq. ft.
Claim 9
Dependent Claim
24 words
The composite material according to claim 1, wherein said composite material is part of a bag, and said first layer is an inner layer.
Claim 10
Dependent Claim
24 words
The composite material according to claim 1, wherein said composite material is part of a pouch and said first layer is an inner layer.
Claim 11
Dependent Claim
13 words
The composite material according to claim 5, wherein the polymer layer is polyethylene.
Claim 12
Dependent Claim
20 words
