Claims
- 1. A multiple layer film, comprising:
- (a) a first layer, the composition of said first layer being selected from the group consisting of polyesters, copolyesters, polycarbonates, and polyether block amide copolymers;
- (b) a second sealant layer comprising (i) a first component of a polypropylene and (ii) a second component of a styrene ethylene butylene styrene copolymer; and
- (c) a third adhesive layer adhering said first layer to said second layer, said third layer being positioned between said first and second layers, and in surface-to-surface contact with said first layer, the composition of said third adhesive layer comprising a carboxy modified propylene.
- 2. A multiple layer film comprising:
- (a) a first layer, the composition of said first layer being selected from the group consisting of polyesters and copolyesters;
- (b) a second sealant layer; and
- (c) a third adhesive layer adhering said first layer to said second layer, said third layer being positioned between said first and second layers, and in surface-to-surface contact with said first layer, the composition of said third adhesive layer comprising a carboxy modified polypropylene.
- 3. A multiple layer film as in claim 2 wherein said first layer comprises a glycol modified cyclohexanedimethanolcyclohexanedicarboxylate, a copolyester.
- 4. A multiple layer film as in claim 1 wherein the composition of said second sealant layer comprises a combination of about 40% by weight to about 90% by weight of said polypropylene and about 60% by weight to about 10% by weight of said styrene ethylene butylene styrene copolymer.
