Claims
- 1. A film laminate comprising two or more polymeric films bonded together with an adhesive combination of:
- (a) a styrene-butadiene block copolymer having a monomer parts by weight ratio of from about 1 to 3:3 to 1;
- (b) a cyclopentadiene-styrene resin having a monomer parts by weight ratio of from about 1:2 to 1:4 respectively; and
- (c) a random terpolymer of (1) 1,3-pentadiene, (2) a monocyclic terpene; and (3) alpha methylstyrene, wherein the monomers are in a parts by weight ratio of from about 3-4:3-4:2.5-3.5 respectively; said combination comprising a parts by weight ratio of from about 7-10 of (a), 0.5-1.5 of (b), and 2-4 of (c).
- 2. The laminate of claim 1 wherein at least one film is a polyacrylonitrile film.
- 3. The laminate of claim 2 wherein said polyacrylonitrile film is a homopolymer.
- 4. The laminate of claim 1 wherein at least one film is a polyolefin.
- 5. The laminate of claim 4 wherein said polyolefin is a C.sub.2 -C.sub.8 polymer or copolymer thereof.
- 6. The laminate of claim 5 wherein said polyolefin is a heat-sealable polyolefin.
- 7. The film laminate of claim 1 in which the individual layers range from about 0.1 to about 10 mils in thickness.
- 8. A retortable food pouch fabricated from any of the laminates of claims 2-7 and 1.
