摘要:
The instant invention is directed to a laminate (18) comprising a core layer (24) comprising an oxygen barrier polymer, a heat sealable layer (28) comprising a homogeneous ethylene alpha-olefin copolymer, an outer abuse-resistant polymeric layer (20); and an intermediate layer (22, 26) disposed between the core layer and each of the heat sealable layer and the outer layer, and comprising a polymeric adhesive. In another aspect of the present invention, a package comprises a food product, a pouch containing the food product, the pouch having a longitudinal seal, and the pouch constructed from a laminate comprising a core layer comprising an oxygen barrier polymer, a heat sealable layer comprising a homogeneous ethylene alpha-olefin copolymer, an outer abuse-resistant polymeric layer, and an intermediate layer disposed between the core layer and each of the heat sealable layer, and the outer layer, and comprising a polymeric adhesive.
