ABSTRACT:
A coextruded multilayer polymeric film for use as a chub film having a core layer of an oxygen barrier material and layers disposed on either side of the core layer comprising a blend of an ethylene alpha-olefin copolymer formed from a polymerization reaction in the presence of a single site catalyst and a tie or adhesive, or alternatively a blend of a tie or adhesive and an ethylene acid copolymer, including a neutralized ethylene acid copolymer such as an ionomer. The film also comprises outer sealant layers comprising a blend of an ethylene alpha-olefin copolymer formed from a polymerization reaction in the presence of a single site catalyst and optionally a compound selected from the group consisting of LLDPE, having a density of between about 0.910 g/cc to about 0.940 g/cc, and an ethylene acid copolymer.
