摘要：
A multilayer barrier film includes an outer layer comprising a polyamide polymer, a first inner layer including an ethylene vinyl alcohol (EVOH) copolymer, a second inner layer including a polyolefin polymer, a third inner layer including an EVOH copolymer, a fourth inner layer including a polyamide polymer or a polyolefin polymer, and an outer layer including a sealing layer. Rapid post-retort recovery of oxygen barrier is achieved by these films and retort containers made therefrom.
