FLERLAGEDE EMBALLAGEMATERIALER MED GODE EGENSKABER MOD GASGENNEMTRAENGNING

摘要

This invention provides a gas-barrier multilayered packaging material which comprises an outer layer of a composition comprising 55-97 wt% of an EVOH and 45-3 wt% of a polyamide, polyolefin, polyester and/or polycarbonate and an inner layer comprising a hydrophobic thermoplastic resin having a low moisture permeability; and further provides a gas-barrier multilayered packaging material which comprises an outer layer comprising a resin layer having a moisture permeability (measured at 40 DEG C, 90% RH) of at least 40 g/m<2>.day, an intermediate layer of a composition comprising 55 to 97% by weight of an EVOH and 45 to 3% by weight of a polyamide, polyolefin, polyester and polycarbonate and an inner layer comprising a hydrophobic thermoplastic resin layer having a moisture permeability lower than that of the outer layer. Both of them are useful as packaging materials to be used for boil sterilization or retort sterilization.
