FILMS WITH RETORT-SHOCK RECOVERY

FILMS WITH RETORT-SHOCK RECOVERY

A multilayer barrier film for food packaging comprises an outer layer comprising a first polymeric material having a moisture vapor transmission rate (MVTR) of greater than or equal to 10 gram·mil/100 in2/day; a first inner layer adjacent to the outer layer, the first inner layer comprising a first...

description A multilayer barrier film for food packaging comprises an outer layer comprising a first polymeric material having a moisture vapor transmission rate (MVTR) of greater than or equal to 10 gram·mil/100 in2/day; a first inner layer adjacent to the outer layer, the first inner layer comprising a first retortable grade ethylene vinyl alcohol (EVOH) copolymer; a second inner layer adjacent to the first inner layer, the second inner layer comprising a second polymeric material having a moisture vapor transmission rate (MVTR) of greater than or equal to 10 gram·mil/100 in2/day; a third inner layer adjacent to the second inner layer, the third inner layer comprising a second retortable grade EVOH copolymer; and a sealing layer adjacent to the third inner layer; wherein the first polymeric material is not a retortable grade EVOH copolymer. Excellent recovery of oxygen barrier over time is achieved by these films and retortable containers made therefrom.
