Zusammenfassung:The present disclosure provides a laminate film for protecting oxygen-sensitive materials. The laminate film includes an ethylene vinyl alcohol polymer layer and an oxygen scavenging layer. The oxygen scavenging layer includes a first polyamide, a second polyamide, and a metal salt catalyst. The first polyamide includes a crystallizable polyamide homopolymer, a crystallizable polyamide copolymer, or a blend thereof. The second polyamide includes an m-xylylene diamine moiety, an isophthalic acid moiety, and a polyamide monomeric diacid precursor moiety.
