Title (EN) MULTILAYER FILM
(FR) FILM MULTICOUCHE
(JA) 積層フィルム
Abstract:
(EN) Provided is a multilayer film which has excellent ability to recover oxygen barrier performance that is decreased by a retort treatment. According to one embodiment of the present invention, a multilayer film comprises: a polyamide layer (A) that is formed of a polyamide resin composition (A); a gas barrier layer that is formed of a resin composition containing an ethylene-vinyl alcohol copolymer and an amorphous polyamide; a polyamide layer (B) that is formed of a polyamide resin composition (B); an adhesive layer; and a sealant layer. In this multilayer film, the polyamide layer (A), the gas barrier layer, the polyamide layer (B), the adhesive layer and the sealant layer are sequentially laminated in this order. The polyamide layer (A) and the gas barrier layer are laminated without having an adhesive layer therebetween.
(FR) La présente invention concerne un film multicouche qui présente une excellente capacité à récupérer une performance de barrière à l'oxygène qui est réduite par un traitement en autoclave. Conformément à un mode de réalisation de la présente invention, un film multicouche comprend : une couche de polyamide (A) qui est formée d'une composition de résine polyamide (A) ; une couche barrière contre les gaz qui est formée d'une composition de résine contenant un copolymère d'éthylène et d'alcool vinylique et un polyamide amorphe ; une couche de polyamide (B) qui est formée d'une composition de résine polyamide (B) ; une couche adhésive ; et une couche d'étanchéité. Dans ce film multicouche, la couche de polyamide (A), la couche barrière contre les gaz, la couche de polyamide (B), la couche adhésive et la couche d'étanchéité sont séquentiellement stratifiées dans cet ordre. La couche de polyamide (A) et la couche barrière contre les gaz sont stratifiées sans avoir de couche adhésive entre elles.
(JA) レトルト処理により低下する酸素バリア性の回復能に優れる積層フィルムを提供する。一態様において、ポリアミド樹脂組成物(A)からなるポリアミド層Aと、エチレン-ビニルアルコール共重合体と非晶性ポリアミドとを含む樹脂組成物からなるガスバリア層と、ポリアミド樹脂組成物(B)からなるポリアミド層Bと、接着層と、シーラント層とを含む積層フィルムであって、ポリアミド層A、ガスバリア層、ポリアミド層B、接着層、及びシーラント層は、この順序で積層された積層フィルムに関する。ポリアミド層Aとガスバリア層とは、接着層を介することなく積層されている。
