Title (EN) LAMINATED STRETCHED POLYAMIDE FILM
(FR) FILM POLYAMIDE ÉTIRÉ STRATIFIÉ
(JA) 積層延伸ポリアミドフィルム
Abstract:
(EN) [Problem] To provide a laminated stretched polyamide film having excellent water-resistant adhesiveness (water-resistant laminate strength), shock resistance, and pinhole resistance. [Solution] This laminated stretched polyamide film in which a readily-adhesive layer (layer B) is laminated on at least one side of a substrate layer (layer A), wherein the layer A contains 70 mass% or more of a polyamide 6, and the layer B contains a polyamide 6 copolymer, in which a proportion of 60-100 mass% of a copolymerization component is 3-35 mass%, and 0-40 mass% of a polyamide 6.
(FR) L'invention vise à procurer un film polyamide étiré stratifié ayant une excellente adhérence résistant à l'eau (force de stratification résistant à l'eau), une excellente résistance aux chocs et une excellente résistance aux trous d'épingle. A cet effet, l'invention porte sur un film polyamide étiré stratifié, dans lequel film une couche adhérant facilement (couche B) est stratifiée sur au moins un côté d'une couche de substrat (couche A), la couche A contenant 70 % en masse ou plus d'un polyamide 6, et la couche B contenant un copolymère de polyamide 6, une proportion de 60 à 100 % en masse d'un composant de copolymérisation étant de 3 à 35 % en masse, et de 0 à 40 % en masse d'un polyamide 6.
(JA) 【課題】 耐水接着性(耐水ラミネート強度)、耐衝撃性、耐ピンホール性に優れた積層延伸ポリアミドフィルムを提供する。 【解決手段】 基材層(A層)の少なくとも一方の面に易接着層(B層)が積層された積層延伸ポリアミドフィルムであって、前記A層は70質量%以上のポリアミド6を含有し、前記B層は60~100質量%の共重合成分の比率が3~35質量%であるポリアミド6共重合体と0~40質量%のポリアミド6を含有する積層延伸ポリアミドフィルム。
