Title
(EN) Laminated polypropylene film
(ZH) 层叠聚丙烯薄膜
Abstract
(EN)
Provided is a laminated polypropylene film that has a gas barrier performance comparable to polyvinylidene chloride-coated polypropylene films, and comprises: a film that uses a propylene polymer; anda thin-film layer having an inorganic compound as the main component thereof. The laminated polypropylene film comprises: a polypropylene film base that uses a polypropylene resin; and a thin-film layer having an inorganic compound as the main component thereof, and the laminated polypropylene film is characterized by having a longitudinal heat shrinkage ratio at 150 DEG C of not more than 7%, and having an oxygen permeability of not more than 150 mL/m2/day/MPa.

(ZH)
提供:具有与涂覆有聚偏二氯乙烯的聚丙烯系薄膜匹敌的阻气性的、具备使用丙烯系聚合物的薄膜和以无机化合物为主要成分的薄膜层的层叠聚丙烯薄膜。一种层叠聚丙烯薄膜,其特征在于,具备:使用聚丙烯系树脂的聚丙烯薄膜基材;和,以无机化合物为主要成分的薄膜层,层叠聚丙烯薄膜的150℃下的纵向的热收缩率为7%以下,透氧度为150mL/m2/day/MPa以下。
