MULTILAYER FILM AND METHOD FOR PRODUCING SAME

MULTILAYER FILM AND METHOD FOR PRODUCING SAME

A laminated film having a resin layer laminated on at least one surface of a base film. The laminated film is characterized by: the base film being a semi-aromatic polyamide film that has been at least uniaxially stretched; the resin layer containing fine particles; the thermal shrinkage factor in t...

Zusammenfassung:A laminated film having a resin layer laminated on at least one surface of a base film. The laminated film is characterized by: the base film being a semi-aromatic polyamide film that has been at least uniaxially stretched; the resin layer containing fine particles; the thermal shrinkage factor in the longitudinal direction SMD and the thermal shrinkage factor in the width direction STD of the film measured under conditions of 250°C × 5 min each being -1.0 to 1.5%; the tensile elongations at break in the longitudinal direction and in the width direction each being 70% or more; and the haze being 3% or less.
