CRYSTALLINE RESIN COMPOSITION AND CRYSTALLINE RESIN FILM

摘要

A crystalline resin composition and a crystalline resin film having excellent gas barrier properties, transparency and slip characteristics are provided. The crystalline resin composition comprises 100 parts by weight of a crystalline resin (A) and 0.01 to 0.5 parts by weight of a porous filler (B), said porous filler (B) comprising a spherical porous filler (B-1) having an average particle size of 1.5 to 6 µm and a polyhedral porous filler (B-2) having an average particle size of 0.4 to 1.5 µm, with their weight ratio falling in the range of 1/90‰ (B-1)/(B-2)‰ 1/1, and the crystalline resin film having such properties that its oxygen permeability at 23°C and 65% RH is not more than 50 ml/[m 2 ·day·atm] when the film thickness is 15 µm, its haze is not more than 2.5%, and the coefficient of static friction between the films is not more than 0.5 at 23°C and 65% RH and not more than 0.6 at 23°C and 90% RH.
