Abstract

PURPOSE: Title film or sheet that contains an platy inorganic filler and a titanium oxide powder, thus being used for steriled packaging of food because of preventing the oxidative deterioration of food even in the presence of oxygen and having white appearance.
CONSTITUTION: (A) A resin prepared by adding 1 W 10 wt% of vinyl aromatic copolymer elastomer to a styrene resin, preferably high-impact styrene resin, is kneaded with (B) 1 W 20, preferably 3 W 20% of a platy inorganic filler with average particle size of no less than 1 micron (more than 50% particle size distribution) as clay, (C) 1 W 15, preferably 3 W 15 wt% of a titanium oxide powder, resulting in less than 35 wt% in total, and they are laminated with polyethylene or others to produce said light-screening material having oil resistance and gas barrier properties.
