Abstract

PURPOSE:To obtain the title film which can prolong the period during which the quality or freshness of food can be kept in a wide temperature range by mixing porous particles having an ethylene gas absorptivity with specified ceramic particles and an antibacterial or bacteriostatic substance. CONSTITUTION:0.5-10wt.% additive comprising 20-80wt.% porous particles (e.g., active carbon) having a particle diameter <=30mum and an ethylene absorptivity, 1-50wt.% ceramic particles having a high infrared radiating effect (e.g., SiC) and 0.1-5wt.% substance having an antibacterial or bacteriostatic effect (e.g., thiobenzothiazole) is added to a film base, and the mixture is formed into a film.
