Abstract
PURPOSE:To improve heat seal property, moisture barrier characteristics and gas barrier characteristics, by a method wherein the title material is provided with a light absorbing and light shielding film layer, containing carbon black and anti-oxidizing agent, and a light reflecting and light shielding film layer, containing fatty acid or fatty acid compound, white pigment and metallic powder. CONSTITUTION:A light absorbing and light shielding film layer contains ethylene copolymer resin for improving heat sealing property and carbon black of preferably at least 0.1g per 1m<2> of the film layer while 0.001-1.0 weight % of anti- oxidizing agent is added in the film layer. A light reflecting and light shielding film layer is preferable to be constituted of polyamide, polyester, polypropylene and various polyethylenes having the density of at least 0.93g/cm<2>. Fatty acid or fatty acid compound is contained to improve the dispersing property of metallic powder and it is preferable to contain white pigment of 0.1g or more per 1m<2> of the film layer and 0.1g or more of metallic powder. The packing material for photosensitive substance is constituted of a multi-layer co-extruded light shielding film having the light absorbing and light shielding film layer and the light reflective light shielding film layer.
