HEAT-SHRINKABLE POLYESTER FILM

摘要

PURPOSE:To provide a heat-shrinkable film having excellent properties such as heat-shrinkability on a par with a polyvinyl chloride film and very little formation of shrinked spots and pockmarked wrinkles when shrunk with heat by using a polyester film excellent in transparency, heat resistance, mechanical strength and chemical resistance, without problems such as the generation of a toxic gas and damage, to a firing furnace during firing thereof in a waste treatment. CONSTITUTION:The objective heat-shrinkable polyester film made from a polyethylene terephthalate polymer having a glass transition temp. (Tg) of 40 to 80 deg.C blended with 5-10wt.% arom. polycarbonate.
