Packing materials for molten contents

Abstract

A packing material for molten contents is composed of a base film coated with a resin (C) containing an ethylenevinyl acetate copolymer (A) having a vinyl acetate content of approximately 5 to 40 percent by weight and a copolymer (B) of either ethylene or an alpha-olefin with an unsaturated carboxylic acid or its anhydride, having a molecular weight of approximately 2,000 to 20,000, and having the following formula: ##STR1## (wherein R stands for a hydrogen atom or an alkyl group having between 1 and 98, carbon atoms, inclusive, and X stands for a residue of an unsaturated carboxylic acid or its anhydride), in an (A) to (B) ratio between approximately 99:1 and 60:40 by weight or coated with the resin (C) to which a tackifying agent (D) is added in an amount between approximately 3 and 30 percent by weight.
