Abstract

PURPOSE: To provide the title packaging material having excellent transparency, gloss, low-temperature heat-sealability, and slippery, composed of a substrate layer comprising a propylene polymer and a surface layer containing an ethylene-propylene copolymer and a low molecular thermoplastic resin.
CONSTITUTION: The title packaging material is prepared by covering one side or both sides of a substrate layer composed of a propylene polymer with a polymer mixture composed of (A) 75W97 wt% of a resin mixture containing 5W85 wt% of an ethylene-propylene copolymer and 95W15 wt% of a copolymer derived from butene and an ethylenically unsaturated monomer (except butene) and (B) 3W25 wt% of a low-molecular thermoplastic resin, e.g. natural or synthetic wax, hydrocarbon resin, etc. Pref. 0.01W0.15 parts by weight of a silicone oil is added to 100 parts of the polymer mixture.
