Abstract
A polypropylene resin composition is provided by incorporating a metal salt of a fatty acid and the oxide or hydroxide of an alkaline earth metal, each, in an amount of 0.05-1 part by weight based on 100 parts by weight of polypropylene. The polypropylene resin composition shows excellent thermal processing stability even when subjected to remelting and extrusion molding after mixing of a scrap recycled from the production of multi-layered containers or sheets each of which is formed of a gas barrier layer made of nylon or an ethylene-vinyl alcohol copolymer and another layer made of a polypropylene resin composition.
