Statistisches Copolymer auf Propylen-Basis und Harzzusammensetzungen auf Propylen-Basis, Folien daraus und Harzlaminate auf Propylen-Basis

摘要

The invention provides (1) a propylene-ethylene-1-butene random copolymer having specific properties, (2) a resin composition comprising a propylene-ethylene-1-butene random copolymer with specific properties, and a nucleating agent, (3) a resin composition comprising a propylene-ethylene-1-butene random copolymer with specific properties, and a propylene-based polymer; and their films, and multi-layered, propylene-based laminates of which the outermost layer is made of a specific propylene-based polymer. The films and the laminates exhibit excellent heat-sealability, and have good slip characteristics and good anti-blocking characteristics.
