Abstract

PURPOSE: To prepare a polyprophlene composite film having excellent low temperature heat sealability and improved sealing strength, and free from tackiness and blocking, by laminating specific propylene-1-butene random copolymer film onto a polypropylene film.
CONSTITUTION: An isotactic polypropylene film having a thickness preferably of 10W60μ is laminated with a film of a propylene-1-butene random copolymer having a thickness of pref. 3W30μ, a melt index of 0.1W100, a propylene content of 50W87 mole %, a heat of crystal fusion of 10W80 joule/g, ≤ 2 wt.% of the soluble part in boiling methyl acetate and ≤ 5 wt.% of the insoluble part in boiling n-heptane.
EFFECT: The composite film has excellent transparency and scratch resistance, and heat sealability at a wide temperature range.
