PURPOSE:To produce a polyolefin-based matte film which has a high-quality appearance, is excellent in matte effect, tensile modulus, flexibility, etc., and is useful as a film for a self-adhesive tape substrate, a building interior, an automobile trim, etc. CONSTITUTION:The objective matte film comprises a compsn. consisting of 10-90wt.% propylene (co)polymer with an MFR of 1-20g/10min and 90-10wt.% ethylene/3-12C alpha-olefin copolymer with specified properties and has a ratio of the MFR of the former polymer to that of the latter of 5-20 and/or a difference in crystallization temp. between the two polymers of at least 5 deg.C. |
