BIAXIALLY-STRETCHED LAMINATED POLYPROPYLENE FILM

摘要

PROBLEM TO BE SOLVED: To provide a laminated film free from surface roughening despite inclusion of a polymeric antistatic agent, excellent in transparency, slip characteristics and antistatic performance.

SOLUTION: The biaxially-stretched laminated polypropylene film comprises an antistatic resin composition including: 5-10 mass% of a block polymer (A) having a structure such that the blocks of polyolefin (a) and hydrophilic polymer (b) bond alternately and repeatedly and having a surface resistivity of 1×105-1×1011Ω-cm; 5-50 mass% of a propylene-based polymer (B); and 40-90 mass% of a propylene/α-olefin random copolymer (C). The biaxially-stretched laminated polypropylene film has the surface layer of the polypropylene film having a mass ratio of the propylene-based polymer (B) to the random copolymer (C) of 1:1 to 1:9.
