POLYPROPYLENE-BASED RESIN SHEET FOR PRESS-THROUGH PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene-based resin sheet for press-through package(PTP) having a wide moldable temperature range and suppressed in generating curls during heat molding the resin sheet. SOLUTION: This polypropylene-based resin sheet for PTP comprises at least one species of polymers selected from a propylene homopolymer and an ethylene/propylene copolymer having <1 wt.% content of ethylene repeating units, a propylene/butene-1 random copolymer containing 10-30 wt.% of butene-1 repeating units and a filler. When the sum total of the aforesaid polymer and the propylene/butene-1 random copolymer is brought to be 100 pts.wt., the content of the polymer is 80-95 pts.wt.
