POLYPROPYLENE RESIN COMPOSITION FOR HEAT SEAL

摘要

PURPOSE: A polypropylene resin composition is provided to secure the low temperature adhesive property of the composition, and to improve the printability and the transparency of a film applied with the composition. CONSTITUTION: A polypropylene resin composition contains the following: 81~99 parts of propylene-ethylene random copolymer by weight including 1~20mol% of ethylene; 0.5~8 parts of polyethylene by weight polymerized by using a metallocene catalyst; 0.5~10 parts of polybutene by weight; and 0.01~1 parts of anti-blocking agent by weight. The propylene-ethylene random copolymer includes more than two kinds of propylene-ethylene random copolymer units with different contents of the ethylene.
