POLYPROPYLENE RESIN COMPOSITION FOR EXTRUSION COATING

摘要

PURPOSE: To obtain a polypropylene resin composition which shows high-speed moldability in extrusion-coating a base material and can give a coated molding excellent in transparency and low-temperature heat-sealability. CONSTITUTION: The polypropylene resin composition for extrusion coating comprises 70-90wt.% polypropylene resin having a melt flow rate(MFR) of 7-15g/10min and prepared by degrading, in the presence of an organic peroxide, a crystalline polypropylene resin having an MFR of 0.1-3.0g/10min and 30-10wt.% low-density polyethylene and/or amorphous or lowly crystalline ethylene/α-olefin copolymer.
