RANDOM POLYPROPYLENE RESIN COMPOSITION FOR EXTRUSION COATING

摘要

PURPOSE: A random polypropylene resin composition for extrusion coating is provided which keeps a good heat adhesive property and has an excellent strength, a transparent property and a neck-in property. CONSTITUTION: The random polypropylene resin composition for extrusion coating comprises: (i) 70-90 wt.% of propylene-ethylene random copolymer resin having an ethylene content of 3-7 mol% and a melt index of 20-30 gram/minutes; and (ii) 10-30 wt.% of low density polyethylene resin. Where the low density polyethylene resin has a melt index of 5-10 gram/minutes.
