Propylene type resin composition, film made thereof, and laminated resin film

摘要

A propylene type resin composition comprising from 95.0 to 99.999 parts by weight of component (A) which is a propylene/a-olefin random copolymer polymerized by a metallocene catalyst, and from 0.001 to 5.0 parts by weight of component (C) which is a polyethylene wax, wherein components (A) and (C) satisfy the following conditions: Component (A): Propylene/alpha-olefin random copolymer 1) Melt index at 230° C.: 2 to 30 g/10 min 2) Main melting peak temperature (Tm) obtained by DSC: 110 to 145° C. Component (C): Polyethylene wax 1) Density: 0.94 to 0.98 g/cm3 2) Melt viscosity at 140° C.: At least 10 cps.
