POLYPROPYLENE RESIN COMPOSITION, FILM OR SHEET, STRETCHED FILM OBTAINED FROM SUCH FILM OR SHEET, MULTILAYER BODY, AND STRETCHED FILM OBTAINED FROM SUCH MULTILAYER BODY

摘要

The present invention provides a polypropylene resin composition having good moldability and giving a film or a sheet that is excellent in transparency and heat-sealing properties.;A polypropylene resin composition of the present invention comprises 1 to 50 wt% of a propylene polymer (A) whose melting point Tm as measured with a differential scanning calorimeter (DSC) is 150°C or higher, 10 to 90 wt% of a propylene copolymer (B) whose melting point Tm is 100°C or higher and below 150°C, and 1 to 80 wt% of an olefin copolymer (C) whose melting point is 40°C or higher and below 100°C, comprising 50 mol% or more of a constitutional unit derived from either one of propylene or 1-butene (a) and 50 mol% or less of a constitutional unit derived from an α-olefin having 2 to 20 carbon atoms (b) other than the constitutional unit (a) (here, the sum of (a) and (b) is 100 mol%).;A film obtained from this resin composition is suitable as a packaging film for food and the like.
