To obtain the subject composition capable of forming a film having a low coefficient of dynamic friction, excellent slipperiness and high transparency, by compounding a polyolefin-based resin with specific spherical resin fine particles and a higher fatty acid amide.

This composition is obtained by compounding (A) 100 pts.wt. of a polyolefin-based resin with (B) 0.01-0.3 pts.wt. of spherical resin fine particles obtained by copolymerizing an organosiloxane of formula I (R is a 1-12C monofunctional hydrocarbon and ≥50 mol.% in the whole R is methyl; X is a radically polymerizable functional group-containing organic group; (n) is an integer of 5-200) with a non-crosslinkable radically polymerizable monomer and a crosslinkable radically polymerizable monomer, having 1.45-1.52 refractive index, 0.5-8 μm average particle diameter and ≥0.8 sphericity (f) and (C) 0.01-0.3 pts.wt. of a higher fatty acid amide. The sphericity (f) is a value obtained by formula II (M is an arbitrary cross section (mm2) of fine particles; Nmax is the maximum diameter of the cross section (mm)).
