Abstract
A polyolefin resin composition for a film which consists essentially of a mixture of 100 parts by weight of a polyolefin resin with (a) 0.01-3.0 parts by weight of an antiblocking agent, the surface OH group content of which is 200 .mu.mol/g or less. The resin composition may further contain (b) 0.05-2.0 parts by weight of an antistatic agent consisting of (A) a glycerine fatty acid ester and (B) an alkyldiethanolamide in a weight ratio of A/B of 50/50-95/5 for antistatic film or (c) 0.05-3.0 parts by weight of at least one member selected from the group consisting of polyhydric alcohol fatty acid esters, alkylene oxide adducts of polyhydric alcohol fatty acid esters and higher alcohol-alkylene oxide adducts as an antifogging agent, or (d) 0.01-3.0 parts by weight of a phenol type antioxidant and (e) 0.01-0.2 part by weight of a phosphorous type antioxidant for forming a stabilized film.
