Abstract
A polyolefin resin composition obtained by mixing a polyolefin resin with minor proportion of a polybutene of low molecular weight, a mixed glyceride containing a lower acyl group and a higher acyl group, and preferably a surface wetting agent, is used to form a polyolefin film, which is thereafter aged. The thus formed film exhibits very excellent adhesion strength as well as very good transparency and physical strength, and is therefore suitable for use as a food packaging film.
