OLEFINIC RESIN COMPOSITION FOR FATTY FOOD PACKAGING

PROBLEM TO BE SOLVED: To obtain an olefinic resin composition for packaging fatty foods such as butter or the like, having a high water resistance enough to permit sterilization treatment and good folding line-forming properties by formulating a prescribed amount of a mica powder coated with silica on its surface to a polyolefin resin. SOLUTION: This resin composition is prepared by formulating (B) 1-50 pts.wt. of a mica powder of which surface is coated with silica, preferably, in addition, (C) 0.01-5 pts.wt. of a fluorine resin to (A) 100 pts.wt. of a polyolefin resin. The component (B) is, for example, a scaly mica powder with a high aspect ratio, for example, platelet shape with an average longer axis of 20-40μm, while the component (C) is tetrafluoroethylene and the objective resin composition is prepared by mixing these components with, for example, a Henschel mixer and granulating by means of an extruder.
