PURPOSE: To film, obtained by incorporating a high-pressure polyethylene with a nonionic surfactant, and forming the film from the resultant composition, having improved self-tack properties, cutting property, heat resistance and transparency, usable for cooking in an electronic oven, and nontoxic and safe in incinerating and discarding.
CONSTITUTION: A packaging film obtained by forming the film from a composition prepared by incorporating high-pressure polyethylene having 0.928W0.940g/ cm3 with a nonionic surfactant, preferably polyoxyethylene alkyl phenyl ether. The above-mentioned polyethylene to be used has 1W10, preferably 2W8 melt index, and the amount of the nonionic surfactant to be used is 0.5W5pts.wt. based on 100pts.wt. polyethylene. The thickness of the film is 6W50μ, preferably 8W20μ.
