PURPOSE:To obtain the title film having specific haze value in state where waterdrop or water membrane is attached to the inside of packaging film and having excellent fog resistance when an article having high water content is packaged and the packaging film is thermally shrunk and then packaged article is refrigerated and stored at ambient temperature by using a polyethylene to which a specific anti-fogging agent is added. CONSTITUTION:(A) One or more kind of polyethylene glycol fatty acid esters (having <=450 molecular weight of polyethylene glycol part) having 8-22C fatty acid group and (B) one or more kind of polyhydric alcohol fatty acid ester (preferably diglycerin stearate) of ester of polyhydric alcohol having >=4 OH and fatty acid used as anti-fogging agents are incorporated into a polyethylene polymer, preferably obtained by using a linear low density polyethylene and having 0.86-0.93g/cm<3> density at 25 deg.C and 0.2-2.0g/10min melt index to provide the aimed film having <=5% haze in a state where waterdrop, etc., is attached to the inside of a packaging film when an article having high water content is packaged and the packaging film is thermally shrunk in an amount of >=5% and then stored at 1-30 deg.C. |
