PROBLEM TO BE SOLVED: To provide a polyethylene film excellent in self-adhesion inhibition and slipperiness by dry heat and wet heat history, free from the possibility of debris contamination to ingredients when constructing a container and the like, and excellent in film appearance.SOLUTION: The above problem is solved by a polyethylene film containing three kinds of high density polyethylenes having density of 950 kg/mrespectively, by mass ratios, a MFRcomponent of 60 to 70%, a MFRcomponent of 3 to 5% and a MFRcomponent of 25 to 37% and MFR ratios, MFR/MFRof 300 to 500 and MFR/MFRof 2 to 5, where MFR, MFR, MFRare melt flow rates of the three kinds of high density polyethylenes respectively. |
