An object of the present invention is to obtain a heat-resistant film that is excellent in processability during film production and that is less deformed and fused when subjected to high-pressure steam sterilization at 120 ° C. or higher and excellent in transparency. A polyethylene resin that satisfies the following requirements (A) to (D) is molded. (A) The density is 890 kg / m 3 or more and 980 kg / m 3 or less, (B) the number of long chain branches having 6 or more carbon atoms is 0.01 or more and 3 or less per 1,000 carbon atoms, (C) Both formula (1) and formula (2) are satisfied, MS 190 > 22 × MFR −0.88 (1) MS 160 > 110−110 × log (MFR) (2) (D) Ascending by differential scanning calorimeter There is one endothermic curve peak obtained in temperature measurement [Selection figure] None |
