The present invention aims to provide a film excellent in transparency, ease of slippage, and heat resistance, and the gist of the present invention is a polyolefin film obtained by measuring the film by DSC and obtaining crystals by an extrapolation method. The temperature Tc 0 was 110° C. or higher, the in-plane retardation of the film was 400 nm or lower, and the kinetic friction coefficient μd after heating at 130° C. for 10 minutes was 0.7 or lower. |
