Abstract
A polyolefin film containing a polyolefin, wherein the polyolefin contains polyethylene, a melting point of the polyolefin film is 134° C. or higher and 140° C. or lower, a basis weight-equivalent puncture strength Sm of the polyolefin film is 70 gf/(g/m2) or more and 150 gf/(g/m2) or less, and a shutdown temperature Ts and the Sm of the polyolefin film satisfy the following relationship: Ts<0.13×Sm+130.
