PROBLEM TO BE SOLVED: To provide a polyolefin film having excellent transparency and sufficient blocking prevention performance by compounding odd-shaped resin particles having a specified shape. SOLUTION: The polyolefin film contains odd-shaped resin particles. Each of the resin particles is formed by two curved surfaces or by one curved surface and one plain surface, the curved surface being a convex surface. There is a border line between the two surfaces. In the side elevation in which the border line is in the transverse direction, a specific relational expression is satisfied by the maximum particle size D in the transverse direction and the maximum height d in the longitudinal direction.
