PROBLEM TO BE SOLVED: To provide a polyolefin film preferable for packaging, a photoresist cover film for photosensitive plate making or the lime, which has excellent characteristics for recycling. SOLUTION: The polyolefin film is formed by laminating a polyolefin film (B layer) on at least one side of a biaxially oriented polyolefin film (A layer). The B layer has a ratio Rmax/Ra in a range of 5-15 where Rmax is a maximum surface roughness, Ra is a center line average surface roughness, and the number of ridges SPc per 0.1 mm2 on the surface is 10 or more. A sum of Young's moduli in a longer direction and a widthwise direction of the film is 1.5 GPa or less. |
