<p>A self-adhesive protection film is provided to be easily unwound after delayed storage in a roll form, and to ensure sufficiently high initial stickiness that does not cause detachment on bonding under stress during coating. A self-adhesive protection film has a back side of which one side is coated with an adhesive. The back side includes at least two layers, wherein the first layer comes into contact with the adhesive and comprises a non-oriented film containing at least one propylene block copolymer in an amount of 10-95%(w/w), and the second layer touches away from the adhesive and comprises film containing at least 75 %(w/w), preferably at least 80 %(w/w) of low density polyethylene.</p> |
