PURPOSE:A crosslinked film excellent in adhesion to flat bases, prepared by irradiating a polyolefin film containing a specified organosilane compound with an ionizing radiation. CONSTITUTION:0.05-10wt% organosilane compound of the formula: YSi(OR)3 [wherein Y is a (polar functional group-substituted) alkyl, vinyl, cycloalkyl, or aryl group, and R is a (substituted) alkyl or aryl group], e.g., gamma-aminopropyltrimethoxysilane is added to a polyolefin (e.g., polyethylene or ethylene/vinyl acetate copolymer), and the resulting composition is melt-extruded through a T die or the like. The obtained film (thickness of about 10-300mu) is irradiated with an ionizing radiation (e.g., electron beams) at a dose of about 1-50Mrad to effect its crosslinking. |
