ABSTRACT:
A method for treating the surface of a polyolefin resin molded article is disclosed, comprising applying a running aqueous ozone solution in the form of a stream (or a waterfall) or spray onto the surface of a polyolefin resin molded article to oxidize the surface of the molded article for modifying the surface. Surface modification can be carried out on the same line in a series of processing, and extremely satisfactory results can be obtained by a short-time treatment with reduced energy. A coating layer formed on the modified surface exhibits high adhesion.
