摘要
An easy and clean surface reforming method for a plastic molded product is disclosed.;A surface reforming method for a plastic molded product of this invention is characterized by comprising a step (a) for immersing a plastic molded product into supercritical carbon dioxide or subcritical carbon dioxide under a temperature lower than the glass transition temperature of said plastic, and a step (b) for vaporizing carbon dioxide adhered to the surface of the plastic molded product under a temperature lower than the glass transition temperature of said plastic. A plastic molded product may be composed of a polymer having a polar group. Examples of such a plastic molded product are a biaxially oriented polyester film, an unoriented polystyrene film, and a biaxially oriented polystyrene film.
