Patent ID: 7897087

Claim:
A method of manufacturing a high surface energy molded article with an injection mold having an inner surface, the method comprising: applying a chlorinated polyolefin to a low adhesive sheet to form a chlorinated polyolefin film; removing the chlorinated polyolefin film from the low adhesive sheet; applying the chlorinated polyolefin film to the inner surface of the injection mold; introducing a thermoplastic resin having a temperature of at least 190 degrees Celsius on the chlorinated polyolefin film in the injection mold, the thermoplastic resin having a predetermined heat energy, to transfer at least a portion of the heat energy of the thermoplastic resin to the chlorinated polyolefin film; defining a molded article having a surface; maintaining contact of the thermoplastic resin and the chlorinated polyolefin film for a predetermined time period to diffuse the chlorinated polyolefin film through at least a portion of the surface of the molded article; and increasing the surface energy of the portion of the molded article for enhanced adhesion.
