  • Publication number: 20080182046
    Abstract: A method of forming a multi-component molded article is described. The method includes first introducing a first plastic film and a second plastic film separately into a first cavity of an injection mold, the first and said second plastic films each being positioned within the first cavity so as to form a void there-between. Next, a first thermoplastic material is injected into the void, thereby forming a first molding. The first molding is then released from the mold, and the first molding and at least one second molding are together introduced into a second cavity of the mold. Finally, a second thermoplastic material is injected into the second cavity of the mold, thereby combining the first molding and second molding together thus forming a multi-component molded article.
