The disclosure describes a method of making a molded article having a film layer on its exterior surface that provides a surface finish to the article; the method consists in first placing a thermoplastic film in a two-partmold having a negative recessed border undercut in one of its part and in vacuum forming, under heat conditions, the film to make a preform having inward folded edge having a shape corresponding to that of the recessed border undercut. After removing the preform from the mold, part of the preform edge is trimmed to leave an inward peripheral edge along the preform which is then placed in a second mold wherein molten plastic is blown or injected; the plastic of the peripheral edge melts with the plastic to provide an intimate bonding at the peripheral edge of the article.
