Laminated sheet construction with thermal adhesive surface and method for making same

摘要

A laminated sheet construction for use in product packages has a substrate layer onto which there is laminated a transparent solid plastic film with an exposed surface having a transparent thermosetting adhesive coating. The surface beneath the coating may be printed with text and/or graphics which is visible through the film and adhesive. A container for a product may be directly affixed to the adhesive surface. Panels of the laminated substrate may be bonded together for increased strength or for capturing the flange of a container which can project through a window in one of the panels while displaying printing on the other panel through the window.

1. A method of making a laminated sheet construction comprising
coating a sheet of solid film material, which a barrier to oils, fragrances or scents, with a layer of a thermoplastic adhesive to form an adhesive side of said sheet of solid film material, an opposite side of said solid film material being a film side of said solid film material, coating said film side of said solid film material with a setting adhesive, placing said sheet of solid film material onto a substrate of sheet material with said film side of said solid film material facing a front surface of said substrate, and causing said setting adhesive to set for adhering said sheet of solid film material to said front surface of said substrate thereby forming a laminated substrate having a thermoplastic adhesive surface.
