<p>The present invention provides an adhesive film and method for sealing openings in a rigid thermoplastic substrate such as a vehicle instrument panel retainer. The adhesive film includes an adhesive layer, which is adherable to the thermoplastic substrate, and a thermoformable base layer. In a preferred embodiment, the adhesive film is heat sealed around the openings of the substrate by a vacuum thermoforming process to prevent polymer foam from leaking through the openings during manufacture of the instrument panel.</p> |
