ABSTRACT:
An automotive trim strip laminate formed of a strip of polyester material bearing a layer of metallic material covered by a thin polyvinyl chloride layer bonded to a supporting substrate of a flexible plasticized polyvinyl chloride material is made so that the laminate can be thermally bonded to a support material along a curved path without any irregularity, which is recognized as caused by compression wrinkling from thermal stress along radially inner regions of the curved path. This is prevented by selecting the polyester strip and the thin polyvinyl chloride layer with physical characteristics and dimensions to provide the metallized polyester strip with sufficient dimensional stability relative to the polyvinyl chloride substrate to prevent any such compression wrinkling, and one preferred way is to make the thin polyvinyl chloride layer substantially unplasticized and formed of a smooth, medium impact material.
