Abstract
A process for the manufacture of a composite laminate which includes a thermoplastic film laminated to a substrate. The front surface of the film has a regular embossed pattern of protrusions which have a height in the range of 0.5 to 10 microns and a separation in the range 20 to 400 microns. The rear surface of the film confronts and is bonded to the substrate. The manufacturing process of the composite includes the steps of applying a layer of a melt adhesive between the rear surface of the film having a regular embossed pattern on its front surface and the substrate to form a composite, and running the composite of the film, the layer and the substrate between nip rollers to apply pressure to the composite whilst the adhesive is in a heated condition, so as to effect thermal lamination of the film to the substrate.
