Abstract
A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.
Claims15
A method of making a composite sheet material, comprising:
- providing a cover sheet having a cover sheet material, the cover sheet material including polyethylene terephthalate;
- providing a substrate having a substrate material, the substrate material including polypropylene;
- providing an adhesion promoting layer disposed between the cover sheet and the substrate;
- performing a first formation process to combine the cover sheet, the substrate and the adhesion promoting layer, the first formation process including drawing polypropylene from the substrate and into the adhesion promoting layer.
