Materials are then all pressed together in a pressure nip.
On the left side of Figure 5, an adhesive is applied to the substrate. After the materials are combined, they are cast on a chill roll to quench the molten resin. They are then wound up on the bottom right as a product roll. This method allows the converter to use two substrate materials. For example, the converter could combine an oriented nylon substrate with a paper or a foil, and extrude polyethylene between them.
