摘要： Thermoplastic films and laminates are made by extrusion and stretching using differential speed rollers employing a short stretching gap of no more than one inch immediately after the extruded film product is formed. The method and apparatus control the thickness of the stretched film and impart desirable mechanical properties thereto such as film products with a high modulus for handling and suitable tensile for softness.

摘要： A product, apparatus and process for lamination of a sheet of polymer film onto a sheet of light weight web material. An incoming sheet of material is slit into narrow webs, which may be folded by a folding guide, and separated by use of turning bars and guides. The narrow webs then enter an embossing or laminating station. The lamination process joins the two sheets which are of different widths to allow the process to produce stock for different final products. The laminate of folded webs and polymer may be slit and/or unfolded prior to being stored on a take-up reel.
