Abstract: A method for forming a multilayer elastomeric laminate comprises laminating an elastomeric film onto a first substrate to form a laminate web having an elastomeric film surface, and slitting the laminate web to form laminate strips. At least one strip is then bonded on its elastomeric film surface to a second substrate having a width greater than the width of the laminate strip to form a multilayer elastomeric laminate. The multilayer elastomeric laminate may then be subjected to additional processing, including but not limited to activation, aperturing, and/or lamination to other materials.

Abstract: 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.
