Method and apparatus for uniformly stretching thermoplastic film and products produced thereby |
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. |
