  • Apparatus and method for reducing die accumulation
    Patent number: 6358449
    Abstract: A polymeric film extrusion die having a die body with a molten polymer inlet, a molten polymer exit, and forming a molten polymer conduit providing a fluid communication between the molten polymer inlet and the molten polymer exit. The die body includes a peripheral edge at a periphery of the molten polymer exit, which peripheral edge has a thickness less than or equal to about 0.005 inches. The apparatus further includes a molten polymer exit heated gaseous fluid supply adapted to provide heated gaseous fluid proximate the molten polymer exit so as to maintain the die temperature at the molten polymer exit as low as possible without affecting the processability/integrity of the product film.
