  • System and method for producing polymeric film
    Patent number: 6277314
    Abstract: Efficient, improved output systems and methods for producing polymeric film are described. Such systems include a feed assembly for positively and substantially constantly feeding polymeric raw material to a grooved feed extruder. The system also includes suitable apparatus for forming the molten polymer output from the extruder into film. The raw material may consist of 100% pelletized polymer, 100% polymer fluff, or any combination of the two. If necessary, a blending apparatus is included to blend the pellets and fluff prior to feeding the raw material to the extruder.
