In the production of polyethylene film on a blown film extruder, the issue of recycling the cut edge of the edge always arises.
For these purposes, a cut edge utilizer is used. It consists of a shredder, a cyclone and a screw conveyor system for automatic feeding the shredded edge back into the extruder barrel. The cut edge utilizer is used in conjunction with extruders with a screw diameter of 55 mm or more and allows efficient disposal of production waste.
