APPARATUS AND METHOD FOR MANUFACTURING BLOWN PLASTIC FILM FROM SCRAP PLASTIC

摘要

Apparatus and method for producing blown plastic film from scrap plastic (PS) including a grinder or shedder (12) which receives the crap plastic (PS) and feeds it to a crammer feeder (14) to increase the density of the scrap plastic (PS). The crammer feeder (14) is connected to a vented extruder (16) which melts the scrap plastic and passes through a filter or screen (18). The screen (18) is connected to a melt pump (20) that is connected to a mixer (22) that is in turn connected to a blown film die (24) which extrudes the plastic film (PF).
