Leistritz soon adding even larger twin-screw unit

Away from the compounding extruder field with which it is normally associated, Leistritz has found a new market for its equipment in the production of bioriented polypropylene (BOPP) film. It recently delivered a ZSE135 MAXX extruder to Austrian/French tenter frame producer DMT (Salzburg, Austria) to melt and extrude PP for biaxially stretched films targeting the food packaging sector. “The ZSE135 MAXX has a screw diameter of 140mm and facilitates high torque with at the same time large free volume in the screw,” says Peter Zubak, regional sales manager at this extruder manufacturer. DMT has integrated 16 such extruders from 75-140mm in screw diameter into their lines.
