PET sheet extrusion line, no drying, on display this month and next

Processors interested in extruding and processing PET sheet without the expense and trouble of pre-drying their material, take note. We reported last year on the 10-yr sales agreement between Aurora, IL-based Processing Technologies International LLC (PTi) and Luigi Bandera Meccaniche S.p.A. (Bandera; Milan, Italy) in which Bandera will supply its twin-screw HVTSE extrusion systems to PTi for the North American market. These extrusion lines make use of Bandera's patented High Vacuum Twin Screw Extruder (HVTSE) technology, which allows polyethylene terephthalate (PET) to be processed without drying and crystallizing, and polylactic acid (PLA) without drying. The HVTSE extruder de-volatilizes and de-moisturizes the material during extrusion.
