Bandera Luigi Costruzioni Meccaniche and Processing Technologies LLC announced a strategic business alliance to supply dryerless sheet lines with the patented HVTSE technology to the North American market, for running PET and polylactic acid.

This process relies on Bandera’s patented High Vacuum Twin Screw Extruder (HVTSE) technology, which allows PET to be processed without the need for raw material drying and crystallizing. The HVTSE extruder de-volatilizes and de-moisturizes the material as part of the extrusion process.

The twin-screw extruder will be integrated with downstream systems furnished by PTi, a global supplier of single-screw sheet extrusion systems, as part of a turnkey package. PTi will also provide its Titan supervisory control system and UL approved electrical components for delivery throughout North America.

The companies will install a production-scale demonstration line at PTi headquarters later in 2010.

While widely accepted and implemented throughout Europe and other parts of the world with more than 80 Bandera HVTSE installations, this technology is fairly uncommon to the North American marketplace.

“PTi has been investigating options for ‘dryer-less’ technology in response to growing North American customer interest – said John Chalmers, PTi’s VP of Sales and Marketing -. All of our research pointed to Bandera’s HVTSE system as the most efficient, robust, industry proven solution. And since PTi does not manufacture twin screw extruders, we felt Bandera would be interested in selling the HVTSE system under license or a similar arrangement. Our concept was met with a welcome response since Bandera was also seeking a partner for development of the North American market for the HVTSE technology, so we were a perfect match-up.”
