DUSSELDORF, GERMANY — Bruckner Maschinenbau GmbH is finding new customers for an innovative film technology that it licensed in 1993 from DuPont.
Bruckner, based in Siegsdorf, Germany, completed a pilot line in July for the technology, which the company dubbed LISIM. The equipment uses sophisticated, linear motors to stretch film in a controlled, continuous process in two directions simultaneously — pulling it away from the extruder and pulling it to make it wider. The process can be used to make thin, strong biaxially oriented films using polypropylene, PET, nylon or polystyrene.
DuPont developed the technology, initially for PET, but Bruckner acquired rights to the process and developed an industrial system for high-capacity production lines.
Several weeks ago, DuPont installed a PET film line using the technology at its plant in Luxembourg. In addition, Bruckner has installed a pilot line for Minneapolis-based 3M Co., said Jurgen Breil, Bruckner's head of research and development.
Within the next six months, two high-capacity lines will go into production: one for 3M and a second for Bimo Italia SpA of Milan, an Italian BOPP film manufacturer. Both of those lines will have capacity to extrude 57.3 million pounds annually, Breil said.
Bimo already has ordered a second, similiarly sized machine, Breil told attendees at the Specialty Plastic Films '98 conference, held Oct. 19-21 in Dusseldorf.
