PET blow molding equipment supplier SIG Corpoplast GmbH said it has orders for its Plasmax barrier coating process, which last year won approval from the Food and Drug Administration.
SIG of Hamburg, Germany, jointly developed Plasmax with Schott HiCotec of Mainz, Germany.
Plasmax uses plasma impulse chemical vapor deposition to coat PET bottles, significantly reducing the penetration of oxygen or the loss of carbon dioxide and boosting the shelf life of the contents.
A Swiss juice bottler, Bischofszell Food Ltd., is using an industrial-scale prototype of Plasmax. The company can run 10,000 PET bottles per hour through the coating machine. In Japan, Hokkai Can Ltd. of Tokyo has installed a Plasmax line. SIG said Hokkai is the largest global producer of plasma-coated PET containers.
SIG was scheduled to deliver the line to Hokkai early this year. Hokkai is interested in using Plasmax for hot-fill bottles, food, beer and other applications.
SIG's U.S. headquarters, SIG Plastics Technologies (USA) Inc., is in North Branch, N.J.
