A multinational company in North America will launch the first commercial application of a new barrier technology to coat preforms used in PET bottles by the second quarter of next year, said one of its developers. He would not name the customer.
The water-based process coats preforms used in injection stretch blow molding using a specially developed barrier resin, said Robert Lee, principal of Advanced Plastics Technologies Ltd. of Bowdon. The company developed the technology with subsidiary Plastics Fabrication Technologies LLC of Long Beach, Calif.
The process is less expensive and the finished bottles more transparent than those made with traditional plasma coating, Lee said. The coating is applied at the end of the injection molding cycle.
The company hopes to license the technology for use in plastic beer and wine bottles, a growing market especially in Asia, Lee said. The first commercial application of the technology is with a nonalcoholic product, he added.
Husky Injection Molding Systems Ltd. of Bolton, Ontario, is providing specialty coating machinery that can be used in-line with a standard preform machine on the project, said Husky spokesman Tony Maraschiello. The speed of the modular coating machine can be matched to that of the preform injection press, he said.
