Industrial triad to promote foamed PET bottles.

PET preform and bottle design specialist Plastic Technologies Inc. (PTI), Holland, Ohio, has enlisted two partners to help in commercializing its oPTI foam-overmolded lightweight PET bottles. German moldmaker Foboha GmbH (U.S. office in Beverly, Mass.; and machine builder Ferromatik Milacron, a German unit of Milacron LLC, Batavia, Ohio (, will collaborate with PTI to improve speed to market and commercial viability for overmolded oPTI bottles. Introduced at NPE 2009, these bottles consist of a pearlescent foamed PET inner layer and clear PET outer skin produced by overmolding a second layer onto the preform. They can provide unusual visual and tactile appeal while reducing colorant usage to a single layer. The dual-layer structure can be used to optimize barrier properties--for example, with an oxygen barrier in one layer and a CO2 barrier in the other. Foboha builds rotary cube-type stack molds for multi-material molding. The three companies jointly aim to improve cost-efficiency of the oPTI bottle process, which has been the main hurdle so far.
