Aqueous barrier coating offers cost benefits.A new barrier coating for PET preforms is claimed to cost less than competitive barrier solutions for carbonated soft-drink (CSD CSD Commission on Sustainable Development CSD Serbian Dinar (ISO currency code) CSD Christopher Street Day CSD Circuit Switched Data (Sprint) CSD Computer Science Department CSD Community School District ) and beer bottles. Advanced Plastics Technologies Ltd. (APT), Isle of Man Noun 1. Isle of Man - one of the British Isles in the Irish Sea Man British Isles - Great Britain and Ireland and adjacent islands in the north Atlantic , U.K., uses a proprietary water-based flow-coating process to apply a special thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. barrier resin. APT director Robert Lee says the new barrier process is expected to cost less than $10/1000 bottles. The first licensee, which Lee declined to disclose, is expected to manufacture CSD and juice bottles by the middle of this year. The preform pre·form tr.v. pre·formed, pre·form·ing, pre·forms 1.

The preforms are rotated while passing through a "waterfall" of coating solution. After the coating is cured, the preforms can be stretch-blow molded on standard equipment. The coating system reportedly keeps pace with large preform molding operations, turning out 30,000 coated preforms/hr. Under license from APT, Husky Injection Molding Systems, Bolton, Ont., has built several barrier-coating machines. These can be stand-alone units or purchased in combination with an injection press. An unnamed chemical company is supplying the new barrier material. Husky: (905) 951-5000 * PTDirect: 946LF |
