Plaskolite has purchased the North American Vivak polyester sheet business from Bayer MaterialScience. Terms of the deal were not disclosed, except that all Bayer employees involved in the business will remain with Bayer. Vivak is a glycol-modified copolymer PET sheet used in point-of-sale displays, vending machines, promotional signage, and food packaging. Dennis Duff, managing director of Bayer’s sheet business in the NAFTA region, said in a news release that the deal will allow his company to focus on its Makrolon polycarbonate sheet business, “and this sale will free up additional capacity for strengthening this focus further.” BMS has a sheet production plant in Sheffield, Mass. The company expanded its PC sheet business earlier this year when it acquired the Tuffak name and PC sheet production assets in the US from Arkema.
