More details on a new family of barrier and oxygen-scavenger resins from The Valspar Corp., Minneapolis, will be revealed in February at Nova-Pack America 2006, The 20th International Conference on PET Containers for Food & Beverages, in Amelia Island, Fla. The conference is sponsored by Schotland Business Research Inc., Pitman, N.J. ValOR resins, which were mentioned in our August cover story on barrier PET bottles, can be used as a passive barrier and oxygen scavenger layer in a multilayer container or can be blended with PET to produce relatively clear monolayer containers.
ValOR is a family of proprietary thermoplastic polyesters that are claimed to be less prone to delamination than other barrier resins used in multilayer PET bottles. Also, the new resins are inherently clear. Some grades are moisture activated while others are not.
Target applications include beer and single-serve carbonated soft drinks. The materials are commercial in Europe and undergoing trials in the U.S. Valspar: (612) 332-7371/PTDirect: 665SX • Schotland: (609) 466-9191/www.schotland.com
