New high-performance oxygen scavengers from Invista, Wichita, Kan., and Valspar Corp., Minneapolis, are said to significantly increase the oxygen barrier of PET containers. The new technologies will be presented at this month’s Nova-Pack 2008 conference in Orlando, Fla., sponsored by Schotland Business Research Inc., Skillman, N.J. Invista’s scavenger reportedly can extend the shelf life of oxygen-sensitive foods up to nine months. The polyester-based scavenger complements Invista’s PolyShield barrier resins for PET packaging of juices and wine. The scavenger is said to have excellent clarity and is expected to be compatible with PET recycling streams. Valspar has extended its ValOr product line with a new polyester-based scavenger that provides virtually zero oxygen transmission for up to six months. This performance is achieved at additive levels only about 20% as high as for previous oxygen scavengers. It also has better clarity and recyclability than competitive products, Valspar claims.
