Two new oxygen scavengers for food and beverage applications were unveiled at the Nova-Pack conference on PET food and beverage containers.
Valspar Corp. of Wheeling, Ill., launched its Activ300 fast-acting scavenger, building on its ValOR product line, introduced in 2006.
Scott Stamback, business director of packaging and emerging markets, said Activ300 ensures virtually no oxygen transmission for three to six months. The new scavenger is polyester-based, so it won't affect PET bottles' clarity, he said.
``We are in the middle of evaluating the recyclability. We had to bring in an outside contractor,'' Stamback said at Nova-Pack. The primary application for Activ300 will be juice bottles, ``which was a hole in our product line,'' he said.
Also at Nova-Pack, Wichita, Kan.-based Invista released details about its new oxygen scavenger, aimed primarily at beer and wine markets.
The polyester-based scavenger can extend product shelf life up to nine months, said Frank Embs, the firm's global commercialization manager.
Embs said the new scavenger complements Invista's PolyShield barrier resins in oxygen-sensitive packaging applications.
Currently awaiting U.S. and European regulatory approval, Invista expects to begin marketing the new scavenger commercially in 2009, he said.
