Abstract
The zipper includes flanges which include an oxygen scavenging polymer. The oxygen scavenging polymer can be a co-extruded layer or blended with other polymers. The oxygen scavenging polymer is activated by ultra-violet light prior to installation by a form fill seal apparatus. This zipper is particularly useful in reducing residual oxygen in the packaging of such food products as cheese and meat, thereby extending the shelf life.
