Suitable for the food and nonfood sectors, film is designed for use with sharp-edged, confectionery, and meat products. For example, individual meat portions can be packed in the low-barrier Clysar and then sealed in a tougher, outer barrier pack for transport to the retailer. As soon as the outer pack is removed in the supermarket, the meat portions are oxygenated and take on a fresh red color.
