Bemis Company, Inc: Box liner films allow 30% downgauging

The films allow makers of boxed cereal, baking mixes and other moisture-sensitive dry foods to use liner film at gauges as low as 1.5 mil. The high-clarity, HDPE-based films offer superior moisture and oxygen barrier to protect food quality and extend shelf life.  Because the films need significantly less material to protect dry foods, they require less energy to produce and fewer truckloads to ship. Other cost advantages include a lower price per MSI than traditional liner films and more footage per roll.
