Berry Plastics' nine-layer film protects against moisture and extends the shelf life of products like granola, crackers, pretzels and other moisture-absorbent foods. Each of the nine layers serves a different purpose to maximize shelf life and package integrity, according to Michelle Wilson, director of development. "The film was engineered with a better moisture barrier resulting in a crisper dry food product as it nears the end of the package shelf life, along with easy opening seals allowing convenient access to the food product," Wilson said.
