What is a Barrier?

A barrier is a function of the film. It prevents oxygen, moisture and other substances from penetrating the film that may alter or deteriorate the quality of its contents. It is one of the most important functions of packaging or protective materials, and often extends the shelf-life for products that incorporate it.
