In the food or medical packaging industry, using multi-layer coextrusion plastic film is a key component to ensuring the safety of the product. In addition, using packaging material that prolongs a products shelf life can drastically cut down on waste of perishable products, and creates a longer window for grocery stores to stock product before it reaches the hands of the consumer. A great way to achieve this is by using a packaging material that reduces the amount of oxygen that permeates the plastic, such as EVOH, incorporating the material into multi-layer coextrusion structure.
