Barrier packaging: Novel material and process solutions
from By Don Rosato
With new plastic barrier materials, let's start by taking a look at layered barrier film material comparisons. It is vital to provide food packaging protection with proper barrier components to ensure product shelf life. Some products are susceptible to moisture, oxygen and/or other gases. Barrier films often consist of multilayers or coated films designed to be impervious to gas and moisture migration as single-layer films are in general quite permeable to most gases.
