What is Barrier Packaging?

Barrier packaging is designed to limit the movement of substances such as oxygen, moisture, light, aromas, or gases through the package. Barrier performance is particularly important for food, pharmaceuticals, chemicals, and moisture-sensitive products. Packaging may use specialized films, coatings, foil, or multilayer structures. The required barrier level depends on the product's sensitivity and intended shelf life. Proper barrier selection helps maintain product quality during storage and distribution.
