Chemical Manufacturing – Barrier Coatings

SNP Barrier Coating Packaging

Barrier coatings are functional coatings which reduce or eliminate the flow of a fluid. These coatings have been used to control the flow of oil and grease, water, moisture (water vapor), oxygen, and other fluids. The ability to control these fluids is useful in many applications, especially packaging.

Types of Barrier Coatings

There are many different types of packaging utilizing barrier coatings. Some types of packaging are pharmaceutical, cosmetics, liquid, and many different food types. Barrier coatings can provide protection and may increase the shelf life of products.
