A Guide to Barrier Films: Protecting Your Product from the Inside Out

Not all packaging films are created equal. Learn the differences between clear, white, and metallized barrier films.

Barrier films are what stand between your product and the outside elements — moisture, oxygen, UV light, and odors. Choosing the right film is critical to maintaining freshness, flavor, and shelf life.

Clear High Barrier Film provides excellent product visibility while still offering strong protection against moisture and oxygen. It's a great choice for products where customers want to see what they're buying.

White High Barrier Film offers a clean, opaque backdrop for vibrant printed designs. It provides the same barrier protection as clear film, with the added benefit of blocking light — ideal for products sensitive to UV exposure.

Metallized High Barrier Film delivers the highest level of protection. The metallic layer reflects light and provides superior barriers against moisture, oxygen, and odors. It's the go-to choice for coffee, cannabis, and products requiring maximum freshness.

All three films are food-safe, FDA-compliant, and available across our full range of pouch sizes.
