A barrier pouch is a packaging format that contains non-permeable materials which result in low moisture vapour transmission rate (MVTR) when sealed correctly. Typical materials include the likes of aluminium, PET, PE and OPP usually in combination to form a multi layered flexible packaging.
The low MVTR rate drastically lowers the products exposure to moisture, air, light, gas ingress and other environmental hazards that could potentially deteriorate and damage the product.
Barrier pouches are designed for long term asset preservation during transport and storage. Protection can often be further enhanced with the addition of other consumables like Silica Gel and Oxygen Absorbers. When used in conjunction with heat sealer machines and other sealing procedures, barrier pouches are a great way of protecting a wide range of products.
