We sometimes get questions about the types of materials we use when making flexible food packaging. Although we can make bags with materials suited for packaging everything from detergents to organic granola, we always use FDA approved materials. In addition, the only materials that touch food products are FDA approved food grade films. Our pouch bags can be made of several layers, but the only one that touches the product is the inner layer.
The first, or outer, layer of the bag has barrier properties, puncture resistance, and is stronger than other layers that make up the bag. The next layer is the second or inner layer. This part of the bag is where the printing goes and is thus very thin and not used for strength. It does have some barrier properties but it is mostly used to show the crisp graphics of our custom printing.
Depending on the product, other layers can also be present, but the inside film is always going to be the food grade layer because this is the only part of the pouch bag that comes into contact with the product. This combination of laminated layers results in stand up pouch bags that make use of barrier films and beautiful, professional printing for strong, high quality stand up packaging.
