The multilayer bag made of high-quality PA/PE film guarantees your product one thing in particular: protection – even under high humidity conditions. Depending on the product, different material layers up to high barriers are applied. The multilayer bag’s 5-, 7- or 9-layer structure enables an extension of the shelf life of food and, for example, provides optimum maturation conditions for cheese. The PA- and/or EVOH-barrier layer sandwiched between the PE-layers is geared exactly to your product, preventing external oxygen from influencing the ripening process of cheese and, at the same time, allowing the resulting CO2 gases to escape.
