Barrier Films

In the food industry, using packaging which extends the shelf life of a product is extremely beneficial as it helps to ease pressure on the supply chain and maintain the products quality for longer.

Alert Packaging's high barrier films provide a flexible solution for the preservation and protection of products and can be used in combination with, of independent of, MAP (Modified Atmosphere Packaging) and CAP (Controlled Atmosphere Packaging). Using these techniques helps to significantly improve a products shelf life.

The CAP and MAP processes are extremely similar however, with MAP, the gas concentrations may change following sealing as a result of the use of oxygen and expulsion of carbon dioxide. With CAP, the gas concentrates remain the same due to the use of gas-impermeable packaging which may be metalised polyester or foil. Baby food and coffee are two products which benefit from this process.

Barrier films from Alert Packaging can also be used to produce bags and pouches for products which suit an simpler handling process. The alternative packaging provides a more effective solution for storage and shipping compared to cartons or tubs and improves food safety by significantly reducing the possibility of cross-contamination.

The barrier film pouches can be customised to suit a required size and because it is dual function packaging, can be used for products which require microwaving and cooking.

The flexible lidding films can be applied to preformed and thermoformed bases and feature characteristics such as Easy Peal or Anti-fog for good clarity windows which provide end customers with a convenient packaging product.

The Lidding Films from Alert Packaging provide a fast packaging solutions with uniform sealing and superior seal integrity. An effective oxygen and moisture barrier is also present preserving the quality of the product and extending shelf life.
