What is Multilayer Barrier Packaging?

Multilayer barrier packaging plays an essential role by combining multiple layers (between 3 and 12) of different polymers and exploiting the distinct mechanical and physical features of each material to create a perfect and adequate food packaging. Multilayer packaging is the product of the co-extrusion process, which provides skin protection for food, including resistance against puncture, tear, heat, moisture and oxygen. Multilayer barrier packaging protect products from tampering, contamination, or physical damage. The preservation of food products reduces the waste of energy, water and materials used in food production.

Materials in Multilayer Barrier Packaging

Polyethylene (PE), polypropylene (PP), Polyester and Polyamide (Nylon, PA) are the most common materials in several industries. Polyethylene is widely used because it offers cost-saving benefits and can be merged easily with materials that offer gas and aroma protection like Polyamides (PA).

Why Multilayer Barrier Packaging

Multilayer barrier packaging contains properties that safeguard the quality, hygiene and freshness of food products. Again, the environmental and material cost of food production illustrates the need to ensure resource efficiency, derive the value from food products and avoid food waste/loss from the field to households. There is an emphasis on innovative food packaging, which meets the challenges of today’s world and reduce food waste. Performance packaging attracts a high-volume of use in the food and medical packaging industry. The combination of multiple polymer layers significantly increases shelf‐life by regulating the carbon dioxide, moisture and the transmission rate of oxygen inside the package-to retain the freshness of food products for a lengthy period.
