Modified Atmosphere Packaging

As soon as it comes into contact with air, the color, appearance, texture, taste and shelf life of food start to deteriorate. Modified atmosphere packaging, or MAP, helps to slow down these changes. Air Liquide has developed a special range of products and solutions for MAP applications and has the expertise its customers need to keep food products fresh and safe.

Modified Atmospheric Packaging at a Glance

Modified atmospheric is a process for packaging food products together with a gas or gas mixture that replaces air inside the package and provides protective and reactive properties. When combined, the gas and the packaging help to prevent microbial, enzymatic and physical deterioration in order to maintain the initial taste and quality of a food product. MAP preserves the color, appearance and organoleptic properties of food during the product's shelf life, and protects food from harmful bacteria.


"Air Liquide’s gases help us to reliably extend the shelf life of our products."

Modified atmosphere packaging replaces ambient air with other gases. This allows us to protect our food products from oxygen, which can degrade food quality over time. This also means we can maintain the freshness and hygiene of our products for our customers, while also making them easier to distribute and market.

Air Liquide provides the gases for the protection of our fresh and precooked products. They also work with us to identify the technical characteristics and constraints of gas mixtures and to design packaging based on the individual needs of each product. In this way, we can provide high quality foods in packaging that offers perfect product visibility and presentation.

The control of food products is highly regulated, and it is important for us to maintain the quality and traceability of our foods. Air Liquide gives us all the necessary elements to establish the identification of each and every batch used. Air Liquide also operates quickly and thoroughly to help us perform our product tests as efficiently as possible to ensure safe storage.


Our Gas Solutions

Air Liquide offers a range of food grade gases. As the industry benchmark, our ALIGAL™ gases meet HACCP (Hazard Analysis Critical Control Point) standards for production and logistics of gases dedicated to the food and beverage industry. HACCP is a system which identifies, evaluates and controls hazards which are significant to food safety. Our ALIGAL™ gases adhere to strict quality specifications and go beyond standard regulatory requirements. This ensures traceability along the gas supply chain.

We leverage our historical know-how in MAP applications to work closely with our customers in determining the right gas mixture for their products.
