Modified Atmosphere Packaging (MAP)

Controlling the atmosphere around a food product is key to extending product shelf life and maintaining an attractive customer presentation. Our experts understand the importance of gas flush packaging, a process that replaces package headspace with a beneficial gas or mixture of gases that will dramatically slow bacterial growth and oxidative reactions.

With Modified Atmosphere Packaging (MAP), longer quality shelf life results in fewer product returns, less waste and higher customer satisfaction, and allows for optimization of production and distribution. With many decades of experience in the food industry, Air Liquide was one of the first to gain patents in modified atmosphere. Our food industry experts understand that packaging material and equipment is every bit as important as the right mixture of gas. Our teams are in the field providing on-the-spot expertise for gas packaging of meat, poultry, fish & seafood, fruits & vegetables, baked goods, prepared meals, cheese and dairy products.



Our food specialists will work closely with you to develop customized MAP solutions for your operations. We offer a range of services including process analysis and optimization, product tests, installation and start-up support, inspection and maintenance.
