In which volume can I buy ALIGAL™ 15 gas mixtures for foods?

Buy 50/50 Nitrogen-CO2 gas mixture in the quantity that you need : from single small gas bottles, to bundles (package of 9 to 16 cylinders) up to a separated liquid storage tank with a gas mixer, delivering the right flow to your packaging machine.

Why choose ALIGAL™ 15 gas mixture composed of 50% N2 & 50% CO2?

Food manufacturers have known and feared one of their biggest “enemies” for years: Air contains oxygen and promotes the development of bacteria and microbes and causes various damage to the foods: change of color, texture, taste, and has an impact on the shelf life. To avoid these effects, Air Liquide offers a solution: the packaging in a protective atmosphere (also called "gas packaging" or MAP). The solution is to replace the air in the packaging with an alternative gas composition, which can extend the organoleptic properties, nutritional value and shelf life of the product.
