Option: Gas injection

After vacuum packing and before the bag is sealed, there is an option to add gas. This is often used to extend the shelf life, as extra protection for fragile products and to prevent discolouring of specific products.


Examples of products where gas injection is useful are: chopped lettuce, salad leaves, minced meat, steak, cooked fish, pre-baked products, crisps and ready to use products. It depends on the product which gas mix is most suitable. Your gas supplier can inform you best as to the optimum composition. A special oxygen (O2) pump is available for gas mixtures of more than 20% oxygen (O2).
