Gas flush (optional)
Prior to the seal phase, a gas or nitrogen can be added. Henkelman vacuum packaging machines can be equipped with the option Gas flush or Modified Atmosphere Packaging (MAP).
Injecting a gas increases the product's shelf life, it offers extra protection and it prevents the product from colouring. Usually, a mixture of nitrogen (N2) and carbon dioxide (CO2) is used. Dioxygen (O2) can also be added to this combination. The use of argon (Ar) has been increasing, as this contains the same properties as nitrogen (N2).
