Modified Atmosphere Packaging (MAP)

Gas flush (optional)

Prior to the seal phase, a gas or nitrogen can be added. KUNBA vacuum packaging machines can be equipped with the option Gas flush or Modified Atmosphere Packaging (MAP).

It depends on the product which gas is most suitable. Your supplier can inform you best which is the optimum composition for your application. Please contact us with your specific gas requests.

N2, CO2, O2, Ar

Gas mixture

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).
