Modified atmosphere packing (MAP) packs are produced by evacuation and gas flushing. This combination gas usually consists of carbon dioxide, nitrogen and oxygen.
A gas flushing for modified atmosphere is incorporated prior to heat-sealing of the container.
Combination gases as follows is very often used
Oxygen (O2): in high concentration inhibits the growth of aerobic microorganisms.
Nitrogen (N2): mainly used as a stabilizing gas to maintain the pack volume for protection during handling or as transportation packaging.
Carbon dioxide (CO2): reacts with water to form carbonic acid, which helps to lower the PH. This atmosphere inhibits the growth of micro-organisms.
In the case of fresh meat and poultry, fresh pasta and baked products, and fresh-prepared foods, the modified atmosphere compliments refrigeration to retard chemical and/or microbiological deterioration of the food.
Packaging many fresh fruits and vegetables in a modified atmosphere with selected low oxygen content and elevated carbon dioxide content reduces respiration, with resulting increase in shelf life.
MAP Packing Machine need to prepare the tray container in advance, this is diffrent to the thermoforming vacuum packing machine.
|Maximum film width||560mm|
