What is Modified Atmosphere Packaging, MAP?
Everyone knows that food does not stay fresh forever. Milk turns
sour, bread goes mouldy, meat develops a brown colour and an ‘off’
smell. A number of factors cause food spoilage. Oxygen in the air
can cause a process of decay called oxidation. For example fats and
oils in food can oxidise to make the food turn rancid. One of the
main causes of the spoilage of food is the growth of microbes such
as bacteria, yeasts and mould that are present all around us, even
in and on our own bodies. These microbes feed and grow on the food
product, causing it to go bad. The appearance of food can also
change over time when exposed to air. Fresh meat turns brown after
a while because of interactions between oxygen and pigments in the
tissue.
There are a number of ways to slow down these processes of spoilage
and to keep food attractive and edible for as long as possible.
These include simple refrigeration – the lower the temperature the
slower most microbes will grow – or treatments such as pickling,
curing with salt or by adding artificial preservatives.
However, to keep food fresh for as long as possible without
additives is a challenge, and one key technology for achieving this
goal is to seal the food product in a package which contains a
mixture of natural gases in carefully controlled proportions that
significantly slow down the process of decay by inhibiting
processes of oxidation and the growth of microbes. This is the
essence of modified atmosphere packaging: the atmosphere in which
the food is packaged is modified so that spoilage is markedly
reduced and the shelf life of the product is increased.
The type and proportion of gas used in the packaging is largely
dictated by the type of food in the package and the sort of decay
or change that the food undergoes.
To package a product in a modified atmosphere requires
sophisticated machinery to flush out air from the packaging chamber
and replace it with a different gas or precisely defined mixture of
gases, then seal the product in the packaging so that only the
modified atmosphere surrounds the product and not any other
unwanted gas.
What products use MAP?
MAP is commonly utilized in snacks, coffee, cheese, pasta, baked
goods, sandwiches and processed meats. It is also becoming
increasingly popular in fresh-cut produce, like pre-packaged salads
and fruit, for convenience, quality and more variety.
Chances are, if you’re shopping for any of these items at the
grocery store, they’ve been packaged using MAP. Learn more about
this growing packaging trend when you reach out to an Atlas Copco

Devices maintenance
1. Keep the touch screen interface clean, and oil stains will
greatly damage the touch screen. When cleaning the surface, shut
down and power off, and gently wipe the surface of the touch screen
with a dry cloth. During normal operation, pay attention to
moisture, dirt, scratches, and bumps.
2. During the long working process, the upper mold heating plate
for heating and sealing may have dirt on the sealing surface, which
will affect
the quality of the sealing. It should be cleaned regularly
according to the situation: gently rub the dirt with a cloth and a
little detergent.
3. During the long-term use of the cutter for film cutting, there
will be film remaining on the edge, which affects the film cutting
effect, and should be cleaned regularly according to the situation.
4. In order to avoid water ingress into the electrical system of
the equipment, leading to unpredictable consequences, it is
forbidden to directly flush the equipment with water. The correct
method is to gently wipe the dirt with a cloth and a little
detergent.
5. Due to the compressed air itself, some water vapor will enter
the decompression filter valve, and it should be drained regularly.
6. Regularly apply a small amount of food-grade grease to the
chain, taking the obvious drop as a reference.
