Vacuum bags, also known as vacuum packaging, are based on the principle of
atmospheric pressure. The main function of food vacuum bags is oxygen to help
prevent food spoilage or deterioration. Vacuum packaging is a process in which
food packaging bags and oxygen are pumped out of the cells, resulting in the
loss of microorganisms in the 'living environment'. Vacuum food can prevent
oxidation, make food unpleasant, and reduce the loss of vitamin A and C when
spoilt.
Vacuum bag
Food vacuum bags can play an important role in reducing risks in safe
transportation. Packaging bags can also prevent food from reaching other goods.
It is possible to reduce the amount of food packaging that can be eaten
secretly. Some food packaging is powerful and has anti-counterfeiting markings
to protect the interests of businesses from losses. The package can have laser
marking, special colors, and message authentication labels. Other retailers come
to prevent theft by demagnetizing food packaging bags with electronic
surveillance labels, such as consumer shopping exports. At present, China's food
quality and food safety market access system is implemented in three batches of
28 types of food.
