Aluminum foil bags in food vacuum packaging bags must be treated by vacuum preservation. Aluminum foil vacuum packaging bags should be selected as green environmental protection materials. On the one hand, they are clean and hygienic, on the other hand, they can maintain the environment.

Especially in aluminium foil vacuum packaging bags, now the general food packaging bags. Vacuum bag is a common kind. The reason why many businesses choose vacuum bags as food packaging bags is because of convenience. Aluminum foil vacuum bags, nylon vacuum bags and so on are rare, but vacuum bags may bring toxic substances in the heating process. Therefore, when using vacuum bags as food packaging bags, more careful choices are needed. Here I need to pay attention to three aspects:

Vacuum packaging bags should not be heated in microwave oven. In life, first of all. It is unreasonable for packaging manufacturers to directly heat microwave oven products with vacuum packaging bags for convenience.

Normal vacuum bags are not suitable for keeping fresh in refrigerators. Ordinary vacuum bag can not achieve the effect of preservation because of its air-tight, secondly. Over time, bacteria will also breed, affecting the health of life.

Vacuum packaging bags are widely used in daily life. Everyone knows that the ability of vacuum packaging bags to protect commodities mainly comes from vacuum. Without vacuum protection, commodities are easy to decay, especially food, which can not protect food. If it is reused, it needs not only the help of vacuum pump, but also the help of heat sealing equipment, which is not available in the family.

I. The Quality Assurance of Food Vacuum Packaging Bags is Important

For food production and marketing enterprises, unqualified food vacuum bags can not protect food safety and hygiene, which is not conducive to the storage and transportation of food. At the same time, unqualified food vacuum bags will also affect the quality of food, such as color, fragrance and taste, which is not conducive to food marketing. For ordinary consumers, unqualified food vacuum packaging bags can produce toxic substances to contaminate food and cause damage to the health of consumers. Therefore, the quality of food vacuum packaging bags is very harmful, in the production process, plastic bag manufacturers should strictly control the quality, improve the quality of food vacuum packaging bags.

2. What Food Suitable for Vacuum Food Packaging

Not every kind of food is suitable to be packed in food vacuum bags. Some fresh food and bulk food do not need to be packed in vacuum bags. Only the function of carrying and packaging can be used.

Food vacuum packaging bags are suitable for packaging foods that are perishable and deteriorating at normal temperature and pressure, such as meat, pickles and other foods. Liquid milk also needs vacuum storage. These are all foods that need to be stored in food vacuum packaging bags.

Vacuum packaging bags can also be used to package non-food products, such as electronic products, and such products do not need to have hygienic grade bags.
