How to choose food packaging bags?

The chemical composition and properties of different foods are different, and the protection requirements of food vacuum bags are also different. Therefore, professional food production companies must choose the corresponding food vacuum bags according to the nature, shape and production process of the food.

For example, after sterilizing food products, in order to maintain the color, aroma and taste of the food, corresponding food vacuum bags are made, and high barrier properties are required (to extend the shelf life of the food); for example, tea packaging should have high oxygen Barrier property, high moisture barrier property, high light barrier property, high aroma barrier property, otherwise it will cause oxidation, mildew and mildew of the active ingredients in the tea.

The mode of transportation is also a factor in choosing food vacuum bags. For example, a food product may sail and float on the sea for a period of time, and its temperature will increase. Then, the product packaging must be able to prevent all items from the outside world, and the product will not deteriorate.

Since the packaging bag is in direct contact with food, long-term use of inferior food packaging contact materials will gradually penetrate into the food during storage and use, and accumulate in the body and cause chronic poisoning, causing direct harm to consumers.

In addition, improper use of qualified food vacuum bags may also lead to food contamination. For example, using non-heat-resistant food and packaging materials to package high-temperature cooked food may cause chemical reactions in the food and produce toxic substances.
