What kind of food packaging bags are qualified

Food packaging bags should be produced using food grade plastic film, usually consisting of two or more layers of composite materials. What are the qualified specifications for food packaging bags? Is your food safe? Let's first check if the food packaging is safe. In fact, whether at home or in the supermarket, we can see some food packaging bags with exquisite designs everywhere.

Food packaging bags are actually the "clothes" of food, not only playing a role in maintaining food, but also closely related to food safety. The food itself requires hygiene and safety, free from impurities, and suitable for the unique sensory characteristics of this type of food. The outer packaging requires the hygiene and safety of the packaging materials, and the packaging should ensure that the food does not deteriorate within its shelf life.

Primary maintenance provides surface maintenance for products, forming a very light and maintainable surface around the product, and then achieving the goals of dust, oil, moisture, waterproofing, and theft prevention. It is particularly important to wrap film packaging to ensure that the packaged items are evenly stressed and avoid damage caused by uneven stress, which traditional packaging methods (such as bundling, packaging, tape, etc.) cannot achieve.

In terms of the current situation of food packaging in China, the approach is not optimistic. Some people believe that the external packaging of food is a "hidden additive." In daily life, many food external packaging may contain toxic and harmful substances, but due to the release and relocation of these harmful substances, most of them are invisible and chronic, and often not detected by people. From the perspective of food safety, harmful substances in the external packaging of food can directly threaten food safety.
