What should be paid attention to when using vacuum packaging plastic bags?

　　1. The outer package of vacuum packaging plastic bag must be marked in Chinese, indicating the factory name, address, product name, and the word "food". When the product leaves the factory, it is attached with the product inspection certificate. This vacuum packed food plastic bag is safer.

　　2. The color plastic bags of vacuum packaging cannot be used for food packaging. At present, they are dark red or black in the market. Because such vacuum packaging plastic bags are often made of recycled plastic. Not very safe.

　　3. The vacuum packaging plastic bag shall be free of peculiar smell and odor when leaving the factory, and the vacuum packaging plastic bag for food shall not be used as the food packaging bag. In addition, there is another flavor that is recycled. Who knows what was previously packaged, especially food packaging.

　　4. Food vacuum packaging plastic bags shall be selected as far as possible, instead of uncoated and coated plastic bags. Because of the modern packaging design, many enterprises use a large number of materials with coating in order to make the packaging more beautiful and corrosion resistant. This situation not only makes it difficult to recycle and reuse waste materials, but also most of the coatings themselves are toxic. If people eat food packaged in food, it will cause great harm to people's health.
