What should we pay attention to when using vacuum bag?

Many customers reported that they didn't know enough about the use of vacuum packaging bags, so we specially asked the vacuum bag manufacturer to introduce this knowledge for you, hoping to help you.

When using vacuum bag packaging, we need to pay attention to:

1. Food vacuum packaging bags are odorless odorless when they leave the factory. Food vacuum packaging bags with special smell cannot be used as food packaging bags.

2. Colored vacuum packaging bags (dark red black etc. used in the current market) cannot be used for food packaging. Because this kind of vacuum packaging bags are often made of recycled plastic.

3. The outer package of food vacuum packaging bag shall be marked with Chinese mark, factory name, factory address product name, the words for food shall be marked at the obvious place. All products are attached with product inspection certificate after leaving the factory. This kind of food vacuum packaging bag is better.

4. Try to choose food vacuum packaging bag without coating coating. In modern packaging design, in order to make the packaging more beautiful corrosion-resistant, a large number of materials with coating are used. This only brings difficulties to the recovery reuse of the discarded materials, but also makes most of the coatings toxic.
