What should we pay attention to when using vacuum bag packaging?

Many customers reflect that they do not know enough about the use of vacuum bags, so we specially ask vacuum bag manufacturers to introduce this knowledge for you, and hope to help you.

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

1, food vacuum packaging bag at the factory is no smell, no odor, with special smell of food vacuum packaging bag, can not be used as food packaging bag.

2, the color of the vacuum packaging bag (the current market with dark red or black and other colors) can not be used for food packaging. Because such vacuum bags are often made of recycled plastic.

3. The outer packaging of the food vacuum packaging bag should have a Chinese logo, mark the factory name, factory address, product name, and indicate the words for food in the obvious place. Products are accompanied by product inspection certificate after leaving the factory, this kind of food vacuum packaging bag is better.

4, try to choose food vacuum packaging bags without coating and coating. In modern packaging design, in order to make the packaging more beautiful and corrosion resistant, a large number of materials with plating are used. This not only brings difficulties to the recycling and reuse of materials after the product is scrapped, but also most of the paint itself is toxic.
