Plastic bags have strict standards, especially those used for food packaging. We must choose regular bags manufacturer to produce. Qualified products approved by relevant departments will guarantee the quality of these bags.

Plastic bags for food must be marked with the words "for food". Looking at the light, you can see whether the plastic is clean or not. Qualified plastic bags are clean and free of impurities, while inferior plastic bags can see dirty spots and impurities. The thickness of one side of plastic bags must be above 0.025mm, which is not up to this thickness. The state prohibits production and use.

Many deep-colored plastic bags are often made from recycled waste materials, which do not have direct access to food.

(3) Reuse of plastic bags. Many families have the habit of storing waste plastic bags. In fact, as long as we pay attention to tidiness and the use of waste plastic bags, it is possible to store them. However, we should not use waste plastic bags to contact food and skin, which will cause chronic harm to our health.
