Used for packaging food, otherwise it will cause damage to human health.
2. When buying plastic packaging bags, many people are used to picking thick and strong ones, but in fact they are not thicker and stronger. The country has strict regulations on plastic packaging bags, especially the plastic bags used for food packaging, and must use qualified products produced by regular manufacturers and approved by relevant departments. It is necessary to mark the words "special for food" or "QS mark" in plastic bags for food. In addition, you can see whether the plastic is clean in the light.
