Most of the shopping in supermarkets use plastic bags to package the purchased goods, which are light and convenient to use. However, the plastic packaging bags on the Dongguan packaging material market are often made of different specifications of plastic packaging bags with toxic and harmful raw materials (even the raw materials strictly prohibited by the state) due to the disorderly manufacturers and purchase channels, and some illegal traders are often driven by interests to put them on the food market for use by consumers, although the relevant administrative and law enforcement departments continue to strictly inspect and investigate, However, toxic and harmful plastic packaging bags are still prohibited repeatedly, and there are great hidden dangers in consumer safety.

In order to protect the legitimate rights and interests of consumers, Xinping packaging materials remind consumers that Dongguan packaging materials should correctly grasp the following three simple methods to identify the advantages and disadvantages (toxic and harmful) of plastic packaging bags when using plastic packaging bags.

The first is hand recognition. Qualified food plastic packaging bags are smooth and flexible when touched by hand, and most of those with harsh and sticky feel are unqualified packaging products.

The second is immersion identification method. The qualified plastic food packaging bags will float in the containers containing water, and the poor or unqualified ones will often sink at the bottom of the water.

The third is ignition recognition method. Qualified plastic packaging bags are easy to ignite, showing blue flame, toxic and harmful, and other unqualified plastic packaging bags are not easy to ignite.
