Nowadays, many small restaurants cover the bowls with plastic bags, and then serve hot soup. Customers feel that there will be no cross-kissing, and the boss will save trouble. Actually very unhealthy. Preheating the plastic bag (80 to 100 degrees) will not completely decompose, and the high polymer components will be degraded into smaller polymers. We drank it all into our stomachs. Wujiu plastic bag manufacturers remind you that there are two situations after the plastic bag is heated, because there are indeed non-toxic substances.

Generally speaking, colored plastic bags are recycled plastic bags, and the colorants used usually contain benzopyrene, which may be transferred to food after contact with food, causing chronic poisoning. In addition, the latest research shows that the plasticizer in plastic products is also a carcinogen, and because of the poor process and other reasons, the plasticizer of recycled plastic is more likely to seep out when it comes into contact with food, especially oily food, which is more harmful .

The main component of plastic bags is polyethylene, with a melting point of about 120°C. Polyvinyl chloride is a toxic chemical raw material. When encountering acidic and oily substances, especially when the food temperature exceeds 50°C, the toxic components of the plastic bag will seep out and contaminate the food. When the temperature reaches 80°C, it will melt when exposed to heat and release toxic substances. Although this kind of harm cannot be seen for a while, long-term use will definitely cause chronic poisoning and endanger health. Master the skills of identifying plastic bags In daily life, citizens can identify whether food plastic bags are toxic or not through some simple operation skills.

Sensory detection method: the non-toxic plastic bag is milky white, translucent or colorless and transparent, and feels lubricated when touched. Toxic plastic bags are turbid or light yellow in color and feel sticky.

Water detection method: Put the plastic bag in the water and press it into the bottom of the water. The non-toxic plastic bag can emerge from the water, while the toxic plastic bag can sink.

Shake detection method: Grab one end of the plastic bag with your hand and shake it vigorously. The one that makes a crisp sound is non-toxic, while the one that makes a muffled sound is poisonous.

Fire detection method: non-toxic polyethylene plastic bag is flammable, the flame is blue, drips like a candle when burning, and has a paraffin smell. Toxic polyvinyl chloride plastic bags are non-flammable, extinguish immediately after leaving the fire, and emit a pungent smell.
