Worrying food plastic bags

Since its invention in the 20th century, food plastic bags have been accepted by consumers because of its convenience, and have penetrated into every aspect of life, becoming an indispensable part of the fast-paced, high-efficient life of consumers: supermarket shopping, trade The market buys vegetables, and in the morning, it is natural to buy fritters, taro, and the purchase of cooked food and dry food. Although everyone may have heard about the harm of some shoddy plastic bags, there are still many people who are lucky enough to believe that the damage is really so great. Then let's take a look at the relevant situation and see if it is serious.

1: What kind of food packaging bag should be qualified food plastic bags in accordance with the national health standards of food plastic particles as a raw material by adding certain plasticizers, stabilizers and other additives through the extrusion, blow molding, molding and other processes. to make. Food packaging bags of normal and regular channels shall be produced according to the “Hygiene Management Methods for Food Plastic Products and Raw Materials” and “Food Sanitation Law” of the Ministry of Health of the People's Republic of China, and shall be produced only after strict examination by the health supervision department. When a plastic bag for food is delivered from the factory, the outer package must have a Chinese logo, the name of the factory, the address of the factory, and the implementation standard. The word “used in food” should be clearly marked and the product inspection certificate should be attached after the product leaves the factory. The food production and operation units that use food packaging bags must obtain a copy of the production hygiene license and inspection certificate from the plastic bag manufacturing company for inspection. Currently qualified countries allow raw materials used to produce food bags: polyethylene, polypropylene, polyester, polyamide, polyvinylidene chloride, polycarbonate, polyvinyl alcohol, ethylene-vinyl alcohol copolymer, etc. Adapt to the needs of packaging various foods. In terms of food hygiene and safety, raw materials meet national standards and production processes are strictly controlled. Their products are safe to the human body and can be used with confidence.

2: Existing problems With the reform and opening up and the operation of the market, the rapid economic development, and the acceleration of the pace of life, the high convenience of plastic bags has become more prominent, making its demand more and more. The production process of plastic bags is relatively simple and the first phase of investment is very small, so there are quite a number of unlicensed home-style workshops or individuals have the ability to invest in the production of various plastic bags. In order to reduce the cost, the raw materials used by these small factories are often various kinds of waste plastics recovered from garbage stations, and even medical infusion needles, pesticide bottles, and agricultural plastic films. Chemical additives are added to make vest bags, that is, recycled plastic bags. They sell them to small business hawkers via wholesale or street walks, even to some big shopping malls, big food stores, and finally reach consumers. It is understood that this type of recycled plastic bag occupies a large share in the market due to its low price and great market competitiveness. There are many delicatessens, restaurants, and shopping malls that have previously used regularly-qualified food plastic bags. They are also quietly using or mixing recycled bags.

Nowadays, the problem of using more and more widely used recycled plastic bags has surfaced and it has begun to attract everyone’s attention. This recycled plastic bag is used to package foods. The harm to the human body is hidden, long-term, chronic, and can cause some acute and chronic diseases and even cancer.

The source of raw materials for the production of recycled plastic bags is extremely complex, inevitably containing polyvinyl chloride components that cannot be used for packaging food, or containing other unknown poisons and a large number of microorganisms and germs that are invisible to the naked eye. Food, the harm to human health is extremely great. In the process of processing waste plastic raw materials into recycled plastic bags, plasticizers and plastic stabilizers such as lead stearate are used. Due to the simple process of recycled plastic bags, these reusable plastic bags are used to hold oily, alcoholic foods and the temperature exceeds 60. °C foods, bags of monomer, lead, etc. are easily dissolved into the food, can easily cause people to accumulate toxic, causing great harm to the human liver, kidney and nervous system. Recycled plastic bags in the production process to cover the raw material impurities and add coloring agents, so the common variety of colorful plastic bags. Its permeability, volatility, when exposed to oil, hot, easy to seep out. If it is an organic colorant, it also contains strong carcinogens such as benzopyr, and the contact with food is transferred into the food, causing harm to the human body.

3: Introduction of Toxic Substances in Plastic Bags of Inferior Quality Foods PVC: When polyvinyl chloride monomer is absorbed in the gastrointestinal tract, part of it is discharged through the respiratory tract and the other part is decomposed into ethanol and monochloroacetic acid. These substances can have toxic effects on the nervous system, bones and liver, leading to the occurrence of angiosarcoma. Ethanol can damage human nerves, causing dizziness, vertigo, and even serious cancer.

Lead stearate: Lead stearate is a stabilizer for polyvinyl chloride plastic bags. Lead at high temperature will dissolve into the foodstuff. Lead stearate is easily precipitated and it can cause accumulated lead poisoning once it enters the body. These toxic substances are eaten with food and are harmful to human health.

Phthalates: Phthalates, called phthalates, are additives for plastics processes and are mainly used to increase the flexibility of plastic products. A small amount of human exposure can be detrimental. Phthalates are low-toxic chemicals that damage the central nervous system and liver. Plastic processing technology will not be used in large doses, and phthalates must be free to release toxic monomers when heated at high temperatures. Qualified plastic products will not cause any harm to the human body. The hazards exist in the production process. .

Compounding agents: In order to increase the transparency and elasticity, a certain amount of plasticizer is added to the PVC cling film. After a long time of wrapping, the oil in the food easily dissolves the harmful substances in the cling film, and when heated, the combined chemical agent in the plasticizer is accelerated into the food. These compounds will destroy the body's endocrine system, disturb the normal hormone metabolism of the human body. After eating, it will cause women's breast cancer, birth defects in newborns, reduced sperm count in men, and even mental illnesses.

After reading the above, I wonder if everyone understands the dangers of inferior plastic bags? In daily life, we should try to avoid contact with our food. Do not use plastic bags for breakfast and vegetables. It is best to bring your own lunch box or green bag. For our health, don’t be afraid of trouble!
