Recently, reports on plastic packaging, such as plastic bagged foods and plastic bottled water, have frequently appeared. Is it a problem with our plastics, or is it a falsified, counterfeit, or unqualified product that has caused confusion in the market?

Poisonous plastic food bags are not much

Chen Jiaqi, National Quality Supervision and Inspection Center for Plastic Products, told reporters that the plastic bags we use today are mainly polyester, polyethylene, polypropylene, polystyrene, PVC, etc. Among them, polyethylene and polypropylene can be used. To dress food, most PVC plastic bags are toxic and cannot be packaged. Because the unpolymerized vinyl chloride monomer in the polyvinyl chloride resin is toxic to the human body. In the process of processing PVC into plastic bags, polyvinyl chloride has also added plasticizers, pigments and other toxic auxiliary materials. Stabilizers are added to some plastics. These stabilizers are lead stearate and are also toxic. However, Director Chen pointed out that it is very difficult for us to find a toxic plastic food bag, that is, there are few toxic plastic food bags.

As for whether the plastic bags can hold hot foods, Director Chen said that we have done tests. The plastic bags will degrade at 200°C in pure oxygen, and the temperature of heated foods in daily life will not reach, of course, plastic bags. The phenomenon of softening is sure to happen. In addition, if you use a microwave oven to heat food, it is best to use a special microwave oven plastic bag.

It is understood that on December 22, 1997, the capital’s six management departments jointly issued a notice prohibiting the sale (use) of ultra-thin plastic bags. Since January 1, 1998, Beijing farmers’ markets, markets, and commercial The outlets prohibit sales (use) of ultra-thin (thickness below 0.015mm) plastic food, shopping, garbage bags, etc.; plastic bags used for food packaging must comply with the corresponding food packaging materials hygiene standards, plastic bags produced from recycled materials shall not For food packaging, the thickness of the plastic bag used in the production of recycled materials for other packaging needs to reach 0.02mm. Afterwards, a government decree issued by the mayor of Beijing stipulated that since May 1, 1999, plastic bags with a thickness of less than 0.025 mm will be prohibited from being sold and used throughout Beijing, encouraging the use of bags, paper products, etc., to be repeatable. Used shopping bags. However, the actual situation is not satisfactory. This provision has been implemented very well in supermarket shopping malls, but it can no longer be reached by mobile hawkers. A stall owner who sells vegetables said that if customers don't provide plastic bags, some customers will not buy them. If a qualified plastic bag is used, the small profit-making small business would have been done. It is precisely these ultra-thin plastic bags that are accompanied by winds, causing great pollution to the environment.

Some plastic water bottles are made of "garbage"

In June 2001, the Guangdong Provincial Department of Health and the Provincial Bureau of Quality and Technical Supervision seized a large number of drinking water bottles that were used illegally in recycled products in Shunde. According to investigations, this situation that has jeopardized the development of the industry and the health of the people has existed for two to three years, and has become increasingly intensified.

The market share of small and medium-sized cities in Guangdong reaches 40%, and it has spread to large and medium-sized cities. Afterwards, the Guangdong Bottled Drinking Water Association submitted an emergency report to the provincial health department regarding the “ban on the use of waste pellets and non-edible pellets to bottle canned drinking water.” The Guangdong Provincial Health Department immediately issued a document to severely punish the counterfeiters.

It is understood that the Ministry of Health of the People's Republic of China has set strict standards for food-grade plastic packaging containers, and disposable food-grade packaging materials will never be allowed to be recycled for reuse. However, many unscrupulous manufacturers use non-food products such as waste plastic or discs to discard profits. Raw material recycling waste is processed. Such packaging contains toxic chemicals, and the harmful substance “acetaldehyde” dissolves in water. Experts believe that the food packaging made of the above materials damages human nerves, causing dizziness, vertigo, etc. In severe cases, even cancer.

On June 16th, 12 member units of Guangdong Province solemnly promised to the society that they would firmly refuse to use drinking water bottles that do not meet the hygiene standards.

Must resist the wrongdoer

It is understood that China's plastics industry is in a new stage of development, with huge market potential and broad space for development. It is estimated that the market demand for various types of plastics this year will be more than 10 million tons, an increase of about 15% from the previous year. The increase in demand for plastic products includes engineering plastic products, building materials plastic products, packaging plastic products, and agricultural plastic products. The demand for these products is 2 million tons, 1 million tons, 7 million tons, 353 tons, and 2.5 million tons respectively. The largest demand for plastic products.

Due to the large market demand, some lawbreakers have seized the opportunity to make counterfeiting from China. At the Dazhongsi Farmer’s Market, the reporter saw that most booth owners used plastic bags that conformed to the standards. Individual stall owners still mixed plastic bags of various specifications. One stall owner said that the buyers said they needed me. Sell ​​it. It seems that businesses will not refuse to have a business, but also from the source, to close the small workshops that produce banned plastic bags, and no seller will no one use it.

The same is true for bottled or bottled water packaging. The market can be purified only by blocking the sources of counterfeiting. The industry and commerce departments are law enforcers and strict punishment is a must, but we must remind our consumers to strengthen laws and regulations, food safety and health, etc. Knowledge in the field, safeguarding their own interests. Because after all, consumers are far away from the market and find that the problem is the earliest and most relevant to their own health.
