scientific testing can help us answer this question. In the test of the lunch box conducted by Beijing physical and chemical analysis and testing center, the staff soaked the sample of the lunch box in n-hexane and acetic acid solution for a period of time, took it out, evaporated the solution, and weighed the weight of the remaining residue, so as to determine how much substance in the lunch box may be dissolved in the food. Among them, n-hexane simulates edible oil and acetic acid simulates vinegar, which are common ingredients in daily packaged foods. Ideally, disposable lunch boxes should be made of high-purity polypropylene plastic. This is a translucent round particle like rice, with high flexibility and high temperature resistance. It will not react chemically when immersed in n-hexane and acetic acid solution. However, in actual production, people will add a certain proportion of calcium carbonate and talc powder to pure polypropylene as “filler” other than the main material. In nature, the most common state of calcium carbonate is “stone”, and in the raw materials produced in factories, because of its higher purity, its shape becomes as thin and short as small chalk. It is precisely because of their addition that the color of some disposable lunch boxes has changed from transparent to white. According to national regulations, the proportion of filler in raw materials shall not exceed 20%. But the fact is that the proportion of calcium carbonate in raw materials of some manufacturers is more than half, and some “even more than 80%”. However, only these powder like chalk can’t make a flexible and waterproof lunch box. Therefore, workers also need to add paraffin and industrial waste plastics as supplements to the raw materials. Among them, paraffin is a white solid block like a candle, and industrial waste plastics are small brown particles. If you get closer, you can smell a pungent smell. The sources of these industrial waste plastics may be leftover materials produced by factories, recycled old plastics, and even medical waste. They are mixed together, melted, extruded into strips, and then cut into fine particles. This was originally a raw material that was not allowed to be used in the food industry. Finally, it was made into a lunch box, filled with meals and sent to us, and even eaten into our stomach. Dong Jinshi said that according to the test results, the substances dissolved in acetic acid and n-hexane solution include “some carcinogenic components in industrial calcium carbonate and industrial paraffin”. This is the ingredient of the lunch box we “eat”. Among these components, industrial calcium carbonate may affect the metabolic system of human body, form gallstones and kidney stones, and the heavy metal impurities contained therein will also threaten the health of human digestive tract and nervous system. As for the polycyclic aromatic hydrocarbons contained in paraffin, they will affect the human hematopoietic system, nervous system and digestive system, accumulate toxicity and induce cancer. China consumes 15 billion disposable lunch boxes every year, and the “qualified rate is less than half”. Nowadays, it is not easy to avoid such “black heart lunch boxes”. As the Secretary General of the International Food Packaging Association, Dong Jinshi said that the “pass rate” of disposable lunch boxes on the market is less than half. For the calculation process of this proportion, Dong Jinshi explained that only about half of the manufacturers producing lunch boxes in China have obtained industrial and commercial and health licenses. In his daily investigation, he found that some enterprises will restart the illegal production of unqualified products after obtaining the license. More importantly, in the actual sales, unqualified products occupy most of the market share. This market situation once again affects the data of qualification rate. “Profit is the only problem.” Dong Jinshi thinks. He calculated an account: if the production of high-quality lunch boxes and the use of food grade polypropylene resin raw materials, the price per ton of raw materials would be 11000 yuan. The price of industrial waste plastics is 5000 yuan per ton, and low-quality industrial calcium carbonate filler is cheaper. It only costs 2000 yuan per ton. After conversion, the cost of black heart lunch box can be saved by half, and there is more profit space. Although in terms of quality, high-quality lunch boxes have incomparable advantages: because of the high purity of polypropylene, such lunch boxes are strong, non leakage and low harm to health. Dong Jinshi even made up a doggerel to explain how to distinguish poor quality lunch boxes: “touch soft, tear it gently, break it, smell pungent and choke your eyes, deform and leak in case of heat, sink in the water when it is cut, and white marks will appear when it is folded…” but for consumers who buy lunch boxes – hotels, compared with quality and safety, Price is often the most important factor they consider. As a result, low-cost low-quality black heart lunch boxes have gained the upper hand and occupied most of the market share again and again. Dong Jinshi can’t help complaining that the market in Beijing is “almost monopolized by rotten lunch boxes”. He has seen the production process of “black heart lunch box” in many cities. In Tongzhou District, Beijing, in a small smoky factory, the environment is dirty and messy, and the air is full of pungent and strange smell. “An enterprise that doesn’t even get a license, of course, won’t pay attention to sanitary conditions.” According to the data released by the International Food Packaging Association, China consumes 15 billion disposable lunch boxes every year. According to the pass rate estimated by Dong Jinshi, this means that more than 7.5 billion “black heart lunch boxes” are consumed every year. Food packaging is not food, but the production standard should also be the same as food. Since the proliferation of counterfeit environmental protection lunch boxes in 2001, Dong Jinshi has devoted himself to the cause of exposing the “invisible poison” of food packaging. Up to now, he has adhered to it for 10 years. However, it is the first time for him to resort to law for quality problems like this year. “No way, because other methods really don’t work.” Dong Jinshi said. At the beginning, he would complain to the quality supervision department, but the other party always advised him to wait first because he was “too busy with more serious quality problems”. Later, he began to find the media, pull reporters to make unannounced visits and expose them together. But when the reporter left, these factories will start again. Before that, they were “busy for nothing”. Dong Jinshi found that although it was not too difficult to distinguish the “black heart packaging” of poor quality, people didn’t pay enough attention to the safety of food packaging compared with the food directly eaten into their mouths. “Food packaging is not food, but its production standard should be treated as food.” Dong Jinshi said. He has seen some factories smash waste optical discs, wash them with sulfuric acid and dry them in the air. During this period, the workers will step around barefoot on the ground drying plastic fragments. Finally, these plastic fragments are made into baby bottles. Even, he once found blood stains left by sanitary napkins in the pulp pool in a factory that recycled pulp to make disposable paper cups. At the end of last year, the Ministry of health and other seven departments issued the notice on cleaning up food packaging materials, which clearly stipulated the “list of substances that can be used in food packaging materials” and “list of substances prohibited from being used in food packaging materials”. This once made Dong Jinshi excitedly evaluate as “the earthquake of the packaging industry”, but now he found that many factories still insist on producing “black heart packaging” under the pretext of “not heard”. Even the industrial and commercial and quality supervision departments in some areas s
hirk their “ignorance”. The graduate majoring in environmental chemistry of the Chinese Academy of Sciences gradually realized that these illegal factories were far more complex than the environmental knowledge he had learned. Sometimes, when the front foot inspector leaves, the rear foot factory continues to start construction; Sometimes, because someone “informs”, the law enforcement team will be blocked at the closed gate of the factory. The sound of production inside can be heard, but it just can’t enter the door. “To really promote food packaging, we should not only improve the law, but also ensure the implementation of the existing system.” Dong Jinshi said. According to his vision, this requires further investment from the state and joint action by the departments of health, quality inspection and industry and commerce. In fact, as the Secretary General of the International Food Packaging Association, Dong Jinshi’s efforts are not selfless. His member companies often complain that qualified tableware can’t be sold at all, and the profit margin is too small. He repeatedly reported the factories of black heart tableware. One of his purposes is to find the crowded market for these member enterprises. He will also strive to promote through the media, hoping that everyone will buy food packaging with certified quality: “QS” mark representing food quality and safety market access, number representing plastic category, and a triangular symbol representing recyclable. Only with these three symbols can we be qualified products. ” On March 20, after an interview, Dong Jinshi asked the waiter of the cafe for packing. When the lunch box was brought, he habitually looked at the logo at the bottom of the lunch box: there was no QS certification, there was no plastic variety logo, and there were only two letters “WD”. Dong Jinshi said that this was usually the abbreviation of the name of the manufacturer. “Typical fake and shoddy products.” Dong Jinshi looked carefully and smiled, “I know this enterprise. They once said they wanted my leg.” Soon, he turned and asked the waiter to bring some more lunch boxes, and then carefully put away the “evidence” he had just got. “When this lawsuit is decided, I’ll sue this hotel again. Come a few more times, maybe the industry will be better.
