Serious abuse of recycled plastics market
Plastic bags are people's daily life supplies. Not only do they contain ordinary items, most of them are inseparable from it. Daily use of plastic bags can be broadly divided into two types: new plastics and recycled plastics. The former is more hygienic and the latter is non-healthy. Ultrathin plastic bags with a thickness of 0.025 mm or less are used in the food market. It was banned. Frequent use of recycled plastic bags for foods can cause great damage to people and affect people's health. However, recycled plastic bags are still popular in the food market. In the food business establishments throughout the city, it has been found that various flavors, distinctive sesame cakes, steamed buns, oil cakes, fried dough sticks, soymilk, beef noodles and other foods can be sold in plastic bags.
Most of the recycled plastics are synthesized from waste materials such as waste recycling materials and even medical infusion needles. In addition to the unsatisfactory environmental hygiene in the production process, the plastic bags made from it are extremely unhygienic and generally contain a large number of toxic pathogens. . Nowadays, ultra-thin plastic bags made of recycled plastics have entered the market and are used to hold daily necessities, even foods that we want to eat directly. This poses an inestimable safety risk to people's health. For example, buying a hot soymilk at home from a breakfast stall early in the morning, the milk in a recycled plastic bag is hot and the bag melts and produces harmful substances. At this time, if people drink this soymilk, it will cause great harm to the body. .
Why recycled plastic bags and ultra-thin plastic bags with a thickness of less than 0.025 mm enter the food market? This is because the low price of hazardous plastic bags is a direct driver for operators. The average cost of standard food special plastic bags used in some large-scale supermarkets is around 0.008 yuan, while the cost of recycled plastic bags flooded is only around 0.002 yuan. Most operators have not concealed that the use of recycled plastic bags is not conducive to people's health, consumers have also raised questions at the time of purchase, but the free gift of plastic bags has formed a habit in the minds of consumers, if a large number of purchases The special plastic bags for food are used for gifts, and the cost increases virtually. This will lead to a drop in profits. Even some operators disregard the special rectification of the food market. They think that special rectification is just a gust of wind and will be shaved every year. It will not be hard and will not last long.
Avoid illegal use of recycled plastic bags
The production of harmful food bags made of recycled plastics has produced a large number of products and exposed loopholes in the supervision of the industry: Some plastic products small enterprises produce industrial products as well as food products. Therefore, it is recommended that the country establish a plastic food bag production license system. Plastic packaging bags should be marked with “food-specific†or “non-food-use†logos, so as to supervise the strict use of pure raw materials by manufacturers and ensure the health of food bags. . Some places have already implemented this practice and achieved certain results.
As a consumer, you should have at least a minimum of common sense. The dark plastic bags used in the market such as black, red, and blue are mostly reprocessed from recycled plastic products, and cannot be filled with food. Ultra-thin plastic bags (thickness below 0.025 mm) are also prohibited foods. of. The vast majority of these recycled plastic bags are produced by small enterprises or home workshops, and a considerable number of them are recycled and processed using the collected waste plastics, industrial wastes, and plastic waste discarded by medical institutions. They have not been disinfected and contain severely excessive quantities. For bacteria and carcinogens, the use of such plastic products to package cooked foods directly at the entrance will have extremely serious consequences on the health of consumers.
Generally non-toxic plastic bags are milky white, translucent, or colorless and transparent, flexible, lubricated when touched by hands, and waxes on the surface; toxic plastic bags are turbid or pale yellow in color and sticky. The proportion of non-toxic plastic bags is smaller than that of water and can be surfaced. The proportion of toxic plastic bags is greater than that of water, and they will sink into water. The non-toxic plastic bag shakes hard and sounds crisp; poisonous people feel awkward and astringent. The non-toxic polyethylene plastic bag is flammable. The flame is blue and the top is yellow. When it burns, it drips like a candle tears. It has a stone scent and burns less smoke. The toxic polyvinyl chloride plastic bag is not flammable and it is extinguished from the fire. , The flame is yellow, the bottom is green, softening can pull, and emit a pungent smell of hydrochloric acid. Health experts called on the public to purchase fresh foods in clean paper bags and bags. At the same time, frozen and frozen foods in the refrigerator should also use plastic wrap instead of ordinary plastic bags. Because of the special process and raw materials of cling film, it has good air permeability and preservation performance. However, if the ordinary plastic bag is used for a long time, the food will soon deteriorate and rot, and it can not achieve the purpose of preservation.
The US FDA has been actively encouraging the recycling of plastic packaging materials to produce new food packaging containers, but the application of recycled plastics to food packaging involves many health and safety issues. To this end, the FDA recently issued a document evaluating various applications of recycled plastics in food packaging, and emphasized the issues that need attention when applying such products. Recycling of plastic packaging materials, and the most worrying aspect of the use and packaging of food products are that various contaminants that have been used by consumers may appear in food packaging products made from recycled materials, as well as recycled materials that are not controlled. Used in food packaging. Various excipients used in recycled materials may not comply with food safety-related regulations. In order to remove these concerns, the FDA stipulates that regardless of whether or not the plastic products produced during the recycling process can be used in food packaging, it must first be reviewed accordingly. Producers who want to use recycled plastics in food packaging must provide the FDA with relevant review materials, including providing a full description of the recycling process; the source of the recycled plastic, and a description of the source's controls to ensure that the recycled plastic is used. The beginning is to comply with the provisions available. The description of the process measures ensures that the recycled plastic is not contaminated on several points. When recycled plastics are used as a raw material to make plastic substitutes, the production unit must prove that these substitutes are not contaminated with the food, or the test proves that the regeneration process used can remove possible contamination.

◆ Waste plastic parts and components: Fuji Electric used its production bases in Fuji Xerox Shenzhen Co., Ltd. to use recycled plastic molded parts jointly developed by the company and UMG ABS. This is the first time that the company has used recycled plastics in its production of products from overseas locations. Recycled plastic is ABS resin, which contains more than 25% of recycled plastic raw materials. Fuji Xerox has separated the plastic parts from the photocopiers recovered from the market and, after selection, smashes and cleans the recycled plastic materials that are finally processed into pellets. The material meets the quality standards of UMG ABS. Fuji Xerox's desktop office laser printers "DocuPrint 211" and "DocuPrint 181" have already used recycled plastic parts for a total of nine parts such as cell covers and positioners. The use of recycled plastic parts is part of the company’s project to promote the recycling of "closed-loop systems." In the future, Fujitsu will use 1,000 tons of recycled plastics in Fuji Xerox's recycled plastics, as it is introduced into China's production bases and introduced into pallets carrying goods.
