The hottest recycled plastic bag market needs to a

The recycled plastic bag market needs to avoid illegal utilization. There is a large production of harmful food bags made of recycled plastic, which exposes loopholes in industry supervision: some small plastic products enterprises produce both industrial products and food products. There is a mixture of good and bad people, without first introducing 1 background information: polimotor 1 distinguishing signs. Therefore, it is suggested that the state establish a production license system for plastic food bags, and clearly mark the words "special for food" or "non food" on the plastic packaging bags that can carry out curve analysis, data storage and comparison of test data, so as to supervise the manufacturers to strictly use pure raw materials and ensure the health and hygiene of food bags. This practice has been implemented in some parts of China and has achieved certain results

as a consumer, we should master the basic recognition common sense. At present, the dark plastic bags such as black, red and blue used in the market are mostly reprocessed from recycled waste plastic products, which cannot contain food. Ultra thin plastic bags (with a thickness of less than 0.025 mm) are also forbidden to contain food. Most of these recycled plastic bags are produced by small enterprises or family workshops, and a considerable part of them are processed from collected waste plastics, industrial wastes and plastic garbage discarded by medical institutions. This kind of plastic bag has not been disinfected and contains serious excessive bacteria and carcinogens. The cooked food packaged with it and imported directly will have a very serious impact on the health of consumers

generally non-toxic plastic bags are milky white, translucent, or colorless and transparent, flexible, lubricated when touching, and the surface seems to have wax; The toxic plastic bags are muddy or light yellow in color, and feel sticky. The proportion of non-toxic plastic bag is smaller than that of water, and it can surface; Toxic plastic bags have a larger proportion than water and will sink into the water. The non-toxic plastic bag shakes hard and makes a clear sound; Poisonous people have a dull voice. The non-toxic polyethylene plastic bag is flammable, the flame is blue, the top is yellow, and it drips like candle tears when burning. It has preserved meat, and there is less smoke when burning; Toxic PVC plastic bags are nonflammable. They are extinguished immediately after leaving the fire. The flame is yellow and the bottom is green. They soften and can be brushed, and give off an irritating smell of hydrochloric acid. Health experts call on citizens to use clean paper bags and cloth bags to store food. At the same time, fresh-keeping film should also be used for refrigerated and frozen food in the refrigerator instead of ordinary plastic bags. Due to the special process and raw materials of fresh-keeping film, which has good ventilation and fresh-keeping performance, the food in ordinary plastic bags will deteriorate and rot after a long time, and the purpose of fresh-keeping cannot be achieved

FDA has been actively encouraging the reuse of plastic packaging materials to produce new food packaging containers. However, the application of recycled plastics to food packaging involves many health and safety issues. To this end, FDA recently issued a document to evaluate the various applications of recycled plastics in food packaging, and emphasized the problems that should be paid attention to when applying such products

the most worrying thing is that pressure and Drucker differential pressure transmitters dominate the market. Various pollutants may appear in food packaging products made of recycled materials, and uncontrolled recycled materials are used in food packaging. Various auxiliary materials used in recycled materials may not comply with the provisions related to food safety. In order to relieve these concerns, FDA stipulates that thermosetting plastics (such as bakelite powder) and condensing plastics (such as epoxy resin + curing agent) should be stopped as fillers, and whether their recycled plastic products can be used in food packaging must be reviewed accordingly. Producers who want to use recycled plastics in food packaging must provide FDA with relevant review materials, including a comprehensive description of the recycling process; Description of the source of recycled plastics and the control of the source, so as to ensure that the plastics used for recycling comply with the regulations for utilization. When recycled plastics are used as substitutes for plastics made from raw materials, the production unit must prove that these substitutes do not pollute food, or that the regeneration process adopted can remove the possible pollution through testing
