The recycling value of plastic bags is relatively low. In addition to causing 'visual pollution' pollution scattered in urban streets, tourist areas, water bodies, roads and railways, plastic bags also have potential hazards. The plastic structure is stable, it is not easy to be degraded by natural microbial bacteria, and it will not be separated for a long time in the natural environment. This means that if the waste plastic waste is not recycled, it will become a permanent pollutant in the environment and accumulate continuously, which will cause great harm to the environment. First, it affects the development of agriculture. Waste plastic products mixed soil in continuous cumulative will influence crops absorption nutrient and water lead to crop production. Second, it poses a threat to the survival of animals. Waste plastic products discarded on land or in water are swallowed by animals as food, resulting in animal death. Sheep like to eat oily residues wrapped in plastic bags, but they often eat them together with plastic bags. Because the plastic they eat is difficult to digest in their stomachs for a long time, the stomachs of these sheep are packed, can no longer eat, and finally can only be starved to death. Such things are common in zoos, pastoral areas, rural areas and the sea. Third, waste plastics will not only occupy a large amount of land with landfill, but also the occupied land will not be restored for a long time, affecting the sustainable use of the land. If waste plastic products entering domestic waste are buried, they will not degrade for 200 years. Moreover, plastic bags using petroleum as raw materials not only consume a large amount of resources, but also cannot be decomposed and buried underground, which will pollute land and rivers. In addition, plastic bags themselves release harmful gases. Especially cooked food, packed in plastic bags, often deteriorate. The impact of deteriorated food on children's healthy development is particularly prominent. Plastic bags consume a lot of energy. According to estimates, China needs to consume 3 tons of oil per ton of plastic bags, while China can use at least 3 million ordinary cars for 5 years. Change this situation, eliminate the trend of ultra-thin plastic bags, and benefit the country and the people! The harm of plastic bags to human health medical experts pointed out that food, especially cooked food, is often easy to deteriorate after being packed in plastic bags. After people eat such deteriorated food, it is easy to cause food poisoning symptoms such as vomiting and diarrhea. In addition, the plastic itself will release harmful gases, and the concentration will increase with the increase of sealing time due to long-term accumulation in the sealed bag, resulting in different degrees of pollution of the food in the bag, the impact on children's healthy development is particularly prominent. Plastic bags with particularly dark colors often used on stalls have great harm. It is reprocessed from recycled waste plastic products, which is extremely harmful to human body and cannot be used to hold directly imported food; In addition, PVC plastic products cannot be used to store alcoholic food and oily food, otherwise lead in the bag will dissolve into the food; At the same time, this kind of plastic bag cannot hold food with a temperature above 50 C. Insiders pointed out that most of the plastic bags currently sold and used in the market are produced by small enterprises or family workshops around the world, and a considerable number are recycled plastic products, using waste plastics collected by garbage stations, industrial wastes and plastic wastes discarded by medical institutions for recycling and processing, they are privately processed into food bags and put on the market without disinfection. These recycled plastics contain bacteria and carcinogens that seriously exceed the standard. Using this plastic product to pack cooked food that is directly imported has extremely serious consequences for the health of consumers. Such plastic bags contain a large number of bacteria that cannot be seen by naked eyes. Long-term use of such disposable plastic food bags can easily lead to chronic food poisoning. In this regard, consumers can use the following methods to detect toxic and non-toxic plastic bags: sensory detection method: non-toxic plastic bags are milky white, translucent, or colorless and transparent, flexible, hand-feeling lubrication, the surface seems to have wax; The toxic plastic bag is turbid or yellowish and feels sticky. Water Detection Method: Place the plastic bag in water and press it into the bottom of the water. The non-toxic plastic bag has a small specific gravity and can surface. The toxic plastic bag has a large specific gravity and sinks. Jitter detection method: hold one end of the plastic bag by hand and shake it hard, and the crisp sound is non-toxic; The sound is poisonous. Fire detection method: non-toxic polyethylene plastic bags are flammable, with blue flame and yellow upper end. When burning, they drip like candle tears, with paraffin flavor and less smoke; Toxic PVC plastic bags are non-flammable, extinguish immediately from the fire, the flame is yellow, the bottom is green, softening can draw wire, and have the pungent smell of hydrochloric acid.
