Plastic bags can be seen everywhere in people's daily life. The advantages of being cheap, extremely light weight, large capacity, and easy to store are widely used. However, since China implemented the plastic limit order in 2008, all kinds of commodity retail stores are not allowed to provide free of charge. After the plastic shopping bag, the plastic bag was pushed to the top of the wind and became the main culprit of environmental pollution. The performance of plastic bags has been mixed and has been widely disputed by the industry.
For a long time, plastic bags have brought great convenience to human life. Moreover, plastic bags are low in cost, vary in size and style, and are widely used in large, medium and small commodity retail stores, and plastic bags have become an important means of packaging marketing. The exclusive plastic bag packaging design can better reflect the seller's brand image.
Plastic bags can not be naturally decomposed, difficult to recycle, easy to burn, and release toxic gases, poor heat resistance, easy to age, mostly for one-time use, and harmful to environmental pollution, which has caused serious white pollution sources and destroyed the balance of ecological environment. Therefore, it has been banned from use and production by some countries.
According to the National Development and Reform Commission, the “plastic limit order†was implemented for 8 years, and the use of plastic shopping bags was significantly reduced. Among them, shopping malls and supermarkets were the most obvious, with a reduction of about 75%. According to the survey of relevant associations, if the current consumption of plastic bags in supermarkets is reduced by about 2/3, the annual consumption of plastics can be reduced by more than 270,000 tons, equivalent to 1.6 million tons of oil. Moreover, the release of the “plastic limit order†and the release of relevant standards such as plastic shopping bags have restricted the production of unqualified plastic bags from the source. However, due to the small scale and large number of plastic bag production enterprises, there are still many family workshops in production. Supervision is more difficult.
As for the saying that plastic bags pollute the environment, there are two plastic leaders who have recently expressed their opposition. They believe that the energy required to make plastic bags is 40% less than that of paper bags, and the resulting solid waste is 80% less than paper bags. And a canvas bag needs to be used repeatedly for at least 171 times to completely offset the equivalent value of the energy and resources it uses in the manufacturing process, which is a real waste of resources. In addition, the plastic bag itself is in contrast to the environment, but people have developed an incorrect concept of long-term use, resulting in a large number of waste plastic bags and environmental pollution.
Experts pointed out that we need to treat the plastic bag in a dialectical way. The advantage of the plastic bag itself is that it is difficult to replace other products. However, its impact on the environment cannot be ignored. According to the report of Global Plastics Network, in recent years, Biodegradable plastic bags have also been introduced to effectively regulate the degradation time and cycle of plastics. While giving full play to the functions of bio-plastic packaging materials, the pollution and impact of plastic packaging materials on the ecological environment are reduced and eliminated. Future degradable environmentally friendly plastic bags will have great development prospects.
