Recycling and reuse of plastic stretch film and polyolefin shrink film in China

Recycling and reuse of plastic stretch film and polyolefin shrink film in China

China's stretch film and polyolefin shrink film industry has developed rapidly in recent years, relevant data show. The world's largest shrink film and polyolefin shrink film production is no. 2. At the same time, China's stretch film and polyolefin shrink film has a shortage of raw materials, big imports and expensive prices. According to statistics, China imports more than one million tons of plastic raw materials every year. With the soaring international oil prices, the plastics industry as a whole has been in a marginal situation.

The industrial structure adjustment of China's stretch film and polyolefin shrink film industry needs to be accelerated urgently, according to experts from the technical development base of modified stretch film and polyolefin shrink film. As one of the directions of structural adjustment, the recycling problem of the abandoned stretch film and polyolefin shrink film has become the key of the whole cycle industrial chain, and it is also a part of the high technical content and high profit of the whole industry at present. At the moment, less than 10% of China's abandoned stretch film and polyolefin shrink film and its packaging is recycled, compared with 26% in Japan. In some developed countries, the development and research on the recycling and utilization of stretch film and polyolefin shrink film started early, and many technologies have become mature day by day and produced good benefits. China's shrink film and polyolefin shrink film recycling industry is a sunrise environmental protection industry with great potential. In terms of economic benefits, the biggest advantage of waste stretch film and polyolefin shrink film recycling industry is low cost. According to the calculation, at present, the raw material price of stretch film and polyolefin shrink film is compared on the basis of the raw material price. The cost of the product processed by the waste stretch film and polyolefin shrink film is only about 50% of the original material of stretch film and polyolefin shrink film.

There are problems in the development of the recycling and utilization industry of stretch film and polyolefin shrink film

At present, there are four major problems in the development of the recycling and utilization industry of waste stretch film and polyolefin shrink film in China: expert analysis.

There is a lack of awareness about the recycling of waste stretch film and polyolefin shrink film. It is widely believed that products made with regenerated stretch film and polyolefin shrink film are inferior products. Few governments have specific policies to support the recycling and reprocessing industries of abandoned stretch film and polyolefin shrink film. I. society lacks rational understanding of this industry and government policy support is insufficient. People are not very environmentally conscious.

At present, there is still a shortage of experts and scholars with professional experience. The professional committee of regenerated stretch film and polyolefin shrink film industry association of China was established in 2004. It is difficult to make a comprehensive plan for the development of the industry.

Low technical content. In many places, there appeared some workshops about the old stretch film and polyolefin shrink film recycling and processing points. Thirdly, the entry threshold of the old stretch film and polyolefin shrink film recycling and utilization industry was low. The backward production equipment and the lack of technical personnel result in low technical content and unstable quality.
