With the development of economy, people pay more and more attention to packaging. Now packaging of products has become an indispensable part of commodities. Plastics have the advantages of good physical and chemical properties, good mechanical properties, free modeling, good printability and so on. At present, the global annual plastic output is more than 100 million tons, and packaging accounts for more than 30% of the whole market.
The key to the rapid development of plastic packaging is that its performance price ratio is higher than that of today's materials, but after the commodity is used, the packaging is discarded. From the perspective of recycling, this kind of material is not easy to recycle and decompose. A large number of discarded plastics will cause serious pollution of social environment, which will also cause many serious social problems. Plastic packaging waste has accounted for more than 85% of the waste plastics. Therefore, recycling and recycling technology has been more and more concerned by the society.
