In recent years, with the continued rapid development of the plastics industry, plastic packaging has found widespread application. However, as the volume of plastic packaging waste continues to rise, the issue of "white pollution" has begun to seriously impact the ecological environment. Therefore, it has become an urgent priority to use materials with better performance-to-price ratios when selecting and ecologically designing plastic packaging materials, to develop biodegradable plastics using technologies and methods that are more in line with contemporary trends, and to step up efforts to recycle and reuse plastic waste. China is a major global producer and consumer of plastics, as well as one of the largest importers of plastics and plastic waste. Currently, global plastic consumption has exceeded 260 million tons. In 2008, China's apparent plastic consumption reached 51.914 million tons, accounting for roughly 20% of the world's total plastic consumption. China boasts a huge market for plastic products. According to available data, China's output of plastic packaging materials in 2008 was 12.61 million tons, representing about one-third of the country's total plastic product output. Adding to this the plastics used in agricultural applications and single-use daily consumer goods, roughly half of all plastic products end up as waste within a single year—yet the current recycling rate remains relatively low. Moreover, China faces a significant annual shortfall in plastics, with about 45% of its needs being met through imports. Thus, there is great potential for strengthening the resource recovery and reuse of plastic waste. Although China has established and explored various approaches to the resource recovery and reuse of plastic waste, some regions still rely on crude landfill practices, causing substantial environmental pollution. Furthermore, as the ranks of online shoppers continue to grow, the problem of courier-related pollution is becoming increasingly prominent: courier packaging materials can take up to 100 years to decompose if buried in soil. Consequently, research into technologies for the recycling and reuse of plastic packaging is becoming ever more pressing. Recently, an American company announced a groundbreaking new technology for recycling composite films, breaking the spell of non-renewability. Parker Company reported that it has developed a “unique and innovative” technology capable of recycling multilayer flexible composite packaging films—including PET/polypropylene, PET/polyethylene, and metal-plastic composites—into recycled pellets suitable for a wide range of applications.
