Against the backdrop of growing global attention to environmental protection and sustainable resource utilization, the plastics industry is undergoing a profound transformation. While traditional plastics have brought convenience, their non-biodegradable nature and high energy consumption in production have triggered serious environmental problems. Environmentally friendly energy-saving plastics have emerged, aiming to reduce environmental pollution and energy consumption, becoming a key force in promoting the green transformation of the plastics industry. The recycling and regeneration of PET waste films in the electronics industry is a significant practice in the development of such plastics, demonstrating a trend that brings new development directions and opportunities to various industries.
