With the vigorous development of the electronics industry, polyethylene terephthalate (PET) films play an indispensable role in the manufacturing of numerous electronic products due to their excellent insulation, high transparency, good mechanical properties, and chemical stability. These applications include multi-layer ceramic capacitors (MLCC), flexible circuit boards, liquid crystal displays, and more. However, with the rapid expansion of the electronics industry, the generation of waste PET films has been increasing day by day. If these waste films are not properly disposed of, they will not only cause enormous waste of resources but also impose a heavy burden on the environment. Therefore, achieving efficient regeneration and preparation of waste PET films in the electronics industry is of far-reaching and significant importance for promoting the sustainable development of the electronics industry, alleviating resource pressure, and reducing environmental pollution.
