The invention discloses a method for producing plastic woven bags and packaging bags by waste polyester bottles, which relates to the technical field of plastic processing, wherein the invention adopts isopropyl triethoxysilane isocyanate to chemically modify regenerated PET, and the prepared modified PET has PET, carbamate and siloxane structures, thereby improving the processing performance of the regenerated PET and the application performance of plastic products processed by the regenerated PET; in addition, on the basis of the prepared modified PET, a proper amount of reinforcing agent, antistatic agent and antioxidant are added, so that the processing performance of the regenerated PET and the application performance of the plastic products prepared by reprocessing are further optimized in a physical blending mode. |
