If PET bottles and PVC bottles are mixed, the transparent bottles are all mentioned here. PET bottle molding is carried out in two steps, that is, injection molding and then blow molding, so each PET bottle has a filling port at the bottom. Take a look and you will know. PVC is blow-molded and does not require injection molding, so there is no injection port. So a PET bottle is filled with a material injection port, no PVC. If it is mass-produced, steam the whole bottle with steam, the PVC after high-temperature steam will become opaque, PET will be transparent, sorting will be easy to recognize and save, and after the steamed label tape will be Automatic degumming, removed with a light tear. Bottle tablets do not recognize, can only be boiled or steamed, boiled or steamed PVC becomes opaque, PET is still transparent, the opaque PET is pure.
