Here we talk about transparent bottles, if PET plastic bottles and PVC plastic bottles are mixed together. According to the molding method: PET plastic bottle molding is carried out in two steps, that is, injection molding and blow molding.
So there is a filling port at the bottom of each PET plastic bottle. Take a look and you will know. PVC plastic bottles are blow-molded and do not require injection molding, so there is no injection port.
So a PET bottle is a plastic bottle, and a PVC plastic bottle is not. If it is mass-produced, steam the whole bottle with steam,
After the high-temperature steam PVC plastic bottles will become opaque, PET plastic bottles are still transparent, sorting them both easy to recognize and save, and after steaming the label adhesive tape will automatically degummed, gently removed by hand to remove.
Bottle tablets do not recognize, can only be boiled or steam steamed, boiled or steamed PVC material becomes opaque, PET material is still transparent, the opaque selected PET is pure.
