If the PET bottle and PVC bottles together, here is transparent bottle classes.
PET bottle shape is divided into two steps, is the first injection molding and blow molding, so each of PET bottle bottom has a mouth, take a look at to know.
PVC is made of blow molding, injection is required to make, so there is no mouth.
So pick up a bottle mouth is PET, not PVC.
If mass production, the total bottle steam steaming, after high temperature steam of PVC will become opaque, PET or transparent, sorting up both recognisable and save trouble, and after steamed label tape will automatically come unglued, with handle gently tear is removed.
Bottle is bad to recognize, can only use the boiled or steamed
