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.

Die-cast Aluminum Cookware is a slower and more expensive process, however the end result is that the body thickness is generally thicker than pressed aluminum, and the bottom and the rims can be made even thicker than the sidewalls. This helps to prevent warping, or going "out of round". Cast Aluminum Cookware is also more porous than pressed aluminum, which results in better heat retention. Different shape, thickness, design patterns can be realized by mould.
