Identification method of PET

1. Smell the smell first. The smell of PET is different from that of ordinary plastic. Burn it with a lighter, and then you will smell a very fragrant and comfortable smell (just burn a bottle to smell it). If PET contains other ingredients, the smell is very pungent. There is a kind of bottle that contains SEBS ingredients and cannot be used.
