Baote bottle is a kind of common plastic bottle. It is also a container that people will touch every day, such as various beverage bottles, soy sauce bottles and so on.

The raw material of plastic bottle is pet (polyethylene terephthalate), so it is also called PET plastic bottle.

Pet was initially used as man-made fiber, film, tape, etc. the plastic bottle made of pet has the following characteristics: light weight, impact resistance.

But the bottle can't decompose naturally, so it must be recycled after using it.

From the point of view of production process, the body and cap of PET plastic bottle are completely separated. The material of bottle body and cap is different, mainly because of the elastic coefficient.

Due to the small elastic coefficient and easy deformation of pet, it is very unsafe to seal as a liquid. Therefore, HDPE is usually selected to make bottle cap and gasket for easy transportation and sales.

Because of this, in Japan, Taiwan and other regions, the bottle cap, bottle body and label will be separated before recycling. In Europe, however, there is no need to separate the cap, body and label.

They explained: "our factory has advanced automatic equipment. After entering the machine, all bottles will be cut into pieces of about 1-2cm. After the fragments are washed, the bottle body materials of different densities will be automatically layered. Then through the photoelectric screening device, they will be divided into different types of recycled fragments. "So when Europeans recycle beverage bottles, they don't have to screw the caps and tear the labels.
