The Process of Blowing Pet Bottles Automatically
The production of PET bottles automatically is really amazing. It begins with a unique kind of plastic called PET, which stands for polyethylene terephthalate. This plastic is heated to the point that it melts, and then it is placed in a bottle-shaped mold. Once the plastic is in the mold, high-pressure air gets blown into the plastic. This air causes the plastic to swell – it stretches out to fill the shape of the bottle. Finally, the bottle cools and is pulled out of the mold, prepared to store your favorite drinks or household items.
