What is the common soda bottle made of?

The common soda bottle is made of Polyethylene Terephthalate (PET).

PET is a strong and lightweight plastic that is commonly used for packaging food and beverages. It is made from a chemical called terephthalic acid, which is reacted with ethylene glycol to form a polymer. PET is a thermoplastic, which means that it can be melted and reformed, making it easy to recycle.

PET bottles are transparent and have a high resistance to breakage. They are also lightweight and easy to transport. PET bottles are used for a variety of beverages, including carbonated soft drinks, water, juice, and sports drinks.
