What is a PET plastic bottle?

PET is the abbreviation for polyethylene terephthalate, and polyethylene terephthalate is used to make 70% of the soft drink bottles produced worldwide. This makes it the most popular choice globally, making it far ahead of competitors in aluminum and glass.

Polyethylene terephthalate is a natural and transparent thermoplastic, which has wide applicability in the bottling and packaging industries. When used in combination with other materials, it can also be used as an engineering plastic. Because of its applicability in the textile industry, polyester has given people a better understanding of its name.

Where does polyethylene terephthalate come from?

PET was developed by DuPont chemists more than 70 years ago. They set out to find polymer materials that can be used in the textile industry and produced PET during the synthesis of ethylene glycol and terephthalic acid. They noticed that it is a very strong material without any additives, especially when they consider its lightweight.

This strength means that less material is required in certain applications, which explains why plastic bottles are made of relatively thin-looking materials. Research also shows that PET is extremely sustainable because it can be recycled and reused repeatedly.

Why is polyethylene terephthalate so useful?

Due to the combination of many factors, PET is a useful material. For the bottling industry, PET is useful because it can provide manufacturers with a certain degree of chemical resistance. It does not react with food or water, so it is very suitable for consumer packaging.

It is also almost completely shatterproof and safer to use than glass substitutes. PET is also much lighter than glass, making it easier to transport the finished product.

You must also consider the fact that polyethylene terephthalate is a widely available substance and relatively affordable. After consumers use it, they can recycle it. This can be done in one of two ways, and plastics will use one of the following two ways:

a) After a series of washing processes or

b) Break it down into a set of raw materials.
