Where did polyethylene terephthalate come from? Why is polyethylene terephthalate such a useful material? This can be done in one of two ways, the plastic will either: a go through a series of washing processes or b it will be broken down into a set of raw materials.
How are PET plastic bottles made? There is an array of different methods that are used to make PET plastic bottles, but the most common method can be broken down into the following steps: Step 1 : The PET is initially heated up, melting it down into a molten state, before being placed into a tube shaped mould.
Step 5 : The bottles are now ready to be transported to their destination. What is the role of the compressor when creating PET plastic bottles? Do quality tests take place?

As the liquid becomes thicker, the polymer chains grow. The reaction is stopped when the desired polymer chain length is achieved. This produces thin strands of PET which are extruded and cooled. The strands are cut into pellets which can be remelted and stretched later to produce the desired material. The video below outlines the process of getting from these pellets to plastic bottles Skip to 28 seconds in. It has a density of 1. PET Plastic is a strong, clear, plastic commonly used for food packaging, plastic bottles, and household containers.
Its chemical name is polyethylene terephthalate. It is identified by the number 1 encircled by the recycle symbol.
The short term future of PET is bright. It is a cheap, lightweight material with a huge variety of uses. It keeps food and drink safe all over the world, makes some great clothing, and even is helping the fight against malaria. The long term future depends largely on how the issue of plastic pollution is solved. It is used not only for beverage containers, but also the plastic packaging for nuts, rice, pasta, beans, salad dressing, squeeze bottles of ketchup, mustard, mayo, relish, mouthwash, shampoo, conditioner, hand soap Almost all of the plastics wrapped around your food, beverages, and personal care items.
Making PET plastic begins with drilling or fracking for crude oil. That oil is brought by tanker trucks to a refinery where they use fractional distillation to separate the crude oil into easier to use components.
Those components include Ethylene glycol , a molecule that is used for making polyester fibers and antifreeze formulas, and terephthalic acid. Terephthalic acid is a carboxylic powdery acid with a chemical structure containing a benzene ring. Interesting fact: molecules that contain benzene rings have been associated with cancer.
These monomers a molecule that can be bonded to other identical molecules attach to each other via polymerization to make a chain, and BINGO! We have the basics of PET plastic, a light-weight, durable, water and bacteria resistant product that solves all of our woes.
With a better understanding of why so much plastic is used to package our beverages, food, and more lightweight, cheap, durable, non reactive , we can talk about when the life of the plastic bottle ends. You do the right thing. Right now, we have seen what happens when plastic deteriorates into microplastics.
