Polyethylene Terephthalate (PET)
Polyethylene Terephthalate (PET) is the most widely used thermoplastic polymer in the world.
Today’s most commonly used bottles are made of polyethylene terephthalate, which is specifically marketed as PET.
PET is a polymer made from petroleum hydrocarbons, which creates a reaction between terephthalic acid and ethylene glycol.
Polyethylene terephthalate is addressed to the textile industry as a polyester. In the food and beverage packaging industry, it is referred to as PET or PET resin. In the past, another kind of PET-P was used in the garment industry, which is using it now almost stopped.
Benefits of polyethylene terephthalate
Very abundant and as a result of relatively low prices.
Strength to super weight.
Ideal barrier against moisture.
High chemical resistance against microorganisms, which can be considered as an advantage depending on our look.
Fully resistant to crushing.
Completely recyclable and also a simple recycling process.
Highly transparent material that is ideal for applications such as packaging.
Disadvantages of polyethylene terephthalate
It has a sensitivity to oxidation. This means that there is a possibility of changing the greediness of the beverage in the bottle.
Pet is virtually indistinguishable in nature and therefore a threat to the environment.
Polyethylene Terephthalate (PET) properties:
PET properties such as transparency, lightness, high strength, low absorption of flavor, high chemical resistance, beautiful appearance, and easier and cheaper access make PET a suitable choice for making packaging bottles.
