The polyester family is used in the synthesis of fibers. Polythene terephthalate is a polyester material that with the 32 million tonnes of use currently,  has the 18% of the total global consumption of basic polymers. The high strength of this polymer has resulted in a pressure of more than 100 psi and also a good resistance to carbon dioxide passage. Polyethylene terephthalate, for the production of bottles of beverages, bottles of water, bottles of edible oils, packaging sheets.

This type of polymer is used to store various types of beverages, including carbonated drinks. Without a doubt, we all have for one time seen carbonated drinks and carbonated drinks in a plastic container, these plastics, which have created a huge transformation in the storage of feedstock (liquids). A variety of polymers is called polyethylene terephthalate or (PET). The polymer is a polyester material that consumes 32 million tons of copper, currently accounting for 18 percent of the total global consumption of basic polymers. The polyester family is also used in fiber synthesis. The current consumption of the polymer fiber grade is 9.3 million tons per year, equivalent to 5 percent of the world's total consumption of polymers. The consumption of bottle-grade in 2013 is projected to reach about 19 million tons.  

This polymer has been used for textile fiber for many years. The high strength of this polymer has the potential to withstand a pressure of more than 100 psi and also a good resistance to carbon dioxide passage, which is why PET is used to store carbonated carbon drinks. PET is very good in the packaging industry. Particularly in the packaging of food materials that can be boiled. Other uses of this polymer are PET film, which is widely used in photographic films and magnetic tape recorders. Polyethylene terephthalate is produced in two grades of fiber and bottle.
