PET & PACKAGING

PET (Polyethylene Terephthalate) is a plastic resin and the most widely used type of polyester. It is a polymer which is composed of the combination of modified ethylene glycol and pure terephthalic acid. Depending on its thickness, PET may be semi-rigid (semi-solid) and rigid (solid). Polyethylene Terephthalate is non-reactive. It is quite resistant to reacting to other substances.  

Most important features of PET Packaging are that it is a plastic which does not contain Bisphenol-A (BPA) and it is completely recyclable. A good number of tests-analyses worldwide as well as scientific consensus shows that PET is a safe food packaging, in that it does not contain cadmium, lead and toxic materials.

PET was synthesized as the new textile fibre in the mid-1940s by DuPont chemists. By 1973, PET bottle has been recognized swiftly under patent.

PET (Polyethylene Terephthalate) was first used in food packaging in the USA during the 1970s, in an effort to minimize injury risks caused by the breaking of glass bottles. Introduced to the American and Japanese consumers in the early 70s, PET (Polyethylene Terephthalate) bottles were first produced in Turkey in the year 1979. 

Due to its being lightweight, unbreakable, healthy and more affordable than its alternatives and enabling single-use, PET has at short notice become a packaging material asked for by producers who sought the suitable food container in the storage of carbonated and non-carbonated drinks, drinking water, alcoholic beverages, cleaning products, cosmetic-personal care products of various sizes and other food. 

Produced at higher weight at the beginning, PET packaging is today more lightweight, in accordance with the principle of producing less waste. Produced as 22 grams in 1984, the 0.5 l water bottle has been reduced to 10.5 grams in the course of years. In other words, producers who introduce water with the same volume into the market are today using 53% less raw materials.

45 thousand PET water bottles would be produced out of 1 ton of PET raw material 20-25 years ago, whereas, about 95 thousand pet water bottles are produced today out of the same amount of raw material. (*)
