This plastic is generally used for packaging foods and beverages, especially carbonated soft drinks, juices and water bottles. Its raw materials are ethylene glycol and terephthalic acid. These are manufactured to form a polymer chain and then into PET resin pellets which can then be heated to a molten liquid. This allows the plastic to be extruded or molded into practically any shape.
PET can also be stretched thinly into a sheet to create PET film, which is used in video, photo and packaging applications.
It’s high strength and the option of clear and a range of colours also makes it a popular packaging material for health, beauty and cleaning products. PET is also recognised by global health authorities in safety for food, beverage, personal care, pharmaceutical and medical applications.
