PET stands for Polyethylene Terephthalate, a very versatile and sophisticated plastic. For sensible economic and safety reasons, plastic is used to make the most common containers on the soft drink market today, namely plastic bottles.
Used for the packaging of carbonated soft drinks, bottled water, milk, juices, sports and energy drinks, jars, punnets, tubs and trays for food, bottles for household use, personal care and pharmaceutical products, and sheets and films for packaging, PET is a type of plastic labeled with code # 1 above or near the bottom of bottles and containers.
PET is sometimes called polyester and is made from mono-ethylene glycol (MEG) and purified terephthalic acid (PTA), which are derived from crude oil and natural gas. These two crude oil derivatives are reacted under a controlled set of conditions to form a polymer. Then, in a honey-like form, this polymer is extruded through a mold plate
PET is globally recognized as a safe and recyclable packaging material for food and non-food products. PET packaging is chosen for a wide variety of applications because it is safe, strong, shatter resistant and 100% chemically recyclable into the same PET product (fiber and bottle). Manufacturers use PET to package products because of its strength, thermo stability and transparency. This material is also lightweight and can reduce costs and carbon emissions associated with transportation. Retailers use PET because it promotes high product visibility: its light weight makes it easy to stack shelves, and its shatterproof qualities ensure safety, product integrity and reduced damage. Consumers choose PET because it is portable, lightweight, resealable for efficient on-the-go hydration, 100% safe, and 100% recyclable. From an environmental perspective, two points are the most important: * PET is the most recycled packaging polymer on the shelf * PET packaging weight has been reduced by more than 30% for the last 10 years. We are often asked why we promote recyclable rather than biodegradable plastic packages. The answer is simple: because in our view, it makes more sense from an environmental and economic point of view to capture the raw materials and energy contained in plastic bottles and reuse them, instead of losing them as they degrade.
There has been a lot of confusion about PET safety after concerns emerged about the safety of various types of plastics, namely the bisphenol A (BPA)-containing polycarbonate products most often used to make rigid containers and reusable electronic devices. There is no link between PET plastic and BPA.
BPA is not used in the production of PET materials, nor is it used as a chemical building block for materials used in the manufacture of PET.
Phthalates (pronounced Tha-lates) is a class of chemicals that includes three subsets, each with different properties. Polyethylene terephthalate (PET) belongs to one of these phthalate subsets, but is not the one most commonly associated with the term. Orthophthalate is the most frequently referenced and discussed part of the phthalate in popular literature and on Internet sites and which has been the subject of negative press. Often used to make plastics more flexible, this type of phthalate is also known as a plasticizer. PET does not contain plasticizers or orthophthalates. Plasticizers have never replaced the terephthalate used in PET plants, and the two have never been mixed.
Current research shows that PET does not contain or dissolve chemicals such as estrogen such as BPA or other endocrine disruptors.
