There are both industrial- and consumer-related uses for PET plastics. The following are some examples of the most common uses for polyethylene therephthalate:
It is commonly used in bottles and other plastic containers. This includes soda bottles, bakery products, water bottles, peanut butter jars and even in frozen foods packaging.
It is used to hold cosmetics. Since it is easy to mold, manufacturers can create very specific shapes for a variety of cosmetic products.
It is commonly used for the storage of chemicals, including household cleaners.
Why do manufacturers turn to PET plastics when they could choose other types of materials that may be more readily available? PET plastics are durable and strong. Most applications can be used repeatedly (recycling is a possibility with these products). In addition, it is transparent, making it quite versatile for various applications. It is resealable; because it is easy to mold into any shape, it is easy to seal.
It is also unlikely to shatter. Moreover, perhaps most importantly in many applications, it is an inexpensive type of plastic to use.
