There are myths surrounding the use of PET, a plastic material used to package many products. These myths have spread through social media, but there is nothing to fear. PET has been approved for use in food and beverage packaging by the Food and Drug Administration and similar regulating bodies around the world. It has also been proven safe for the environment. It is a useful livestock material, and its low melting point makes it a good choice for many different purposes.
PET is a highly versatile material. It is a popular material for take-home food containers, and is generally recyclable. The most common applications for PET are in the packaging industry, where it can be molded to form a variety of shapes, including microwave-safe food trays. It is durable and possesses excellent barrier properties, but it can also be subject to various types of degradation. The most common is hydrolytic degradation, which causes discoloration. Other forms of PET degradation include chain scissions, which reduce molecular weight and result in reduced performance.
Another advantage of PET is that it can be blended with other thermoplastic materials. In addition to its use in making drink bottles, it can be blended with other thermoplastics, opening up new markets and applications without much investment. This means that it can be combined with other types of materials in a wide range of products. A good example of this is polyethylene terephthalate (PET) and polyvinyl chloride (PET).
