As a subject matter expert in materials science with a focus on polymers, I can provide you with an informed perspective on the safety of PET plastic.
PET, or polyethylene terephthalate, is a type of plastic that is commonly used in the production of bottles, containers, and packaging materials. It is considered safe for use in food and beverage packaging under normal conditions. PET is made to be strong, lightweight, and shatter-resistant, which makes it an ideal material for single-use containers.
However, there are some concerns regarding PET plastic. When PET plastic is exposed to high temperatures, it can potentially leach harmful chemicals into the contents it holds. For instance, studies have shown that certain additives and plasticizers, such as phthalates and bisphenol A (BPA), can migrate from the plastic into the food or beverage, particularly when the plastic is heated. While BPA is not used in the production of PET, other substances might be of concern.
It's also important to note that repeated use of PET plastic containers can lead to a breakdown of the plastic over time, which may increase the risk of chemical leaching. For this reason, PET bottles are generally recommended for single-use applications.
In summary, PET plastic is generally recognized as safe for its intended use, but caution should be taken with prolonged use or exposure to high temperatures.

Previous research has focused on plastics containing the chemical bisphenol-a (BPA). During that time regular PET plastic water bottles have maintained a reputation as safe, at least as far as human health is concerned. But new evidence suggests that PET, or polyethylene terephthalate, may not be so benign after all.
