While PET is generally considered safe for food and beverage packaging, concerns have been raised about the release of harmful chemicals during its production, use, and disposal. One of the primary concerns is the leaching of antimony, a catalyst used in the manufacture of PET. Elevated levels of antimony can pose health risks, including respiratory and cardiovascular issues. Additionally, when PET is exposed to high temperatures, it may release acetaldehyde, a compound that can affect the taste and odor of beverages.
