Lactide

Lactide is a chemical compound formed when lactic acid molecules join together during a process called polymerization. It is a key building block for creating biodegradable plastics known as polylactic acid (PLA). These plastics are eco-friendly because they can break down naturally in the environment over time. Lactide exists mainly in two forms—d-isomer and l-isomer—that influence the properties of the resulting PLA, such as strength and clarity. In summary, lactide is an essential intermediate used to produce sustainable plastics often used in packaging, medical devices, and 3D printing.
