Lactide is widely used in the production of polylactic acid (PLA), a biodegradable and bioactive thermoplastic. PLA is commonly utilized in packaging materials, such as food containers, disposable tableware, and biodegradable plastic bags, due to its eco-friendly properties. In the medical field, lactide-based polymers are employed in sutures, drug delivery systems, and tissue engineering scaffolds because of their biocompatibility and controlled degradation rates. Additionally, lactide is used in the synthesis of resins and coatings, providing sustainable alternatives to petroleum-based products. Its application in 3D printing filaments is also gaining traction, offering environmentally friendly options for additive manufacturing.
