Polylactic Acid (PLA) is a biodegradable thermoplastic polymer derived from renewable resources such as corn starch, sugarcane, or cassava roots. As one of the most widely used bioplastics, PLA offers a sustainable alternative to petroleum-based plastics, combining environmental benefits with versatile processing properties. It is used in a wide range of applications, from packaging materials and disposable products to 3D printing filaments, textiles, and medical devices.
