Polylactic acid is widely used in the packaging industry, particularly for biodegradable and compostable products such as food containers, cups, and films. Its ability to break down under composting conditions makes it an environmentally friendly alternative to traditional plastics. In the medical field, it is utilized for sutures, implants, and drug delivery systems due to its biocompatibility and gradual degradation in the body. The textile industry also employs it in the production of eco-friendly fibers for clothing and fabrics. Additionally, it is used in 3D printing as a filament material, offering a sustainable option for creating prototypes and finished products. Its versatility and biodegradability make it a valuable material in various industries aiming to reduce environmental impact.
