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 naturally makes it an eco-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 absorption by the body. The textile industry also employs it in the production of fibers for clothing and upholstery, offering a sustainable option compared to synthetic materials. Additionally, it is used in 3D printing as a filament, providing a biodegradable and versatile material for creating prototypes and end-use parts. Its applications extend to agriculture, where it is used for mulch films that decompose after use, reducing environmental impact.
