Glycolide is widely used in the production of biodegradable polymers, particularly polyglycolic acid (PGA). PGA is utilized in medical applications, such as surgical sutures, due to its high strength and ability to degrade naturally in the body. It is also employed in drug delivery systems, where it acts as a carrier for controlled release of medications. In the packaging industry, glycolide-based materials are used to create environmentally friendly products that decompose over time, reducing plastic waste. Additionally, it finds applications in the textile industry for producing fibers with unique properties like high durability and biodegradability.
