Glycolide is used to make which packaging film?

Explanation:
Glycolide-based polymers form biodegradable films, known as polyglycolide (PGA) and its blends, which are suitable for packaging because they can provide good barrier properties and can be composted. This makes them a practical choice for food packaging films, where clear, printable, and sealable films are desirable and environmental impact is a consideration. Bottles are typically made from PET or other durable plastics, wetsuits from elastomers, and while biodegradable polymers can be used in medical packaging, the common, well-known film application highlighted in many texts is food packaging. So, the best fit is food film.
