Cellophane is a thin, transparent film made from regenerated cellulose. It was invented in the early 1900s and is known for its ability to be biodegradable, making it an environmentally friendly packaging option. Cellophane is often used to wrap food items, as it provides a barrier against moisture and air, helping to preserve freshness. This material is produced by dissolving cellulose, which is derived from plant fibers, in a chemical solution. Afterward, it is extruded into sheets and dried. Cellophane is commonly used in various applications, including packaging for candies, flowers, and other products, due to its versatility and clarity.
