Bubble wrap is a protective packaging material made from plastic. It consists of a sheet of plastic with air-filled bubbles that provide cushioning for fragile items during shipping and handling. The bubbles help absorb shock and prevent damage to the contents inside. Originally invented in the 1960s, bubble wrap was first intended as a textured wallpaper. However, it quickly found its primary use in packaging. Today, it is widely used by businesses and individuals alike to protect items such as electronics, glassware, and collectibles during transport, making it an essential tool in the shipping industry.
