The roll is made out of three layers of different plastics that 3M developed, including a gray, internal adhesive layer that sticks to itself.There’s also a middle cushioning layer that seems similar to bubble wrap to protect items during shipping, and a tougher outside layer that is tear- and water-resistant. It comes in rolls of assorted sizes, almost like wrapping paper: 10-foot, 20-foot, and 40-foot rolls are available now with prices ranging from $12.99 to $48.99, and a 200-foot bulk role will soon be available in August 2019.
