Shrink wrap is a versatile polymer film used for packaging that protects items during transit, prevents tampering, and is available in various forms including rolls, bags, and bands. There are four main types of shrink films—polyethylene, polypropylene, polyolefin, and PVC—each suitable for different applications based on their durability and sealing properties. Pyramid Packaging, established in 1968, offers flexible packaging solutions and expertise in selecting the right shrink wrap film.
