Stretch wrap rolls have a continuous length of plastic that is wrapped around the sides of a pallet or bundle to protect the package from dust and moisture, prevent and indicate tampering, and keep items together. General purpose stretch wrap is used in most everyday applications and can be applied using wrapping machines or by hand. High-performance wrap provides high strength and puncture resistance and is thinner than other wraps. Product-concealing wrap is difficult to see through to maintain privacy and hide product labels of expensive or valuable items. Color coding and printed message wrap indicate at a glance how a product should be handled, shipped, or stored. Antistatic wrap protects electronics from static discharge. Breathable stretch wrap, also called pallet netting, is used to secure items to pallets and has holes or vents so air can circulate around the product.
