Stretch Film: Protection when it counts
Stretch film is the most versatile and the most common material for load unitization. It provides a layer of protection from dirt, is the first line of defense against theft and keeps the load together during shipment.
Stretch film is adaptable and can be used on mixed SKU loads that may not be perfect, neat and square.
Stretch film from Millwood is available as cast or blown.
Cast stretch film indicates fabrication of a film by continuously pumping the polymer through a straight dye, then chilling this hot sheet of plastic immediately after the dye by contact with a cooled "chill roll." Film thickness is determined by how fast the casting roll pulls the plastic away from the dye.
Blown stretch film indicates the fabrication of a film by continuously pumping the polymer through a circular dye, then filling the tube thus created with air. The volume of air contained within the tube stretches the tube or the bubble out to the desired width. In conjunction with the rate at which it is being pulled away from the dye, the desired thickness is created.
