Stretch film equipment in the current production, the more common next step is to introduce the stretch film equipment production technology requirements: stretch film is a stretch in the production process are directed, and in the course of heat-shrinkable thermoplastic film by. Container heat-shrinkable film early in 1936 to get the application, initially mainly used rubber film to shrink packaging of perishable foods, shrink wrap is also used to produce shrink labels and shrink caps, so not easy to print or complex shape can labeled. Commonly used in the production of extrusion blow molding or extrusion casting process to produce a thick film, and then at a temperature above the softening, longitudinal and transverse stretching at a melt temperature below the temperature of a high-elastic state, or only in one direction in which the stretch orientation, while the other direction does not stretch, the former called the biaxial stretch shrink film, shrink film which is called a one-way. Stretch film equipment in military machinery, hardware and tools applied shrink film VCI technology combined with anti-rust oil alternative methods to enhance rust resistance and so on.
