How to Shrink Plastic with Hot air?

Hot air is ideal for the processing of shrink films and shrink tubes because when plastic is heated it curls and bends. There are two main areas when it comes to heat shrinking. Heat shrinking within packaging technology and heat shrinking in electrical engineering. Leister hot air blowers and heaters are used in all areas in which hot air is conceivable in the manufacturing process: mechanical engineering, auto, food, packaging and building industries.
