Shrink Tunnel adopts a constant temperature heat shrinking system, high-power motor drive and stainless steel heating tube, which can achieve the whole shrinking process with high speed and good quality. At the same time, the shrink film is covered tightly, the sealing line is straight and centered, and the vision is smooth. The automatic work flow of the whole production line can meet the needs of the factory for large-scale packaging. In addition, Shrink Packing Machine can also be connected to the whole line of the later automation.
POF Shrink Tunnel adopts lower air transport, and the air volume is arbitrarily adjusted by the frequency converter.
Shrink Tunnel adopts solid shaft conveying, which is controlled by frequency converter, and the speed is stepless adjustable. The upper part of furnace cavity can be opened, which is convenient for cleaning and maintenance and daily maintenance. At the same time, the high-temperature silicone used in the conveyor belt can also be optionally red or white. Visual high-temperature toughened glass window of Sealing Packing Machine can easily realize real-time observation of shrinkage process. Powerful expandable function: optional front-end power feeding line and rear-end non power storage platform
