Shrink tunnels using a heated air system, it used for shrinkable films (PE POF PVC) that have been applied by L-bar sealers, sleeve wrappers, and sealing cutters. Designed for high production, the air flow technology is used to circulate the air to avoid bubbles and bumps in plastic film. Independent control systems regulate temperature, air velocity and conveyor speeds, our shrink tunnels feature carefully controlled air velocity and temperature that are maintained throughout the tunnel for optimum film shrink. The efficient heating system on each machine reduces the amount of electricity needed to run the machine, consequently reducing operating costs. It is used to shrink pack goods, such as cans, glass bottles, beer, mineral water etc, in wood, rolled steel, ceramics, household appliances, computers industries and more. A shrink tunnel is a heated tunnel with a conveyor system running through the tunnel. The heat settings and conveyor speed of the shrink tunnel can be adjusted to properly heat a shrink film. The heat applied to the shrink film enables the film to tightly conform to the product within the film. Shrink tunnels are used in a variety of industries for retail packaging, food packaging, and industrial packaging.
