Users are confused by tens of thousands of Air Convection Shrink Tunnels in the market. Some of them can be built in small size and offered a very low and attractive price. We offer a better choice of balance between affordable price and years of operation. Often overlooked, the design of an Air Convection Shrink Tunnel often plays a large role in the quality and appearance of the packaged products. If an Air Convection Shrink Tunnel can not impart sufficient energy into the shrink film early enough to create the maximum ballooning effect and allow the bubble to collapse at just the right rate, the shrink film will not shrink to its maximum extent, imperfections will not be cleaned up and end result will be less than desirable.
