PDC International Corporation, a manufacturer of steam, convection and infrared shrink tunnels, has introduced a heavy-duty, highly flexible steam tunnel for the precise shrinking of shrink sleeve labels at slow to moderate speeds. Speeds are adjustable within a broad range.  The new KST 55-710 has adjustments for steam volume, flow and nozzle position in a new compact design, which allows precise application of steam to specific points on the package, for best-possible aesthetics and minimal risk of bottle distortion at a very attractive price point. Containers can be filled or empty, and virtually any shape.
