ABSTRACT:
A shrink tunnel apparatus and method for the processing of packages wrapped in heat shrinkable film directs heated air streams sequentially to the package, first from below, then from both sides simultaneously and finally from above. Simultaneous with the directed heated air streams, the balance of the film is exposed to warm air effecting a differential shrink. The packages are transported through the shrink tunnel by a conveyor utilizing spaced apart rotating rollers.
