Shrink wrap apparatus and method of shrink wrapping products

摘要

A tunnel for shrink wrapping at least one product includes a housing having an interior space with a top, a bottom, an entrance and an exit. A conveyor belt passes through the interior space from the entrance to the exit. The conveyor belt is substantially unobstructed on upper and lower sides and includes an opened configuration allowing substantial air flow therethrough at relatively low velocity. Heaters and air movers are located above and below the conveyor belt to uniformly heat products contained in shrink film and moving along the conveyor belt. The shrink tunnel further includes an adjustable riser member to allow a transverse section of the conveyor belt to be selectively adjusted in height from outside the housing.
