ABSTRACT:
A shrink tunnel assembly for wrapping an article with polymeric shrink film includes a shrink tunnel having a heating zone, and conveyor means for carrying an article to the heating zone and away from it. While in the heating zone, polymeric shrink film covering an article avoids contacting any solid surface, thereby protecting the article from marring and destruction.
