ABSTRACT:
A packaging device includes a film fitting mechanism, a film shrinking mechanism and a controller. The film fitting mechanism fits a tubular heat shrinkage film over a film cylinder and moves the film a distance along the cylinder and cuts a length of the film off. The length of the film is then conveyed to the film shrinking mechanism. The film shrinking mechanism is arranged next to the film fitting mechanism and includes a base for supporting an article to be packed with the film that is cut by the film fitting mechanism and heating units for supplying high temperature air flows to the film thereby making the film shrink and tightly wrap over the article. The controller controls and coordinates the operations between the film fitting mechanism and the film shrinking mechanism.
