Abstract
The packaging method glues or otherwise secures a sheet of shrink wrap film to the bottom of a shipping package or carton. The sheet extends upward on both sides so as to be temporarily attached to the flaps of the shipping carton, typically by dots of glue. After the contents are placed in the shipping carton, the film is folded over the contents. Then a label, typically with a bar code, holds the film in place. The package is scanned to assure that the label is in place, and the package is exposed to a heat tunnel to shrink the shrink wrap film. The flaps of the carton are then sealed in a conventional way.
