ABSTRACT:
A novel package wrapper is made of plastic film with a line of package-opening perforations through the film positioned in one face of the package and being overlaid by a piece of plastic tape which seals the perforations, the tape having a dry edge. The shrink wrap film and tear down tape exhibit the same shrink characteristics as those of the shrink wrap film, so that when the wrap film is shrunk during packaging the tape shrinks the same amount as the film and does not itself pucker or wrinkle the film. Package opening is accomplished by grasping the tape dry edge and pulling it toward the line of perforations. The tape peels from the wrapper film until it reaches the perforations, where continued pulling of the tape ruptures the film through the perforations and permits the film to be further torn to open the package.
