ABSTRACT:
A package consisting in an article packaged by a packaging film exhibiting heat shrinkability is disclosed. The packaging film has its wrapping terminal end formed with a protuberant tearing tab, and a severing tape is bonded to the inner surface of the film for extending from the distal end of the tearing tab along the entire length of the film along the article wrapping direction. The severing tape has a width lesser than the width of the tearing tab and is formed of a material having heat shrinkage percentage lower than that of the film. The tearing tab has its distal end reduced in width for reducing the allowance for heat fusion. For reducing the allowance for heat fusion, the distal end of the tearing tab is semi-circular in contour. The distal end of the severing tape substantially in register with the center sealing region of the film is designed as a non-fusing region to facilitate the exfoliation of the severing tape.
