<p>Skin packs or blister packs where an item is enclosed between a concave film and a supporting panel incorporate a filament or tape which can be peeled off to divide one face of the cavity for easy access to the convents. The break may be generated through either the film face or the supporting panel. The filament/tape may be on an inner face of the pack, with a tensile and sheat strength greater than that of the cover, or on the outside, if the adhesive bond is also stronger than the tear strength of the substrate. Does not necessarily obliterate any instructions etc. on the pack panels.</p> |
