<p>A tear tape opening system is provided for establishing an opening in a package or carton (10) formed of corrugated board wherein the corrugated board consists of an outside liner (24), an inside liner (26) and a corrugating medium (28) thereinbetween, wherein the outside liner has outside and inside surfaces and the inside liner has outside and inside surfaces, and the inside surfaces of the outside and inside liners face the corrugating medium. The tear tape opening system according to the present invention includes a tear tape (30) adhered to the outside surface of the inside liner (26) along the desired line of opening and a paperbacked hot melt coated tape (32), wider than the tear tape, adhered to the outside surface of the outside liner (24) along the desired line of opening so as to guide the tear formed by the tear tape and reinforce and stabilize the edges of the tear along the outside surface of the outside liner. By utilisation of a paperbacked hot melt coated tape for the tear guide system, the tape is capable of being applied to the outside surface of the outside liner of the corrugated board during the incorporation of the outside liner in the corrugated board. Thus, the paperbacked hot melt coated tape is applied in the doublebacker segment of the corrugated board forming machine and the paperbacking prevents the hot melt coated tape from being directly contacted by the hot plates resulting in the melting and smearing thereof.</p> |
