ABSTRACT:
A multiple layered laminated tape has an upper strength layer made of a film of pre-stretched polypropylene or the like which is laminated to a very weak lower carrier layer of relatively thin low internal bond Kraft paper. The carrier layer has a coating of a water soluble adhesive which is used to apply the tape to separable portions of a cardboard carton or the like. The carrier layer serves only as a medium to "carry" the water soluble adhesive and also to provide sufficient longitudinal rigidity to permit dispensing of the tape from a standard Kraft paper type tape dispensing machine. Stripping the tape from a carton pulls away the upper plastic layer and may split the Kraft carrier layer that has low internal bond, leaving only so thin a layer of Kraft on the carton that it can very easily be broken to permit opening of the carton.
