ABSTRACT:
There is disclosed an improved strippable laminated tape particularly adapted for making carton joints, and for sealing flaps of cartons and the like, which can be easily stripped to free the joints or the flaps. The tape has a Kraft paper upper layer, preferably with filaments between the layers, and a bottom layer of low internal bond, all united, and with a longitudinal cut that may be straight, zigzag, diamond, or of other form, extending through the bottom layer. The under surface of the bottom layer may have adhesive on it. The tape is applied in usual manner to carton panels or flaps. To open the carton or separate the joint, the tape is stripped by pulling up one end, in which action the bottom layer delaminates the adhesive and parts of the low internal bond bottom layer, but due to the cut through that bottom layer, the sides or flaps are free, collapsing the carton, or providing ready access.
