ABSTRACT:
An adhesive tape is provided which comprises a film of high density polyethylene having a density of not less than 0.94 g/cc elongated at least six times only transversely to the longitudinal direction of the tape and a layer of pressure sensitive adhesive applied at least on one side of said elongated film of high density polyethylene. The adhesive tape has a high tensile strength against a force applied in a direction transverse to the longitudinal direction of the tape. Nevertheless, the tape can be easily torn or cut by user's hand or hands exactly transversely to the longitudinal direction of the tape without being torn zigzag or in a slanting direction.
