Abstract
Abstract A magnetic tape cassette in a case overwrapped with a plastic film having a tear tape wound on all four sides of the case close to, and substantially in parallel with, one case end, the film being overlapped at the mating edge portions and glued together on a side of the case adjoining to the above end, with the tear tape extended between the overlapped edge portions, is characterized in that at least one cut is made in the overlying one of the edge portions, extending along the edge of the tear tape closer to one case end and, where an additional cut is provided, the latter extending obliquely away from the end of the opposite edge of the tear tape. The underside of the end portion of the tear tape and, when desired, the same side of the overlying film edge portion, are made adhesive-repellent. The end portion of the tear tape may extend beyond the overlying film edge portion.
