ABSTRACT:
The invention provides tape graphics printed on a longitudinally extending strip of packaging film simultaneously with the printing of the rest of the packaging film, the tape graphics strip being subsequently slit away from the rest of the film and applied to the package as part of the sealing tape, thereby eliminating the problem of proper registration of tape graphics when the tape is applied to the package because the tape and the package film are synchronized as each package is fabricated without the accumulation of long term drift between the package film and the tape being applied to it. Since the tape graphics are printed at the same time as the package film, there is no need to have a separate preproduced inventory of customized graphics tape, and the colors of the graphics tape and the rest of the package are perfectly matched. When forming reclosable or easy-opening containers with a tack free flap without graphics, it is no longer necessary to preprocess the pressure sensitive tape to include a tack free flap because the necessary tack free flap can be formed on line with a portion of the package film which has been slit away from the package film and applied to the pressure sensitive tape. Additionally, the packaging provides a hermetic seal and can be provided with a tearstrip package openable feature that discloses whether the package has been previously opened. Moreover, there is no exposed adhesive on either surface of the composite web of packaging material, and it can either be run directly into a packaging apparatus to produce finished packages, or can be spooled for future use. When applying tearstrips to a package, or a reinforcement header strip, or a handle, it is no longer necessary to provide separate materials for the tearstrips, headers, and handles because these materials can be formed directly from the package film itself, thus no longer requiring that separate supplies of these materials be on hand.
