A coextruded elongated tear tape comprises at least one layer of thermoplastic resin material monoaxially oriented in the longitudinal direction of the tape and a layer comprising adhesive. The method of making material for the tear tape comprises coextruding the layers. Apparatus for sealing tear tape to packaging material comprises an ultrasonic transducer and an anvil roll, the anvil roll having indicia representative of information formed in relief on the surface thereof and aligned with the path of the tear tape for embossing the indicia thereon. The embossing method comprises passing tape and thermoplastic resin packaging over the anvil roll and heating them to seal the tape to the packaging and to deform them into the indicia.

摘要:
A system and method for imprinting distinct patterns along a seam by which two or more layered plastic sheets are mutually attached to each other is provided. The disclosed method comprises (i) heating selected contours located across a surface of the layered plastic to a predefined temperature, and (ii) forcing a molding head against the heated surface, wherein the molding member has a face from which a plurality of pressing faces extend towards a common direction, the footprint of which features the desired pattern. A soldering head of the disclosed system has at least one molding member having a plurality of fingers. The footprints of the fingers are geometrically shaped in accordance with the pattern to be imprinted along the seam. Some of the fingers may have sharpened tips. A soldering head optionally comprises a pressing member for pressing against peripheries of the footprints of the fingers located across the surface of the layered plastic. A soldering head may also comprise a mold that has recesses that fit in with the fingers of the respective molding member. The temperatures of both the molding member and of the mold are independently controllable. Such soldering head provides for embossing distinct three dimensional patterns across the soldered layered plastic sheets. Tamper evident packaging such as envelopes are further provided.
