Definitions

  • the invention relates to preparing adhesive tape having a holographic image.
  • Holographic images in the form of a metal laminated between two film layers are frequently used as security devices in many products including, e.g., credit cards, tickets, bus passes and other repeatedly used tokens having monetary value.
  • Box sealing tape is used to secure flaps or covers of a box so that the box will not accidentally open during normal shipment, handling, and storage. Box sealing tape assists in maintaining the integrity of a box throughout the entire distribution cycle.
  • Automatic tape dispensers such as case sealers, e.g., automatic case sealers commercially available under the trade designation 3M-Matic from Minnesota Mining and Manufacturing Company ("3M"), are frequently used in high volume packaging operations to rapidly unwind and apply box sealing tape to a variety of packaging materials. Some automatic case sealers operate at speeds of about 85 ft/min ( 28.3 m/min), while others operate at speeds of up to 150 ft/min (45.7 m/min).
  • box sealing tape is often formulated to exhibit a high unwind force, in part, to prevent the occurrence of overspinning during high speed automatic tape dispensing operations. Box sealing tape that is made with block copolymer based pressure-sensitive adhesive compositions and exhibits a high unwind force, tends to exhibit a shocky unwind.
  • the invention features an adhesive tape that includes: a) a backing that includes a holographic image, where the backing has a first major surface and a second major surface; and b) a pressure-sensitive adhesive composition provided on the first major surface of the backing.
  • the pressure- sensitive adhesive composition and the backing are selected such that the unwind force of the tape is at least about 1.1 N/dm at unwind speeds of about 0.3 m min, and the tape exhibits a smooth release upon unwind.
  • the unwind force of the tape is at least about 1.1 N/dm at unwind speeds of no greater than about 30 m min.
  • the unwind force of the tape is at least about 2.2 N/dm at unwind speeds of no greater than about 30 m/min. In other embodiments, the unwind force of the tape is at least about 4.4 N/dm at unwind speeds of no greater than about 30 m/min.
  • the adhesive tape exhibits a shockiness index of no greater than about 3, preferably no greater than about 2, more preferably no greater than about 1.
  • the adhesive composition includes styrene- isoprene-styrene block copolymer and exhibits a 180° peel adhesion of at least about 20 N/dm to stainless steel.
  • the adhesive tape further includes a low surface energy composition provided on the second major surface of the backing.
  • the low surface energy composition includes a compound selected from the group consisting of silicone polyurethanes, silicone polyureas, silicone polyurethane/ureas, epoxy functional silicones, epoxy styrenated silicones, acrylate functional silicones, silicone grafted copolymers, condensation cured organopolysiloxanes, addition cured organopolysiloxanes, fluorocarbon copolymers, 16-20 carbon alkyl side chain copolymers, and combinations thereof.
  • the invention features an article that includes the above-described adhesive tape, and a dispenser capable of dispensing the tape.
  • the invention features a method of using the above- described adhesive tape. The method includes unwinding a roll of the tape at unwind speeds of at least about 30 m/min.
  • the invention provides an adhesive tape that, when in the form of a roll, exhibits smooth unwind (i.e., a relatively low shockiness index), yet has an unwind force that is sufficient to prevent overspinning.
  • the adhesive tape can be formulated to exhibit these properties (i.e., relatively high unwind force and smooth unwind) at low unwind speeds, at unwind speeds of up to 30 m/min, and preferably at unwind speeds of up to 50 m/min.
  • the invention also provides a holographic imaged backed adhesive tape that, upon unwind, is free from damage (i.e., visually perceptible creasing, distortion and combinations thereof) of the holographic image present on the backing.
  • the adhesive tape of the present invention is particularly useful in box sealing applications and is capable of maintaining the above-described properties while being dispensed from a high speed automatic tape dispenser such as an automatic case sealer.
  • the tape can also perform a decorative function.
  • the adhesive tape features a pressure-sensitive adhesive composition provided on a first major surface of a backing that includes a holographic image.
  • the adhesive tape can also include a low surface energy composition provided on a second major surface of the backing.
  • the adhesive composition and the optional low surface energy composition are selected to provide a roll of tape that: A) exhibits an unwind force that is sufficiently high to prevent overspinning of the roll of tape when the force exerted on the roll of tape to effect unwind is removed, e.g., an unwind force of at least about 1.1 N/dm (1 oz/in), more preferably at least about 2.2 N/dm (2 oz/in), most preferably at least about 4.4 N/dm (4 oz/in)), when measured at an unwind speed of 0.3 m/min, (preferably at unwind speeds of up to 30 m/min, more preferably at unwind speeds of up to 50 m/min); and B) exhibits a smooth unwind.
  • the roll of tape exhibits a smooth unwind at unwind speeds up to about 30 m/min, more preferably at unwind speeds greater 30 m/min, most preferably at unwind speeds up to 50 m/min.
  • smooth unwind it is meant that the unwind is not shocky. Smooth unwind is achieved when the holographic image is not damaged (e.g., distorted, creased, and combinations thereof) upon unwind. Damage to the holographic image manifests itself as noticeable alterations to the holographic image including, e.g., change in reflectivity, the presence of creases, e.g., creases extending in the transverse (i.e., cross) direction of the tape, and other distortions of the holographic image. Damage to the holographic image is determined under normal viewing conditions.
  • the adhesive composition is selected such that it cooperates with the backing to yield a tape system having the aforementioned unwind characteristics.
