Definitions

  • Tamper-evident tape has existed for some time and consists of adhesive tape with markings that transfer onto an underlying packaging if the tape is removed after application, providing a visual indication that the packaging has been tampered with.
  • the laser-imageable layer being formed within the adhesive layer means that it is a part of the adhesive layer, in other words, the laser-imageable layer is integrally formed within an adhesive layer.
  • the laser imageable layer may comprise an adhesive and a laser imageable composition within the adhesive. As indicated above, irradiation with a laser can occur before the customisable tape is applied to the packaging container such that the image is at least partially transferred onto the packaging container.
  • the information provided in the custom image is applied at the point the package is sealed.
  • an accurate date/time stamp may be applied at the stage when it is known that the package has been sealed with the correct contents, improving the traceability of any theft from within the package.
  • Irradiation after application also allows for flexibility in the preparation of the tamper-evident packaging as the images may be applied to each package, via the laser irradiation of the laser-imageable layer of the tamper-evident tape, at the time of packaging. This allows for a change in the order of packages being packaged, or packaged without significant for-warning, without the hassle or waste of pre-imaged and stored tamper-evident tape.
  • the laser-imageable layer in the customisable tape may be formed in an adhesive layer. This allows for easy transfer of the image onto the packaging as well as a simplified manufacturing process of the tape itself as fewer discrete layers are required to be combined to create the tape. It may also allow for a thinner tape profile as two tape features are combined into a single tape layer.
  • the laser-imageable layer in the customisable tape may be formed in the substrate.
  • Customisable tape preferably comprises a substantially flat, long, and thin shape.
  • the customisable tape is preferably configured such that, when it is tampered with, such as being peeled off the surface that it was applied to, it provides an indication that tampering has occurred.
  • the terms “custom tape”, “customisable tape”, “tamper-evident tape”, and “laser-irradiated tape” are interchangeable in relation to the claimed invention.
  • a packaging container may comprise any container, such as a box or cylinder, for containing goods which are to be delivered.
  • a packaging container may be a vial, an ampoule, a bottle, a syringe, a tube, a cartridge, a pallet, a jar, or other such containers.
  • the packaging container is used as, or part of, a pharmaceutical or cosmetics packaging.
  • a packaging container may be made of cardboard, plastic, or metal, for example.
  • the packaging container may be made of glass.
  • the packaging container is made of medical grade materials.
  • the packaging container may be made of a mixture of any of the above discussed materials; for example, a glass vial or tube with a plastic cap can be sealed by the tape being applied over both.
  • the tape is configured such that it is not irradiated, or only partially irradiated, before it is applied to the packaging container to seal it. As discussed above, this means that the information provided in the custom image can be applied at the point the package is sealed.
  • an accurate date/time stamp may be applied at the stage when it is known that the package has been sealed with the correct contents, improving the traceability of any theft from within the package.
  • Irradiation after application also allows for flexibility in the preparation of the tamper-evident packaging as the images may be applied to each package, via the laser irradiation of the laser-imageable layer of the tamper-evident tape, at the time of packaging. This allows for a change in the order of packages being packaged, or packaged without significant for-warning, without the hassle or waste of pre-imaged and stored tamper-evident tape.
  • the packaging container may be suitable for containing medical pills, liquids (preferably: parenteral preparations, oral liquid pharmaceuticals, topical or ophthalmic liquids, or inhalable liquids), medical equipment, bio-hazardous material, a combination of the above, or other such medical goods and apparatuses.
  • liquids preferably: parenteral preparations, oral liquid pharmaceuticals, topical or ophthalmic liquids, or inhalable liquids
  • medical equipment preferably: parenteral preparations, oral liquid pharmaceuticals, topical or ophthalmic liquids, or inhalable liquids
  • bio-hazardous material a combination of the above, or other such medical goods and apparatuses.
  • the laser-imageable layer may be any such layer which, when irradiated by a laser, produces an image which remains once the irradiation process has been completed.
  • the laser-imageable layer may comprise a laser-imageable composition (also referred to herein as a laser-markable material or laser- imageable ink).
  • a laser-imageable composition also referred to herein as a laser-markable material or laser- imageable ink.
  • solvent-based or water-based ink formulations can be used. Particular preference is at present for nitrocellulose/polyurethane- based ink or a PVB-based ink, as this affords good laser imaging performance, adhesion to the substrate and environmental stability.
  • Ink compositions comprised of acrylic, methacrylic, styrenic, acetate, urethanes, imides, cellulosic, vinyl, and binder systems, amongst others, can also be utilised.
  • a particularly preferably laser-imageable composition is AOM (ammonium octamolybdate).
  • the tape substrate may be understood to be the top layer of the tape, or the top layers of the tape generally, which does not provide the adhesion between the tape and the package.
  • the laser imageable layer may be incorporated into the substrate layer, or can be between the substrate and adhesive layer, or can be incorporated into the adhesive layer.
  • the substrate can also be understood to be the portion of tape which is peeled off the package during tampering.
  • removal of the customisable tape may comprise removal of a portion of the tape, i.e. one or more layers of the tape, particularly the substrate layer. This may leave one or more layers of the tape, such as an adhesive layer including a portion of the image, on the application surface (packaging container)
  • a tamper-evident functionality can be understood to be a feature which demonstrates to an observer, for example, a delivery driver or end recipient of the package, that the package has been tampered with.

  • the tape substrate may be made from paper/tracing paper such as vellum.
  • Other polyolefins such as polyethylene and copolymers, polyester such as PET, vinyl polymers such as PVC, or any other suitable polymer known to those skilled in the art can be used.
  • the image being partially transferred to the packaging container can be understood to mean that once the customisable tape substrate has been removed at least part of the image remains on the packaging container, this can be from residue left after the tamper-evident tape substrate layer has been removed, for example.
  • the adhesive may be solvent-based or water-based.
  • the adhesive may also be applied via a melt process.
  • the laser-imageable layer preferably comprises a laser- imageable composition.
  • Compositions imageable with UV, NIR or CO2 lasers may be prepared.
  • images can be written through the substrate or adhesive layer without compromising integrity; preferably such that the process does not distort or puncture the substrate or adhesive layer.
  • the tape is an adhesive tape, e.g. an adhesive-coated fastening tape used for temporary or, in some cases, permanent adhesion between objects.
  • the tape can be single or double-sided.
  • the tape is single sided, which allows the joining of two overlapping or adjoining materials.
  • a suitable laser-imageable composition can also be applied to substrates using a valve jet, inkjet, bubble jet or similar application systems.
  • the laser-imageable composition within the laser-imageable layer can be based on an inorganic or organic colour-former, that can be marked with a CO2 laser, NIR laser, visible laser, or UV laser.
  • An inorganic colour-former can be an oxyanion of a multivalent metal salt, preferred examples being molybdates, tungstates and vanadates.

  • Near-infrared radiation is in the wavelength range of 780 to 2500 nm.
  • a suitable near-infrared laser can be a solid-state, diode, fibre or a diode array system. Whenever a near-infrared laser is employed, it is desirable to add to the laser imageable composition a near-infrared-absorbing component.
  • Preferred near- infrared-absorbing compounds are those that have an absorbance maximum similar to the wavelength of the near-infrared radiation employed and have little or no visible colour.
  • Suitable near-infrared absorbing compounds include but are not limited to the following: inorganic copper salts such as copper (II) hydroxyl phosphate; organic NIR dyes and pigments such as N,N,N’,N’-tetrakis(4-dibutylaminophenyl)-p- benzoquinone bis(iminium hexafluoro-antimonate); non-stoichiometric, reduced or doped inorganic compounds such as reduced indium tin oxide, reduced zinc oxide, reduced tungsten oxide (tungsten bronze), reduced doped tungsten oxide including an inorganic compound of the following formula M x W y O z (where M is at least one element selected from the group consisting of H, He, alkali metal, alkaline earth metal, rare earth metal, rare earth element, Mg, Zr, Cr, Mn, Fe, Ru, Co, Rh, lr, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Al,

  • suitable fluid system examples include water and organic solvents such as ethanol, isopropanol, ethyl acetate and methyl ethyl ketone.
  • the customisable tape is configured such that the image is fully transferred onto the packaging container following application.
  • the image in the customisable tape comprises a computer-readable code.
  • Such a feature has numerous benefits. For example, this allows for the easy scanning, and therefore identification, of a package anywhere along its delivery route.
  • the computer-readable code may also provide an easy means of sharing package-specific information as well as an easy means for reporting any issues with a specific package.
  • the customisable tape is configured such that the computer-readable code on the tape is only partially transferred to the packaging container such that a portion of the images remains on the tape after removal of the tape from the packaging container.
  • a pressure sensitive adhesive can allow for the transfer of the image to differ depending on whether a portion of the tape carrying the image is applied over a void or a surface.
  • the adhesive is arranged such that a portion of the laser imageable composition forming the image is transferred by the adhesive to the packaging container following application of the customisable tape.
  • the customisable tape comprises a release layer positioned between the substrate and the laser imageable layer, wherein the release layer comprises an adhesive with a lower adhesive strength than the adhesive layer.
  • Such a release layer increases the amount of the image transferred onto the packaging after the substrate has been at least partially peeled off. This is because, as the adhesion between the release layer and the substrate is less than the adhesion between the adhesive layer and the packaging, when the substrate is at least partially peeled off there is insufficient force from the adhesion between the release layer and the substrate to overcome the adhesion of a significant proportion of the tape below the release layer. In other words, the layers of the tape below the release layer are more strongly adhered to the packaging then they are to the substrate.

  • the customisable tape comprises a paper layer and the image is created by irradiating the laser-imageable layer through the paper layer.
  • a paper layer provides the benefit of not needing to be removed from paper and carboard packaging in order to be correctly recycled.
  • the paper layer comprises a layer of vellum or tracing paper.
  • the inventors have identified that such paper layers allow the laser imageable composition to be imaged through the paper layer, allowing for a paper substrate and underlying laser imageable layer.
  • the method further comprises creating a first image in a first region of the customisable tape by irradiation with a laser; creating a second image in a second region of the customisable tape by irradiation with a laser; wherein the customisable tape is configured such that the degree of transfer of the image to the packaging container differs in the first and second regions of the tape.
  • the method may comprise creating an image that extends across the first and second regions of the customisable tape. In this way, the degree of transfer varies across the image, meaning it will be separated upon removal of the tape enhancing tamper-evident functionality.
  • the customisable tape comprises a first adhesive in the first region of the tape and a second adhesive in the second region of the tape wherein the adhesive properties of the first and second adhesives differ.
  • the first and second adhesives may be provided within one or more of the adhesive layers, the laser imageable layer, a release layer, so as to provide the differing adhesive properties in the first and second regions of the tape.
  • the first and second adhesives are provided within the laser imageable layer, the tape further comprising a uniform adhesive layer that extends over the first and second regions of the tape.
  • the first region of the customisable tape is configured such that the first image is only partially transferred to the packaging container and the second region of the tape is configured such that the image is substantially wholly transferred or substantially wholly retained on the tape.
  • the first image comprises a computer- readable code that is not readable after removal of the tape and the second image comprises a computer-readable code that is readable on the tape or the package after removal of the tape.
  • a customisable tape for tamper- evident packaging comprises a laser- imageable layer configured such that an image is created in said laser-imageable layer by irradiation with a laser; an adhesive layer, wherein the laser imageable layer is formed within or adjacent to the adhesive layer; wherein the customisable tape is configured such that a created image is at least partially transferred onto a packaging container following application and subsequent removal of the customisable tape from the packaging container.
  • the customisable tape is configured such that the image is at least partially transferred onto a packaging container following application of the customisable tape onto the packaging container and the transferred image remains on the packaging container if a substrate of the tape is removed.
  • the adhesive layer comprises a pressure-sensitive adhesive.
  • the adhesive comprises a hot melt adhesive or a solventbased adhesive or a water based adhesive.
  • the laser imageable layer comprises a laser imageable composition wherein the adhesive is arranged such that a portion of the laser imageable composition forming the image is transferred by the adhesive to an application surface following application of the customisable tape.
  • the customisable tape comprises a paper layer and the laser-imageable layer is formed within the paper layer.
  • the customisable tape comprises a paper layer configured such the laser imageable layer may be irradiated through the paper layer to create an image in the laser imageable layer.
  • the paper layer comprises vellum. It can be understood that vellum can also be called tracing paper. This allows for the properties of tracing paper to be incorporated into the customisable tape.
  • the customisable tape comprises a first adhesive in the first region of the tape and a second adhesive in the second region of the tape wherein the adhesive properties of the first and second adhesives differ such that the degree of transfer of an image created in the first region of the tape differs to that of an image created in the second region of the tape.

  • Customisable tape J is readable after tampering depending on the type of QR code used, and therefore the level of error-tolerance provided.
  • the distinct layer comprising the laser-imageable composition 330 adheres relatively more strongly to the adhesive 230 than to the substrate layer 130, but the difference is not relatively large.
  • a proportion of the laser-imageable composition 330 remains on the package.
  • between 16% and 24% of the image remains adhered to the substrate such that the low error-tolerant QR codes cannot be read, but the high error-tolerant QR codes can.

Abstract

La présente invention concerne un procédé de préparation d'un emballage inviolable et une bande personnalisable (12, 22) pour préparer un emballage inviolable. Le procédé consiste à appliquer la bande sur un contenant d'emballage (10), la bande comprenant une couche adaptée à la formation d'une image par laser (220, 125, 330, 340, 230) et une couche adhésive (220, 225, 230, 240), et la couche adaptée à la formation d'une image par laser étant formée à l'intérieur de la couche adhésive ou de manière adjacente à celle-ci. Une image (13, 23) est créée dans la couche adaptée à la formation d'une image par laser par exposition au rayonnement d'un laser avant ou après l'application de la bande sur le contenant. La bande est conçue de telle sorte que l'image est transférée au moins partiellement sur l'application de suivi de contenant et l'image transférée (16, 26) reste sur le contenant d'emballage si un substrat (120, 125, 130, 140) de la bande, ayant la partie non transférée (15) de l'image, est retiré. Une couche antiadhésive invisible (440, 430) peut être fournie.
