The present invention relates to a peel detection label that is a laminate including a backing, a pattern layer formed in a part of the surface of the backing, and a pressure sensitive adhesive laminate having at least a pressure sensitive adhesive layer (X) and a substrate layer (Y) laminated in this order thereon, and satisfying the following requirement (1), wherein an elastic modulus of the substrate layer (Y) is 10 MPa or more and 800 MPa or less:

Requirement (1): On attaching the peel detection label onto an adherend and then peeling it from the adherend, interfacial peeling occurs between the backing and the pattern layer, whereby the presence or absence of peeling of the peel detection label from the adherend becomes visually detectable.

The invention relates to a smart label and a system that allows the handling of the label. The smart label system is formed by a) a smart label having a hidden message that becomes visible in the event of an attempt to remove the label from an item to which it is affixed; b) a chip with an antenna embedded with the label; c) an electronic mobile device for communicating with the chip; and d) an algorithm on the chip and on the electronic mobile device for unique encoded reading (padlock) encryption.

A cutting plotter film with anti-counterfeit effect includes: a heat-resistant layer; a stripe-embossed layer having releasing property and bonded on the heat-resistant layer, the stripe-embossed layer being formed with a stripe-embossed surface; a character film layer disposed on the stripe-embossed surface of the stripe-embossed layer, having a contact surface in contact with the stripe-embossed surface, the contact surface being formed with anti-counterfeit stripes; and a heat bonding layer disposed on the character film layer. Figures/characters are cut/engraved on the character film layer and the heat bonding layer. The cutting plotter film is placed on a product and heated to transfer and adhere the figures/characters onto the product.

Disclosed is a sealing device for securing a packaging material. The sealing device for securing the packaging material comprises: a tape supply reel for supplying a sealing tape to which an RFID tag has been coupled; and a sealing part for sealing, with the sealing tape, an opening of a plastic packaging material holding a product, wherein the sealing part adheres the RFID tag, which is coupled to one end of the sealing tape having the length for one use, to an adhesive positioned on the other end portion of the sealing tape having the length for one use, wherein the RFID tag is broken by the adhesive strength with respect to the other end portion when the sealing tape sealing the plastic packaging material is torn.

The present invention relates to peelproof security films made from a poly(meth)acrylate, more particularly from a polymethyl methacrylate, which comprises at most 10 wt % of or no impact modifiers. These films are highly transparent, have good printability qualities, and can be applied without intended break points. The peelproof security films can therefore find use in particular in documents, such as passports, for example, in security labels, such as road tax badges, for example, or for product theft prevention, or as price tags. These security labels are further distinguished by good weathering stability and in particular by especially good UV stability. The present invention relates more particularly to the use of these security labels, which have a thickness of not more than 2 mm, comprise at least 80 wt % of polymethyl methacrylate and contain no impact modification particles.

In order to increase the security of value or security documents 100, a multi-luminescent security element 400 is provided which contains at least one first luminescence means 510 and at least one second luminescence means 520. The first luminescence means 510 can be excited under first excitation conditions Sp-1 for the purpose of luminescence, and the second luminescence means 520 can be excited under second excitation conditions Sp-2 for the purpose of luminescence, said second excitation conditions Sp-2 differing from the first excitation conditions Sp-1. The multi-luminescent security element 400 is additionally equipped with at least one absorber means 600 which prevents an excitation of the at least one first luminescence means 510 under the second excitation conditions Sp-2 for the purpose of luminescence.

Disclosed is a sealing device for securing a packaging material. The sealing device for securing the packaging material comprises: a tape supply reel for supplying a sealing tape to which an RFID tag has been coupled; and a sealing part for sealing, with the sealing tape, an opening of a plastic packaging material holding a product, wherein the sealing part adheres the RFID tag, which is coupled to one end of the sealing tape having the length for one use, to an adhesive positioned on the other end portion of the sealing tape having the length for one use, wherein the RFID tag is broken by the adhesive strength with respect to the other end portion when the sealing tape sealing the plastic packaging material is torn.

Labels and multilayer adhesive assemblies and laminates are described that contain one or more tamper indicating layers. After adhering to a surface of interest, upon attempted removal of the label from the surface or other manipulation of the label, the label separates along the tamper indicating layer. One or both exposed faces of the separated tamper indicating layer may include tamper indicating and or authenticity indicating provisions such as indicia to further provide evidence of attempted tampering.

A tape dispensing system includes packaging tape an application apparatus, and an incision element. The application apparatus is configured to apply the packaging tape to a package. The incision element defines a unique pattern, and is connected to the application apparatus. Movement of the apparatus is effective to punch or incise the unique pattern defined by the incision element completely through the packaging tape and into the package as or after the packaging tape is applied to the package.

Various carton sealing tapes are disclosed that have a plurality of security features, at least two of which include nanomarker particles having identification indicia visible under about 100 to about 400 times magnification and taggants visible upon exposure to a pre-selected wavelength outside the visible spectrum included in the same or different layers of the tape structure depending upon the selection of the backing material for the substrate of the tape. The carton sealing tapes are also printable for inclusion of a consecutive sequence of coded identification information in the form of a barcode or a 2D code.
