A winding device includes: a separation unit that separates sheets layered and simultaneously transported; a winding unit that winds one of the sheets separated by the separation unit; and a pressure contact unit that presses the one of the sheets wound by the winding unit from outside of the wound sheet toward the winding unit.

A label is provided that includes layers; a base film, a thermal layer, and a heat-shrinkable layer. This label is adhered to the top seal of a container. When this label-adhered container is heated in a microwave oven, the thermal layer generates heat through microwave absorption, and heat thus generated serves to heat and soften the base film, heat-shrinkable film and top seal. The heat-shrinkable film shrinks under heat, opening notches penetrating through the label. The top seal thus affected by heating is further subject to a stress applied in response to the notches being opened, and a heated and softened portion of the top seal is also affected by an increasingly higher internal pressure. As a result, holes are formed in the top seal.

To provide an adhesive laminate suitable for high-mix low-volume production without blurring of printing due to external rubbing or the like, or a security label using the adhesive laminate. An adhesive laminate comprising at least one laser-printed layer capable of being printed by laser irradiation, wherein the laser-printed layer includes a laser-printed portion and a non-printed portion, an absolute value of a difference between the color L* values of the printed portion and the non-printed portion is 1.0 or more and 10.0 or less, and a pressure-sensitive adhesive layer is provided on at least one surface of the adhesive laminate.

A label construction including a substrate has a first and second opposite side. The substrate includes a layer of microporous film and a layer of elastomeric film. The layer of microporous film and the layer of elastomeric film are laminated together. The label construction further includes one or more layers of functional materials disposed on either or both of the first and second sides of the substrate.

A system and method for manufacturing a strip or label used to place a substantially invisible identifying mark is disclosed. A strip is treated by removing at least one area of a liner element, a film layer and an adhesive layer. Each one of the removed areas is substantially congruent with the other removed areas. A laser or other ablating device is used to remove the areas through vaporization. The strip element is peeled away from the liner element, exposing the adhesive layer. The adhesive layer is thereafter pressed against a substantially flat metal surface. The laminate top coat and the film layer are removed from the object, leaving the adhesive layer in place. The adhesive material is impregnated with a UV sensitive material, but is otherwise invisible.

A medium includes a base layer and a separation layer stacked on each other. Regions are defined along a first direction. The regions include: a first region in which a portion of the medium which is in contact with the separation layer is stickable; a second region in which a portion of the medium which is in contact with the separation layer is non-stickable; and a third region in which a portion of the medium which is in contact with the separation layer is at least partly stickable. Four first vertexes of a first imaginary trapezoid shape which are located on an outer shape of the first region and four second vertexes of a second imaginary trapezoid shape which are located on an outer shape of the third region are symmetric with respect to an axis parallel with a second direction.

A label winding device is for receiving a medium including a label liner and a label member that is removably attached to the label liner and has at least one label portion and a waste portion, separating the waste portion from the label liner at a waste separation portion, and winding the at least one label portion with the label liner. The label winding device includes: a waste winder for winding the separated waste portion; a label winder for winding the at least one label portion with the label liner without the separated waste portion; a waste guide for guiding the separated waste portion to the waste winder; a support for rotatably supporting the waste guide; a sensor for detecting a rotational speed of the waste guide; and a waste break detector for detecting break of the waste portion on a basis of the detection by the sensor.

A method of making a pad of labels comprises: printing display information on a top surface of a substrate; affixing a first layer of lamination material to a bottom surface of the substrate; affixing a second layer of lamination material to the top surface of the substrate, the second layer of lamination material having a release coating applied to a top surface thereof; applying an adhesive strip to a bottom surface of the first layer of lamination material, the adhesive strip being covered by a liner material; cutting the substrate having first and second layers of lamination material affixed into at least one label; removing the liner material to expose the adhesive strip after cutting the substrate into at least one label; and arranging the labels into a pad of labels.

Non-fungible anti-counterfeit photo-chromic nano-micro three-dimensional tags/labels are designed in such a manner that duplication and counterfeiting of the labels are prevented. The label comprises of a frame quick response (QR) code part (103), which surrounds a three-dimensional sticker part, which consists of a foundation paper (113) made of cellulose, a non-fungible three-dimensional (3D) structure and a fade-resistant transparent plastic sheet (201). The structure consists of multi-colored micro particles (107), silica-infused 3D macro particles (109) and the photo-chromic nano particles (111). The sheet is laminated on the paper after application of dense coating of particles. The code part contains all information about the sticker part and is scannable by a specific application module, which allows to scan the code part to recognize the data in the code part, to direct the data to a customer's database server, which instantly maps the code data with the scanned image that is stored in its database to verify label authenticity. If the data matches with each other, the backend server sends a message to the application module that the product is genuine. In case of any variation between the scanned and stored data, the system sends a counterfeit alert to the application user, instantly requests to take the GPS coordinates of the location and sends report to manufacturer's designated contact.
