The present invention relates to a method for producing a laminated material for labels.

Transparent, pressure-sensitive labels, in particular beer labels, often have the following structure: substrate film of polyethylene terephthalate (PET) cover one side of a dividing structure, typically a silicone polymer, which is coated with adhesive, pressure-sensitive. This adhesive, pressure-sensitive, dried at elevated temperature, and then the front material laminated on the adhesive side. The adhesive is then, under the pressure of the lamination process, goes to the film face of the material. Film face material is generally transparent polypropylene film with a thickness typically between 20 and 60 microns.

This adhesive design, then cut into narrow given bandwidth, suitable for further transformation of a pressure-sensitive label printer. The next step in the method of producing a label is that the label printer prints flat transparent film is not sensitive to pressure on the back, usually a film of biaxially-oriented polypropylene (BOPP) or film of PET, then this sealed foil laminate with a suitable adhesive for laminates to design, sensitive to pressure, fasting is caused by the manufacturer of label material. This laminated material usually has a thickness of between 12 and 40 microns.

This film is printed on the reverse side to ensure the paint abrasion resistance, in addition to the fact that shiny silver and gold metallic colors required by the owners of the brand, in this case, Breweries, can be achieved only when the silver paint solvent-based printed gravure printing on the reverse side of a transparent film, which, when viewed from above, gives high brightness, required for metallic pigments, shining through the transparent film.

Used adhesive for laminates is usually polyurethane adhesive, often based solvent, which is an environmental hazard, as well as the risk of explosion and fire. This whole process is complex, bulky and expensive.

U.S. patent 6540865 reveals the substrate covered by the separating means and, then, coated with adhesive, over which a second layer, reducing stickiness, applied to the surface of the adhesive, pressure-sensitive, forming a continuous film covering the adhesive layer, pressure-sensitive. This non-adhesive layer allows you to roll the design and save. The layer can then be activated by heat for subsequent lamination n the other substrate.

This layer, which reduces the stickiness, having a density of 10-15 g/m2and preferably containing hot-melt polyamide resin, very expensive, adding significantly to the cost and complexity of the full design.

In the way of commercial printing operating at normal speed process, the activation of such a layer, which reduces the adhesion and the subsequent laminating on the transparent plastic film will not lead to completely transparent, colorless film without flaws, which requires beer industry for transparent labels.

Patent WO 99/149440 open design, pressure-sensitive, in which the adhesive is pressure-sensitive, applied on the adhesive surface of the substrate and on top of the adhesive, pressure-sensitive, put nesipuosia not educated in advance of the film material, which covers the pressure-sensitive layer, making it non-adhesive. The respective film-forming materials include thermoplastic polymers, such as polyolefins, PVC skin, polyesters, or polyamides, which could be covered by extrusion or applied in a liquid or molten state on the upper surface of the adhesive is pressure-sensitive.

This structure, which includes a substrate, adhesive, pressure-sensitive, and a layer of a solid film, the go such to be suitable for printing, die-cutting stamp, removal of the matrix, and leave, thereby eliminating the use of conventional face materials. In addition, it may be further laminated pure or pre-sealed transparent laminated film. However, it is extremely difficult and costly production process.

A method of obtaining a laminate label according to the invention includes a transparent plastic film having a first side and a second side, the printing on the second side of the transparent plastic film, ensuring the separation of the substrate, including the separation surface and a single layer of sticky adhesive on the separating surface, the activation of sticky adhesive on the dividing surface so that it becomes sticky, and mounting adhesive adhesive on the separating surface to the second side of the transparent plastic film.

In the present invention the separator substrate cover non-adhesive adhesive to form a single layer of non-adhesive coating that prevents sticking. Covered with adhesive separating the substrate may then be wound, saved as long as you want, and then transferred to the printer for further conversion into sensitive the pressure-layered material for labels.

Non-adhesive adhesive activate to become adhesive by exposure to heat or radiation to the surface of the adhesive. The adhesive may be activated during normal continuous printing and conversion process of the printer at normal operating speeds. After that, the activated substrate, coated with adhesive, pressure-sensitive, laminated on the transparent film, pre-sealed, printer to produce a construction in which the fingerprint is captured between one layer of transparent film, and a single layer of adhesive deposited on the substrate. Transparent, suitable for printing film can be made of polypropylene (PP), a complex of the polyester (PET), PVC skin (PVC), polylactic acid (PLA), polyethylene (PE), cyclic copolymers of cycloolefin (CES), polymers of cycloolefins (PCO) and polystyrene (PS).

Compared with the above described conventional design method according to the invention provides a process simplification and the elimination of one layer of a transparent film and one layer of laminating adhesive. At the same time, the line is very flexible. For example, a transparent plastic film may be printed on the reverse side immediately before the formation of the layered material. In addition, this new solution does not require additional is sustained fashion layer polymeric film-forming materials, put above adhesive layer; rather, the only nesipuosia adhesive layer is converted into the only clear, colorless adhesive layer, pressure-sensitive, which meets the requirements of the brewing industry is relatively transparent labels.

Thermally activated or temperature switchable adhesive could be achieved, for example, but not exclusively, when using a dispersion of acrylic polymer polymerized by the method of core-shell, which will be described below. This polymer dispersion forms a non-adhesive film when dry.

The adhesive may be such that it has a first morphology, which is non-adhesive, and the second morphology, which is adhesive. The adhesive may include particles that have a hydrophobic core surrounded by hydrophilic membranes. For example, the core may include a polymer having a low glass transition temperature, such as adhesives, pressure-sensitive, and the membrane may include a polymer with a high glass transition temperature. Hydrophobic core may also be embedded in a matrix of hydrophilic polymer.

The substrate is covered with adhesive, and thus, the layer film is formed on the substrate. Under the action of the corresponding pulse energy, warmth or near infrared radiation, the morphology of the film narwhals is, and the film becomes adhesive.

Alternatively, this change from the non-adhesive film to a film of adhesive could be achieved using crystallizable polymers with side chain, physical properties, which can vary significantly at a given temperature. For example, non-sticky crystal film may vary on an amorphous adhesive coating, pressure-sensitive, at a certain temperature.

Hereinafter, the invention will be described by example with reference to the attached drawings, in which

figure 1 shows a side view of a bottle labeled

figure 2 shows a side view of a battery provided with a label, and

figure 3 shows a cross-section of the label according to the invention.

Example

The proposed substrate is a paper substrate and a silicone coating. Substrate cover non-adhesive adhesive, dried and roll into a roll. Roll stored in a warehouse until needed.

The adhesive may be an adhesive type core-shell from National starch and chemical company National Starch and Chemical Company) (an adhesive of the type described in application for U.S. patent 2007/0014985), or crystallizable polymer with a side chain, such as adhesives Intelimer® from Landec Corporation, or the adhesive may be of the type described in patent EP 1375358. Patent EP 1375358 describes an adhesive comprising a thermoplastic smo is, solid plasticizer, adhesive agent and water. Typical thermoplastic resin is an acrylic resin, a typical solid plasticizer is inhibited phenol resin, and a typical adhesive means is a resin of ester of rosin. Thermoplastic resin, a solid plasticizer and adhesive means are non-adhesive at room temperature. However, when the adhesive is heated above the melting point of the solid plasticizer, a solid plasticizer is melted and oijala, seeping into thermoplastic resin and anti-adhesive agent. After this anti-adhesive means softens and becomes sticky.

The roll is later used on a printing press, where the transparent surface film and the substrate are attached to each other. To bond these two canvases together transparent surface film is printed on the reverse side so that the desired characters and / or images formed as a mirror.

Non-adhesive adhesive activated, for example, by applying heat, infrared radiation, or other suitable method. Activation makes the adhesive tacky. After activation of the adhesive transparent surface film attached to the adhesive substrate. The resulting layered material cut out the stamp and unnecessary matrix is removed so as to form indiv the dual label on the substrate.

Labels are particularly useful, for example, in bottles, especially in the beer bottles. Used in beer bottles shown in figure 1. Beer 1 bottle labeled 2, one on the neck of the bottle and the other on the lower part of the bottle. Labels can include prints and / or images as desired.

Another application of the labels of batteries, such as labels, which form the outer shell of the battery. The use of labels in the battery shown in figure 2. Battery 3 with poles 4, 5, wrapped with label 2, which includes prints and / or images.

The overall structure of the label 2 to the substrate is illustrated in figure 3. Label 2 includes a transparent plastic film 2a, the printed layer 2b, including prints and / or images, and the bonding layer 2c comprising a single layer of adhesive. The adhesive is such that it can be activated so that its behavior has changed from the non-adhesive to adhesive.

The substrate 6 is located below the label 2. The substrate 6, such as a PET substrate or paper, provide a siliconized layer 6a. The substrate 6 may be a continuous canvas on the surface of which is applied a sequential labels.
