Description

Technical field

The present invention relates to a label for reclosing a package. The present invention also relates to a method for producing reclosable labels, and to rolls on which reclosable labels are wound. Furthermore, the present invention relates to packaging, the dispensing or removal opening of which is covered by a reclosable label according to the invention.

State of the art

Usually, packages are opened by opening a seal, seal or glue, so that the package is opened irreversibly. As a result, it cannot be closed again without additional aids such as plastic clips.

There is a great need for systems to equip these packagings in such a way that parts of the contents can be removed several times from them and these can then be resealed.

In this regard, there are various systems on the market, all of which are limited in their suitability.

Single-layer labels are used, for example, to open and reclose such packaging. These are applied or labeled via a dispensing or removal opening that has been pre-cut into the packaging, from which parts of the content are later removed from the packaging. By pulling off the resealable label, the dispensing or removal opening is released, since the part of the packaging that still closes the pre-cut dispensing or removal opening adheres to the label. In order to ensure the freshness and / or the hygiene of the packaging content, the label as a reclosable label can be brought over the exposed dispensing or removal opening after removal of parts of the packaging content and pressed onto the top of the packaging, as a result of which it sticks to it.

Usually reclosable labels have a handling segment, i.e. a specially designed area of the label where a consumer can grab the label, pull it open and, if necessary, reclose it.

Despite the special shape of the handling segment, it can be difficult to grasp at all, because it lies flat on the packaging due to the manufacturing process. A consumer therefore often requires several gripping attempts and / or has to use a fingernail to lift and grasp the handling segment.

Common methods for producing more tangible handling segments of a reclosable label consist in making the handling segments slightly protruding from the packaging surface so that they no longer lie on the packaging surface and thereby a space is released between the handling segment of the label and the packaging. Processes such as slitting the label material, applying lacquer or additional material layers with curvature or pre-tensioning are used. The disadvantage of these methods is that the effect of lifting the handling segment off the packaging surface is uneven and inconsistent. In addition, the labels are generally wound on rolls at the end of the production process, as a result of which a not insignificant pressure acts on the handling segments until they are applied in the subsequent processing step over a dispensing or removal opening.

task

The object of the present invention is therefore to provide a reclosable label with a handling segment which sticks out from the packaging in a permanent and elegant manner and is therefore easier for a consumer to grasp. Furthermore, the invention relates to a simple method for producing such labels with a protruding handling segment.

Disclosure of the invention

This object is achieved by a reclosable label according to claim 1. Subclaims 2 to 8 relate to advantageous developments of the subject matter of claim 1.

A reclosable label according to the invention contains a flat base body and a surface section of the base body, hereinafter referred to as the handling segment. Between the handling segment and the base body, a transition zone along at least one at least line-shaped embossing area is permanently embossed, at least in sections, so that the handling segment, in relation to the level of the base body, protrudes in a stable and dimensionally stable manner for easy gripping. The embossing, at least in sections, is formed by at least one thermomechanically deformed region.

The shape of the label, as well as the base body and the handling segment, can be changed as required, i.e. can be varied depending on the necessary delivery or removal opening of a packaging. The labels can accordingly be circular, for example with a diameter of 30 mm, oval, polygonal or rectangular and square, the latter also being able to have rounded corners.

In the course of the embossing, the embossing edge or embossing surface of the heated embossing tool of an embossing unit is pressed briefly into the deformable material of the label under a defined pressure and a defined temperature. The label lies, for example, on a flat, non-deformable surface with a recessed area into which the embossing tool presses the deformable material at the level of the transition zone of the label, or on a flat, deformable surface into which the heated embossing tool bears the deformable material at the level of the transition zone of the label. The embossing edge or embossing surface can have different shapes, as will be explained in more detail below. When the embossing edge penetrates into the deformable material of the label, material is displaced and a pressure in the material opposite to the direction of displacement as A counter reaction to the embossed embossing edge occurs. After the embossing edge has been removed from the deformed material, the counterpressure generated in the material relaxes in the direction of the penetration point of the embossing edge, as a result of which the handling segment, which is smaller in terms of area and weight, moves in the direction of the base body until the pressure generated in the material is completely reduced. The angle of the embossing edge, the embossing time and the embossing pressure are consequently the parameters with which the protrusion of the handling segment can be set.

Assuming that at least one layer of the label is a material that can be deformed better by heating, heating the embossing tool means that the embossing pressure can be reduced, which improves the embossing quality of the label. The temperature of the embossing tool and the embossing pressure can be coordinated with one another, so that the required protrusion of the handling segment arises on the one hand through thermomechanical embossing and on the other hand the material layers below the embossed layer are protected.

As an example of a material to be embossed, thermoplastics are mentioned which are solid in their use temperature range and can be brought into a thermoplastic state by heating, in which they are soft and not dimensionally stable. In this state, they are deformable. After subsequent cooling, the thermoplastics become solid again and retain a deformation created in the thermoplastic state.

In summary, the embossing process according to the invention thus comprises melting or softening the label in the transition zone, deforming under a defined force in the transition zone to form a handling segment and then cooling to maintain the deformed state.

In addition to heating the embossing tool, it is also conceivable for the section to be embossed to be heated in the transition zone between the base body and the handling segment at the same time or immediately before the embossing by a laser, the thermal diffusion length of which is matched to the material layers of the label.

It is also conceivable that several lines are embossed at a defined distance from one another in the transition zone. Also, the lines do not have to be embossed continuously in order to achieve the desired effect of the handling segment sticking out. A curved or partially curved embossing is also advantageous, as a result of which, depending on the radius of curvature, the protrusion of the handling segment receives additional shape-related protection against sinking onto a packaging surface. In addition, the label due to the protruding due to the curved, thermomechanical embossing, arcuate handling segment easier to grasp. Combinations of curved and rectilinear thermomechanically deformed embossed sections are also conceivable, the combination of rectilinear and curved embossed sections making it possible, for example, to specify an advantageous hand position for gripping the handling segment. Furthermore, the line-shaped embossing area can also be a line that is partially thickened.

Constant protrusion is understood to mean that the handling segment stably and permanently protrudes from a packaging surface, that is to say that both winding up on rolls following a manufacturing process of the label or the like, as well as repeated pulling and resealing of the label, the protrusion or through the embossing generated, fixed angle between the base body and the handling segment almost does not affect.

The angle created by the embossing between the base body and the handling segment is between 3 ° to 60 °, preferably between 3 ° to 35 °, and further preferably between 3 ° to 15 °, the angle in the manufacturing process depending on the physical conditions (e.g. Size of the index finger and thumb) of the consumer group associated with the package content.

The thermomechanical deformation in the transition zone between the base body and the handling segment can be carried out with a flat bed embossing unit, the temperature of the heated tool being in the range from 40 ° C. to 200 ° C. or in the range from 60 ° C. to 190 ° C. and preferably in Range is from 80 ° C to 180 ° C.

The tool is guided against the counterpart or the counter surface with a defined embossing force. Blind embossing, i.e. the tool is pressed against a flat counterpart, or relief embossing with a male and female die can be used.

The thermomechanical deformation of the transition zone can also be carried out by a rotary embossing unit in addition to a flat bed embossing unit.

In an advantageous embodiment, the handling segment of the label can also be thermomechanically embossed, at least in part, with a pattern that can reinforce the shape, support the handling and / or enhance the appearance. It is conceivable that the additional thermomechanical embossing is carried out in a further upstream and / or downstream embossing unit or that in one embossing unit at least two heated embossing tools, which run in the running direction of the material web to be processed are offset from one another, so that two successive labels can be thermomechanically embossed at the same time, one label being embossed in its transition zone to form the handling segment and the other label being thermomechanically embossed with a pattern.

The base body and the handling segment preferably contain one or more layers.

The layers can consist of different materials, for example a printing material, also called a backing layer or backing, to which a self-adhesive coating can be applied, and a release material, i.e. a release paper or film.

Papers or various foils are available as carriers for the label, foils are preferably used.

One or more carrier layers can be printed on the top and / or bottom. The printing can be done with one of the usual printing processes such as gravure, flexo, offset, letterpress, screen printing or digital printing.

The materials used for the layers can also be transparent, white, metallized or otherwise colored.

In the case of a multilayer structure, the individual layers can be formed from the same material, or else from different materials. Likewise, the individual materials in a multilayer composite can have the same color, but different colorations can also be combined, so that, for example, a white base film layer is covered with a transparent second film layer.

Preferably at least one of the layers contains a thermoplastic, e.g. Polypropylene (PP), polyethylene terephthalate (PET) or polyethylene (PE).

Layers of monoaxially and biaxially stretched films based on polyolefins, or films based on stretched polyethylene or stretched copolymers which contain ethylene and / or polypropylene units, or, if appropriate, also PVC films, PET films, films based on vinyl polymers , Polyamides, polyesters, polyacetals, polycarbonates can be used.

Biaxially oriented polypropylene is characterized by its very high tensile strength and low elongation. Biaxially stretched films based on polypropylene are preferably used for the production of the reclosable labels according to the invention. The thicknesses of the biaxially stretched films based on polypropylene are between 20 and 100 μm or between 25 and 75 μm and preferably between 30 and 65 μm. Biaxially stretched films based on polypropylene can be produced using blown film extrusion or using conventional flat film lines. Biaxially stretched films are produced in one or more layers. In the case of the multilayer films, the thickness and composition of the different layers can be the same, but different thicknesses and compositions are also known. Single-layer, biaxially or monoaxially stretched films or multilayer, biaxial or monoaxial films based on polypropylene, which have a sufficiently strong bond between the layers, are preferred, since delamination of the layers during use is disadvantageous.

Films based on hard PVC or based on soft PVC are also suitable. When using films based on rigid PVC, the film thicknesses are between 20 and 100 µm or between 25 and 65 µm and preferably between 30 and 60 µm.

Polyester-based films, for example polyethylene terephthalate, are also known and can also be used to produce the labels according to the invention. The thicknesses of the films based on PET are between 20 and 100 μm or between 25 and 65 μm and preferably between 30 and 60 μm.

In a further advantageous embodiment, at least one of the layers can also contain a metal layer or a metallized layer.

Even a thin metal layer or a metallized layer can be thermomechanically deformed with an embossing unit such that a handling section forms a permanent angle to the base body or to the packaging surface for easy gripping of the handling segment.

The release material is usually a silicone release layer. Its job is to carry the reclosable label during manufacture and to protect its adhesive layer from contamination. The silicone release material also serves as a punching pad during the punching process of the labels.

The release material is used both as release paper and as release film.

In the form of a release paper for reclosable labels, satin-coated kraft papers are known. Coated papers are also used. Plastic-coated paper is also used for special requirements, such as insensitivity to moisture.

On the other hand, plastic films can be selected as release films if the later application is subject to special requirements. A release film that is siliconized on one or both sides can be used as the release film, preferably with a thickness between 23 and 36 μm.

However, it is also conceivable on one and both sides with a corresponding separating layer from sheet materials such as PP or the like and paper, each with a preferred thickness between 20.0 and 40.0 microns.

The underside of the flat base body preferably also has at least one single or multiple removable adhesive layer.

This layer of adhesive can be applied over the entire surface or only partially on the underside. The layer of adhesive preferably does not reach the transition zone, so that adhesive does not swell under the handling segment during the embossing process.

In the event that the adhesive also has to be applied to the underside of the handling segment due to the manufacturing process, the adhesive force in the area concerned can be reduced for the purpose of trouble-free opening and reclosing of the packaging. Either the underside of the handling section with adhesive can then be covered with a release paper or the adhesive is neutralized, for example by printing or powdering.

The layer of adhesive preferably contains a pressure sensitive adhesive. A pressure sensitive adhesive is a viscoelastic mass that remains permanently sticky and tacky when dry at room temperature. Glue is applied immediately to almost all substrates by applying light pressure.

The pressure sensitive adhesive contained in the adhesive layer can be applied to the carrier as an aqueous dispersion adhesive or as a solvent-containing system. So-called "hot melts" are preferably used, including those which are cured with UV radiation after application from the melt.

The adhesive is preferably such that it retains its original adhesive strength even after being pulled off and reattached several times.

The pressure sensitive adhesive is preferably one based on natural rubber, PUR or acrylates, which may contain styrene-isoprene-styrene block polymers. A UV-crosslinkable acrylate hotmelt pressure-sensitive adhesive mixed with additives and resins is preferably used.

The adhesive application is between 5.0 and 50.0 g / m ² or between 10.0 and 30.0 g / m ² and preferably between 15.0 and 25.0 g / m ² , the latter range of values in the Usually corresponds to an adhesive layer thickness of 15 to 25 µm.

On the underside of the detachable adhesive layer, a further permanent adhesive layer can also be applied, at least in part, whereby the label is secured against complete detachment from a packaging. The permanent adhesive layer then acts as a hinge when opening and reclosing.

A lamination adhesive layer and / or a further printed layer is preferably arranged between two outer layers of the reclosure label.

If a multi-layer composite is used, the layers can be connected to one another with a lamination adhesive which is applied between the layers. Any common laminating adhesive can be used as the laminating adhesive, for example water-based acrylate adhesives, water-based solvent adhesives, two-component adhesives based on polyurethane, hot melt adhesives based on rubber or acrylate, UV-curing adhesives based on rubber or acrylate, etc.

In a further advantageous embodiment, one or more handling segments are arranged on one or more side edges of the reclosable label, with which the reclosable label can be opened and reclosed in different directions. In addition, with regard to the reclosable label, a handling segment can be located exactly on the side edge that is most convenient for use.

However, a handling segment can preferably also be arranged at one or more corners of the reclosable label.

According to the invention, the object is further achieved by a packaging which has a packaging body with a dispensing or removal opening and a contains reclosable label according to the invention. The resealable label sticks to the packaging. The base body of the reclosable label closes the dispensing or removal opening of the packaging. At least part of the handling segment protrudes from the packaging surface for easy gripping.

Packaging can be, for example, flexible packaging in the form of tubes, stand-up and block-bottom bags or deep-drawing trays or folding boxes or any type of packaging that is made from sheet-like materials such as foils, composites or paper and cardboard.

In an advantageous embodiment, the dispensing or removal opening is released by pulling off the base body of the reclosable label by means of the handling segment from the packaging surface.

According to the invention, the object is further achieved by a roll which comprises a release material and a plurality of reclosable labels according to the invention. The resealable labels stick to the release material. The resealable labels can preferably be applied equidistantly with respect to the roll direction of the roll on the release material. Reclosure labels of the same type are preferred, i.e. the shape and structure are the same, wound on the roll.

Description of an embodiment

A reclosable label according to the invention, which is described further below with reference to the figures, enables easy gripping by the handling segment protruding from the packaging surface, which has been permanently shaped by a thermomechanical deformation.

When embossing, the embossing edge or embossing surface of the heated embossing tool of an embossing unit is pressed briefly into the deformable material of the label under a defined pressure and a defined temperature. The label lies on a flat, non-deformable surface with a recessed area into which the embossing tool presses the deformable material at the level of the transition zone of the label, or on a flat, deformable surface into which the heated embossing tool places the deformable material Height of the transition zone of the label. The embossing edge or embossing surface can have different shapes, as will be explained in more detail below. When the embossing edge penetrates into the deformable material of the label, material is displaced and a pressure in the material opposite to the direction of displacement occurs as a counter-reaction to the embossed embossing edge. After the embossing edge has been removed from the deformed material, the counterpressure generated in the material relaxes in the direction of the penetration point of the embossing edge, as a result of which the handling segment, which is smaller in terms of area and weight, moves in the direction of the base body until the pressure generated in the material is completely reduced. The angle of the embossing edge, the embossing time and the embossing pressure are consequently the parameters with which the protrusion of the handling segment can be set.

Heating the embossing tool for thermomechanical deformation also has the consequence that the embossing pressure can be reduced, which improves the embossing quality of the label. The temperature of the embossing tool and the embossing pressure can be coordinated with one another, so that, on the one hand, the required protrusion of the handling segment is set by the thermomechanical embossing and, on the other hand, the material layers below the embossed layer are protected due to the reduced pressure.

In Fig. 1 a resealable label 100 is shown in a top view. In the following, the horizontal dimension is referred to as the length or longitudinal direction of the label, and the vertical dimension is consequently referred to as the width. The rectangular label 100 is subdivided into a flat base body 102 and a handling segment 104. A transition zone 103 is located between the base body 102 and the handling segment 104. Within this transition zone 103, a heated embossing unit acts with pressure on the material of the label 100 and forms one thermomechanically generated stamping line 106.

The embossing does not have to, as in Fig. 1 shown continuously, but can also, as in the case of Fig. 2 done only in sections. It is also conceivable that at least two embossments 106a and 106b take place horizontally spaced in the transition region 103, as in FIG Fig. 3 you can see. Different parameters can be used in relation to the embossing unit for the at least two embossments 106a and 106b in order to be able to better adjust the protrusion of the handling segment 104.

A curved embossing 106 as in FIG Fig. 4 be. The curved or arc-shaped embossment 106, which is symmetrical to the central axis of the longitudinal direction, ensures that depending on the radius of curvature, the protrusion of the handling segment 104 provides additional shape-related protection against sinking onto a packaging surface receives. In addition, the sheet-shaped handling segment 104 which projects as a result of the thermomechanical embossing further facilitates gripping the label 100.

Furthermore, it is also conceivable that the line-shaped embossing area of the embossing 106 is a line that is partially thickened.

Fig. 5 also shows a partially curved embossing 106. A first embossing section 106c runs in an arc shape in the horizontal direction up to the center of the label and in the further half there follows a straight embossing section 106d. Other combinations of curved and straight embossed sections are also conceivable. The combination of embossed sections allows, for example, the hand position to be gripped to grip the handling segment.

In Fig. 1 the handling segment 104 is located on one of the two short sides of the rectangular label 100, although other designs are also possible. As a result, a handling segment 104 can also be located at one or more corners.

It is also conceivable that the handling segment 104 has a smaller or larger width than the base body 102.

Fig. 6 shows the section along the line A - A in Fig. 1 . It can be seen that a resealable label 100, in addition to a base body 102 and a handling segment 104, also has adhesive layer 108 on the underside of the base body 104, through which the label 100 can be attached to a packaging surface. The handling segment 104 is adhesive-free on its underside. The embossing 106, which is generated by a thermomechanical deformation, means that the handling segment 104 forms an angle α with respect to the base body 102 that is less than 180 °. Due to the embossing 106 between the base body 102 and the handling segment 104, the corresponding material layer is thinner than in the area of the base body 102 and the handling segment 104, since material has been displaced.

The position of the base body 102 and the handling segment 104 can consist of metallized polyester with a thickness of 50 μm.

The adhesive of the adhesive layer 108 advantageously retains its adhesive force even when it is peeled off and closed again several times, the adhesive being able to be of any conventional type, such as, for example, an aqueous adhesive, a solvent-based adhesive, a hot-melt adhesive or a UV-radiation-curing hot-melt adhesive.

Fig. 7 shows a further sectional view of a label with other layers. A printed layer 114 and a laminating adhesive layer 116 are introduced between the two carrier material layers 110 and 112. In addition, there is a further, permanent adhesive layer 118 below the detachable adhesive layer 108, which permanently secures the label 100 on a packaging surface. The permanent adhesive layer 118 covers only a part of the underside of the base body 102, so that the label 100 can be detached from a packaging surface and applied again, but is also secured against complete removal of the label. The permanent adhesive of the adhesive layer 118 can have a higher adhesive strength than the adhesive layer 108. The area of the permanent adhesive 4 thus has the function of a hinge between a packaging and the label 100.

The upper substrate layer 110 can consist of biaxially stretched, transparent polypropylene with a thickness of 20 to 50 μm and the lower substrate layer 112 can consist of biaxially stretched metallized polypropylene with a thickness of 50 μm. A layer of laminating adhesive may be located between the top layer 110 and the bottom layer 112. Any suitable adhesive, such as, for example, an aqueous acrylate adhesive, a UV-curing acrylate adhesive, a solvent-based adhesive or a hot-melt adhesive, can be used as the laminating adhesive 116.

In Fig. 8 the label 100 is glued to a packaging 120. The packaging 120 has a punched hole 122 which is covered by the base body 102 of the label 100. The punched hole can be continuous, continuous or just perforated. By gripping the handling segment 104, the label 100 can be detached from the packaging 120, preferably in the longitudinal direction, as a result of which the dispensing or removal opening 121 is opened.

When the label 100 is peeled off, the part 120b of the packaging which lies within the punched hole 122 adheres to the adhesive layer 108 of the label 100, as in the sectional view in FIG Fig. 9 along the line B - B Fig. 8 you can see.

Fig. 10 finally shows schematically the manufacturing process of a reclosable label 100 according to the invention in an exemplary machine 200.

A starting material web 204 is unwound from a roll 202 and conveyed in the longitudinal direction D. The starting material web 204 contains the backing material layer, which is made, for example, of a metallized polyester, and an adhesive layer 108 applied to the underside of the backing material layer, which in turn is protected on its underside by a separating material. The release material can, for example, be a release liner siliconized polyester or glassine. In a further advantageous embodiment, the layer of adhesive and the separating material layer of the carrier material layer to form the starting material web 204 can also be added only within the machine 200.

In a first processing step, the starting material web 204 is fed to one or more printing units 206 and printed. Printing takes place, for example, in flexographic printing, gravure printing, offset printing, screen printing, digital printing or in another known printing process.

The printed material web 208 then passes into a punching unit 210, in which the reclosable labels are punched in the predetermined shape. The carrier material and the adhesive are cut through, but not the separating material or the release material.

From the punched material web 212, e.g. a residual material web 216 is sheared off by means of a shearing roller 214 and wound onto a roller 218.

The release material web 220 with the stamped labels on the upper side then arrives in an embossing unit 222. An embossing 106 is produced there within the transition zone 103 by thermomechanical deformation. The end material web with the reclosable labels according to the invention is then wound onto a roll 226.
