DE102008028075A1 - Two-layered label for opening and closing flexible packings of cheese, has cover label and base label, where adhesive force between cover label and back region of base label is higher than force that is necessary for separating cut-off line - Google Patents

Abstract

The label (1) has a base label (3) and an adhesive layer (5) formed at a lower side of the base label. A cut-off line (33) divides the base label into a front region (31) and a back region (32). A lower side of a cover label (2) is equipped with another adhesive layer (4). The cover label is stuck together on the base label by the adhesive layer (4). Adhesive force between the cover label and the front region of the base label is adjustable. Adhesive force between the cover label and the back region of the base label is higher than force that is necessary for separating the cut-off line.

Description

The The invention relates in particular to an at least two-layered label for tearing and reclosing flexible Packaging and its use. Contain such packaging for example, cheese slices or cheese pieces.

One Label (from french etiquetter, from estiquier = stuck), originally notes with hints in the Spanish court ceremonial, is a sign especially on the packaging of a product, which serves as an information carrier. Technical labels are used in many areas for high quality applications used as nameplates for vehicles, machinery, electrical and electronic apparatus, being control labels for process flows, as warranty and inspection labels as well as closure labels.

To open and closing flexible packages such as tubular bags with pre-cut opening containing, for example, wet wipes usually single-ply labels are used.

In the packaging film of the tubular bag is a lid that the later opening hole forms, perforated. By the opening hole can be the wet wipes be removed. The hole is covered with the label, and upon first opening, the perforation of the lid is torn open, that is, the piece of film forming the lid sticks to the bottom of the label.

The Most labels have a grip tab that is either adhesive-free or whose adhesive has been neutralized. To prevent that the label when opening the packaging completely removed from the bag, most of these labels a curved punching that leads to a certain Resistance arises when you open the label up to there Has. The resistance indicates that you should not move on. A another way to prevent the label completely is deducted, consists in the use of two different Adhesives: Removable in the area where the label is should be deducted from the packaging film (opening the packaging), permanently hinged to the full Prevent detachment.

These Labels for wet wipe packaging exist of three consecutively arranged, different zones: Zone 1 non-adhesive, zone 2 detachable adhesive, zone 3 permanent adhesive.

In the EP 0 331 027 A1 a resealable dispensing container for oil impregnated wet wipes is disclosed which consists of a container and a key part. The container should be sealed with a single-layer label.

In the WO 93/17933 A Also, there is disclosed a container for holding wet wipes, which are in turn in an airtight bag. The bag is stored in the container. Furthermore, the bag is reversibly closed with a single-layer label.

The WO 2006/092447 A1 discloses a label from a base label,

• - whose underside is equipped with a first adhesive layer, which is optionally covered with a release paper or a release film until the label is glued,
• In which a cutout is provided whose connection with the rest of the basic label is weakened or severed,

and with a cover label,

• - The underside is equipped with a second adhesive layer, by means of the

cover label glued on the basic label, taking the bond strength of the basic label higher on the base where the label is glued as the bond strength of the cover label is on the base label as well the bond strength between neckline and cover label is higher is considered the force that is required, the lid in the package by means of the glued portion of the packaging separate.

simultaneously is this adhesive force higher than the force that leads to Separating the clipping from the ground to which the label is glued is required.

Possibly On the cover label further protective labels are provided which For example, in Leporellofaltung further information included can

Of Furthermore, there are packaging, for example for cheese slices or pieces of cheese, consisting of a two-sided sealed plastic tube bag.

Such tubular bag packaging are known in particular for the packaging of processed cheese. Here are usually several melted cheese slices, which are each welded separately into a plastic bag included. These known plastic tube bags are usually formed by flat films that they form a seal line in a corresponding flow wrapper on one side. These existing plastic bag packaging can be torn, for example, in the region of this central plastic seam. Alternatively, a corresponding elevation be provided in the region of the lateral sealing seams. All known plastic tube bag packaging for melted cheese slices, it is now common that they can not be resealed after opening. As a result, cheese slices which have not been removed can easily fall out of the packaging during storage in the refrigerator, so that the function of the outer packaging can no longer be fulfilled.

to Packaging of cheese slices or pieces of cheese On the other hand, plastic cups are already known that made thermoformed plastic trays in which the cheese is placed. These plastic trays are closed with plastic films, which are usually sealed at the edge of the shell with this. Re-closure systems are already in the field of these packaging known. For this purpose is in the closing foil a self-adhesive pressure sensitive adhesive installed by the corresponding Pressing the film on the flange edge a resealing Packaging possible.

According to the DE 102 32 959 A1 is in a package for cheese slices or pieces of cheese consisting of a two-sided sealed plastic tube bag on one side over almost the entire length of the plastic bag bag a line that traces a tab contour stamped. The packaging is pasted over in the area of this line with a self-adhesive, single-layer adhesive label. As a result, the soft plastic tube bag package can be opened by pulling on the self-adhesive adhesive label along the pre-punched flap contour, so that here the individual cheese slices or the piece of cheese can be removed. After removal of the desired cheese slice or after covering the unused cheese piece, the tubular bag packaging can be resealed by folding the tab and re-bonding means of the self-adhesive adhesive label.

The stamped line is pasted over in particular by means of a transparent label. The transparent label has a red colored grip tab, which serves for tearing open the transparent label. In two Corner areas are provided in the transparent label stampings, which form a predetermined tear line. After opening becomes the clear label along the predetermined tear lines torn. This makes it obvious to the user that the Packaging has already been opened. The transparent label is coated with a pressure-sensitive adhesive.

such Packaging can also be opened by the sealing seam is torn open, with the help of scissors or a Tear thread.

task The present invention is to provide a label that easy to open, yet safe on the ground, in particular a package for cheese slices or cheese pieces consisting of a two-sided sealed plastic tube bag glued and a reseal the packaging allows.

Solved This task is explained by a label as stated in the main claim is. Subject of the dependent claims are advantageous developments of The subject matter. Furthermore, the invention relates to proposed uses the label of the invention.

• – das auf der flexiblen Verpackung verklebt werden kann,
• – dessen Unterseite mit einer ersten Klebeschicht ausgerüstet ist, die gegebenenfalls vor der Verklebung des Etiketts mit einem Trennpapier oder einer Trennfolie abgedeckt ist,
• – in dem eine auftrennbare Schwächungslinie vorgesehen ist, die das Grundetikett in einen vorderen und einen hinteren Bereich teilt,

Accordingly, the invention relates to an at least two-layered label, in particular for tearing and reclosing of flexible packaging, with a base label,

• - which can be glued on the flexible packaging,
• The underside of which is provided with a first adhesive layer which, if appropriate, is covered with a release paper or release film before the label is adhesively bonded,
• In which a separable line of weakness is provided, which divides the base label into a front and a back area,

• – dessen Unterseite mit einer zweiten, Klebeschicht ausgerüstet ist, mittels der das Decketikett auf dem Grundetikett verklebt ist,

wobei die Klebkraft zwischen Decketikett und dem vorderen Bereich des Grundetiketts geringer ist als die Klebkraft zwischen Grundetikett und der flexiblen Verpackung und wobei die Klebkraft zwischen Decketikett und dem vorderen Bereich des Grundetiketts so eingestellt ist, dass Decketikett und vordere Bereich des Grundetiketts beschädigungslos voneinander getrennt werden können,
wobei die Klebkraft zwischen Decketikett und dem hinteren Bereich des Grundetiketts höher ist als die Kraft, die zum Auftrennen der Schwächungslinie erforderlich ist,
sowie gegebenenfalls mit auf dem Decketikett vorgesehenen weiteren Schutzetiketten, die beispielsweise in Leporellofaltung weitere Informationen enthalten können.and with a cover label,

• The underside of which is provided with a second adhesive layer by means of which the cover label is glued to the base label,

wherein the bond strength between the cover label and the front portion of the base label is less than the bond strength between the base label and the flexible package and wherein the bond between the cover label and the front portion of the base label is adjusted so that the cover label and front portion of the base label can be separated from each other without damage .
wherein the bond strength between the cover label and the back portion of the base label is higher than the force required to sever the line of weakness,
and optionally with further protective labels provided on the cover label, which may contain further information, for example in Leporellofaltung.

In Another preferred embodiment is the cover label and the basic label congruent and are also glued together congruent.

Further Preferably, the label is substantially rectangular, where appropriate the corners are rounded.

The Line of weakness preferably separates the base label into two approximately equal halves.

The Adhesion between the cover label and the front area of the basic label can be reduced by the fact that the adhesive is in the range of Cover labels covering the front of the basic label, partially inactivated (for example by irradiation, powdering or partial neutralization) or the adhesive is applied only partially is.

It But be sure to set a sufficiently high bond strength is to unintentional release of the cover label too prevent.

The different bond strengths of the cover label to the front or back of the basic label can also through the use of two different adhesives within the second adhesive layer can be achieved. For this purpose, a removable, low tack adhesives are used in the area in which the cover label should be removed from the basic label (when opening the packaging). In the rear area, however, is a higher Bonding adhesive used to prevent the unwanted To prevent detachment of the cover label.

Further the surface of the base label may be abhesive in the front area be.

The abhesive base label preferably by siliconization, for example in a silicone release lacquer is printed on the appropriate places. Another possibility is to create an abhesive effect Paint or primer to apply.

So then the surface of the basic label can be irradiated or chemical treatment such as etching changes be so that sets a Abhäsive effect. At the abhesive areas is the detachment of the cover label from the basic label during the opening process of the label.

By the reduction of the bond strength between the front area of the Basic labels and the cover label can be the cover label just peel it off to the back of the basic label, which is not adhesive-reduced connected to the cover label. In this area is the bond between cover and base label so large that a separation only possible by force is.

Of Further, the cover label after removal of a piece from the packaging reversibly applied to the basic label reversible The residual adhesion keeps the cover label repeated in position.

In a further preferred embodiment of the invention is in the area of the cover label that covers the front of the Basic label covers, an area in the edge area adhesive-free, is the bond strength of this area is reduced or is the adhesive is covered in the area of this area. This area then serves as a handle for removing the cover label.

A Another way to make a handle is in it, the adhesive forming the surface by a release paper cover so that the adhesive can have no effect. Of Furthermore, the adhesive in this area can also be neutralized be, for example, by printing or powdering.

In In one variant, the handle is formed by attaching to the cover label provided an additional area.

This Handle is preferably arranged so that it is at one edge lying opposite the back of the basic label.

Next The handle in the cover label can also have a handle in the basic label be present, preferably the handle in the cover label and the handle on the base label stacked and especially the same size.

This Handles can match the construction of the handle in cover label, which is also the preferred embodiment.

The Label is preferably on flexible packaging such as tubular bags, where foods such as cheese slices or cheese pieces are used.

In the tubular bag is advantageously by punching a second line of weakness exists, carried out in such a way is that the tubular bag further closed air and water tight is. This weakening line can be used to open the Tubular bag easily be severed, leaving a flap results, which can be opened and closed. From the resulting opening, can the contents, such as the cheese slices, removed become.

Far This kind of packaging is widespread, for example, in the case of paper handkerchiefs.

Prefers essentially shows the line of weakness of the tubular bag the same shape as the weakening line of the label.

The Inventive label is on the package glued by first the possibly existing Release paper is removed from the first adhesive coating and then the label or the base label by means of the first adhesive coating firmly adhered to the packaging.

The Label or the base label is preferably glued so that the present in the basic label line of weakness as possible congruent on the weakening line in the tubular bag rests.

During the opening process the label separates the cover label from the front of the label Basic labels until the line of weakness is reached. Becomes pulled further on the cover label, breaks due to the strong bond between the cover label and the back of the basic label the Line of weakness.

At the Continued pulling settles from the line of weakness outgoing crack in the basic label continues until the edges of the basic label be reached and the back area of the basic label completely separates from the front area.

simultaneously with severing the line of weakness in the cover label also ruptures the packaging, which is why preferably below the weakening line of the label a second Has weakening line. The second line of weakness splits simultaneously with the weakening line in the label. With the further opening of the label also breaks the packaging on, it forms a tab.

Prefers Therefore, a line is provided in the packaging, which is the contour a tab, wherein the second weakening line a part of this line is. Because of this line is the consumptive power very low, making it easy to open the label forming the tab.

is the label fully opened, the front sticks Area of the basic label on the packaging, directly before the point where the tab starts, during the rear area of the label with the cover label on the resulting Tab sticks.

by virtue of The irreversible separation of the label is a security aspect realized. The first opening of the packaging will clearly indicated to the consumer.

The Weakening lines as well as the line can be punched or precut, for example in the form of a perforation.

The Line of weakness in the base label extends according to one advantageous embodiment of the invention over the entire width of the label (starting at one edge of the label and extending to the opposite edge) and is further preferably substantially straight and parallel to the front Edge of the label arranged. To the edges of the label can weaken the line in a slightly curved Form, for example in an S-form, leak.

Preferably accordingly has the line of weakness in the tubular bag this shape up.

The Top and bottom of the cover label can be printed but they do not have to. The basic label can also be printed be.

To the Closing the packaging, the flap is folded back, until the two parts of the label lie on top of each other again and stick together.

The Advantages of the label according to the invention in particular in preferred embodiments are shown as follows.

The Label is easy to open, as it is not from the packaging film), but the cover label from the basic label.

Yet a secure bond on the packaging is guaranteed by the basic label.

Of Further, there are three pages (top and bottom of the cover label as well as top of the basic label) printable, that is, rather, information is available than before.

When Support materials of the cover or base label stand Papers or different slides to choose from.

According to the invention as Materials can be used films, especially monoaxial and biaxially oriented films based on polyolefins, then films based on stretched polyethylene or stretched copolymers, containing ethylene and / or polypropylene units, optionally also PVC films, PET films, films based on vinyl polymers, Polyamides, polyesters, polyacetals, polycarbonates Also films based on stretched polyethylene or stretched copolymers, containing ethylene and / or polypropylene units, can be use according to the invention.

Monoaxially stretched polypropylene is characterized by its very high tensile strength and low elongation in the longitudinal direction. Preferred for Production of the labels according to the invention are monoaxially stretched films based on polypropylene. The thicknesses of the monoaxially stretched films based on polypropylene are preferably between 20 and 100 μm, in particular between 25 and 65 μm, very particularly between 30 and 60 μm.

uniaxially stretched films are predominantly single-layered, basically but can also be multilayer monoaxially stretched films getting produced. Mostly one-, two- and three-layer films, wherein the number of layers also larger can be chosen.

The Thicknesses of the biaxially oriented films are based on polypropylene especially between 12 and 100 μm, especially between 20 and 75 μm, especially between 30 and 60 μm.

biaxially stretched films based on polypropylene can by means of Blown film extrusion or by means of conventional flat film systems getting produced. Biaxially stretched films are both as- also produced in several layers. In the case of multilayer films Here too, the thickness and composition of the various can Layers be the same but also different thicknesses and compositions are known.

Especially preferred for the labels according to the invention are single-layer, biaxially or monoaxially stretched films and multilayer, biaxial or monoaxial films based on polypropylene, the have a sufficiently strong bond between the layers, because delamination of the layers during use is disadvantageous.

films based on rigid PVC are used for the production of labels as well used like films based on soft PVC.

For the labels according to the invention then become customary Foils used based on rigid PVC. The thicknesses of the films are preferably between 20 and 100 μm, especially between 25 and 65 microns, especially between 30 and 60 microns.

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

Prefers the films used are transparent, preferably speaking a transmission of greater than 60%, in particular a transmission greater than 90% at one wavelength from 350 to 1150 nm.

With the transmittance - sometimes only briefly as transmission is denoted - usually in% the ratio of on the back of a with Light irradiated the body's incoming light output meant to the incident on the front light output. The transmission is trimmed by reflection and absorption.

It therefore applies: Transmittance = (1 - reflectance) × (1 - absorbance).

The Inventive labels can as Adhesive an adhesive based on natural rubber, PUR, acrylates or styrene-isoprene-styrene block copolymers.

The use of adhesives based on natural rubber, acrylates or styrene-isoprene-styrene is known, which is also known, for example, in US Pat. Handbook of Pressure sensitive adhesive technology, second edition, edited by Donatas Satas, Van Nostrand Reinhold, New York, 1989 is described.

When Self-adhesive mass comes in particular a commercial one pressure-sensitive adhesive based on PUR, acrylate or rubber for use.

Based the figures described below is a label in one explained particularly advantageous embodiment, without unnecessarily restricting the invention to want.

It demonstrate

1 the label, in plan view, with all layers being transparent,

2 the label according to 1 before putting it on a tubular bag 7 is glued,

3 the label according to 1 after putting it on a tubular bag 7 is glued,

4 the label in another embodiment in plan view and

5 the split label according to 4 after the separation.

According to 1 is the label 1 from a basic label 3 whose bottom is covered with a first adhesive layer 5 equipped. This can with a release paper, not shown here or a Be covered release film. By means of the adhesive layer 5 the label is glued to the substrate, so a package.

In the basic label 3 is a severable weakening line 33 provided the basic label 3 in a front area 31 and a rear area 32 Splits. The line of weakness 33 extends over the entire width of the label 1 and is largely straight and parallel to the leading edge of the label 1 arranged. To the edges of the label runs the line of weakness 33 each in an S-shape.

The top of the front area 31 is abhesively equipped with a silicone coating.

Furthermore, there is the label 1 from a cover label 2 whose underside has a second adhesive layer 5 equipped, by means of the cover label 2 on the basic label 3 is glued. The area of the cover label 2 is congruent to the area of the basic label 3 executed.

Cover and base label 2 . 3 are rectangular here.

It is essential to the invention that the bond strength between cover label 2 and the front area 31 of the basic label 3 less than the bond between base label 3 and the flexible packaging 7 on the label 1 is glued, and that the bond between cover label 2 and the front of the basic label 3 is set so that cover label 2 and front area 31 of the basic label 3 can be separated from each other without damage.

This adhesive force reduction results from the fact that, as described above, the top of the front region 31 of the basic label 3 Abhesively equipped, resulting in a reduced adhesion of the adhesive 4 on the basic label 3 leads.

The bond between cover label 2 and the rear area 32 of the basic label 3 is then higher than the force needed to sever the line of weakness 33 is required.

Both cover label 2 as well as basic label 3 each have a grip area 24 . 34 on. The handles 24 . 34 consist of a non-adhesive coated film section of the films, the cover label 2 and the basic label 3 form.

The handles 24 . 34 can be used to split the label 1 each between thumb and forefinger are taken. These are then pulled apart, which causes the slight bond between the cover label 2 and the front area 31 rises.

According to the 2 and 3 becomes the label 1 using the first adhesive coating 5 on the basic label 3 in particular to a tubular bag 7 glued on, in the tubular bag 7 a tab area 71 through punched lines 72 is pre-punched. In the tube bag 7 is a second line of weakness 73 which has the same shape as the weakening line 33 in the basic label 3 ,

In the 2 is the label 1 according to 1 shown before it on the tubular bag 7 is glued. In the 3 is the label 1 according to 1 shown after it on the tubular bag 7 is glued. The label is glued so that the two lines of weakness 33 . 73 as congruent as possible.

The filled with content and with the label 1 provided tubular bag 7 can now be sold and can be purchased by a customer.

In the tubular bag 4 For example, there are pieces of cheese or cheese slices.

When opening the label 1 , which is initiated by the customer, separates the cover label 2 from the front area 31 of the basic label 3 until the line of weakness 33 is reached. Continue on the cover label 2 pulled, breaking due to the strong bonding between cover label 2 and rear area 32 of the basic label 3 the line of weakness 33 on.

Would the line of weakness 33 not over the entire width of the label 1 extend, the continued pulling would be from the line of weakness 33 outgoing crack in the basic label 3 Continue until the edges of the basic label 3 be reached and the rear area 32 of the basic label 3 completely from the front area 31 separates.

In the illustrated embodiment, the line of weakness cuts through 33 immediately the label 1 ,

Simultaneously with the breaking of the weakening line 33 in the cover label 2 also tears the packaging 7 on that below the line of weakness 33 of the label 1 a second line of weakness 73 having. The second line of weakness 73 splits simultaneously with the one in the label 1 located weakening line 33 , With the further opening of the label 1 also tears open the packaging on, it forms a tab 71 by putting in the tubular bag 7 provided punching lines 72 , which together with the weakening line a tab area 71 have ripped open.

Is the label 1 completely open, the front area sticks 31 of the basic label 3 on the packaging 7 , and just before the point where the tab 71 starts while the back area 32 of the label 1 with the cover label 2 on the resulting tab 71 sticks.

In the 4 is the not yet separated label 1 in another embodiment shown in plan view. The label 1 has a rectangular shape, with the corners are rounded.

On the cover label 2 is a grip area 24 intended.

Because both cover label 2 and basic label 3 consist of transparent films, is the line of weakness 33 to recognize the basic label 3 in a front area 31 and a rear area 32 separates.

5 puts the split label 1 according to the 4 after the separation. On the tubular bag 7 only the front area remains 31 of the basic label, while the back area 34 of the basic label 3 along with the cover label 2 on the in the tubular bag 7 resulting tab 71 is glued.
