Definitions

• the invention relates to paper, aluminum, plastic films or compositions thereof, mechanically removable labels for identifying tradable objects according to the preamble of the claim.
• Such labels are known from DE-OS 37 34 640. There, too, the back of the detachable label is acted upon by at least one substance causing the adhesion, which has a detachable first substance which can be worked into the label material and a second substance which is compared to a glass bottle or the like. Object identified by the label should have adhesion promoter properties.
• the first substance contains a solid content between 20 and 80% as a sweat-proof separating layer substance and has a processing viscosity, measured in a Frickma flow cup, of 25 to 40 seconds.
• the labels described there are preferably used in the beverage industry, for example on beer bottles, where they have to meet particularly high requirements. These affect both their processing or application speed, at which up to 65,000 bottles per hour have to be filled and labeled, and their storage stability under extreme weather conditions, such as strong temperature fluctuations, moisture influences and the like. more.
• the labels of interest here are applied to objects, such as beer bottles, characterized by special problems, in particular the cleaning of the returned goods also poses considerable difficulties. So far, the labels have been washed off using heated washing water with a high water throughput.
• the handling of the dirt load of the wastewater is correspondingly complex, whereby it is not only about the required cellulose-fiber-free filtration of this wastewater, but in particular also about the removal of metal components, in particular aluminum compounds, from the wastewater, which are increased to a greater extent by the printing, i.e. the color components of the Labels, are present.
• the labels are removed in the bottle cleaning machine in a 2.5% NaOH solution at an average temperature of 82 oC .
• a bottle neck film is known from DE-OS 31 37 324 an aluminum foil section coated on both sides with a protective layer, the protective layer consisting of a mixture of 1 to 40% alkali-resistant and 60 to 99% alkali-resistant binders.
• Polyvinyl acetate, polyamide resins, melamine resins or cellulose nitrate are used as alkali-resistant binders.
• the alkali-resistant binders specified are polyester resins made from terephthalic acid and aliphatic diols, vinyl chloride copolymers, polyvinyl butyral resins, acrylic resins or methacrylic resins or mixtures thereof.
• the alkali-resistant coating has the advantage that it or the like is relatively easy from the bottle.
• Object dissolves so that the actual washing-off process of the label can either be accelerated or carried out with lower washing solution volumes.
• Both alkali-resistant and alkali-resistant binders are used here exclusively to prevent excessively long dwell times in the wash liquor even when the system is down.
• Belly labels as well as back and chest labels can be known to contain a high proportion of aluminum.
• the neck foils consist largely of aluminum foil.
• the mostly multicolored printing of the labels increasingly uses gold- or silver-metal-colored components, which results in increased concentrations of preferably aluminates in the cleaning solution.
• the aluminate is an aluminum sludge that settles down in the washing machine and is disposed of. The hydrogen is sucked upwards out of the cleaning machine.
• the alkali-resistant coating tries to contrast the aluminum foil To keep the alkali resistant and, if possible, to remove the neck foil from the alkali like a paper without the aluminum having dissolved in the alkali.
• special preparation properties of the back of the labels are essential for such a dry disposal in bottle cleaning.
• the preparation properties and the interacting design of the back of the label must be such that first of all the detachment of the return labels from the objects is to be ensured as far as possible in the mechanical drying process, only then and then can wet cleaning be used to prepare the return empties for a new filling process.
• the object on which the present invention is based is to make a particularly suitable choice of substance for the layer or solvent in which the substance of the first layer is present.
• the labels thus formed can be dry Use a suitable washing machine to remove the condition from your object with almost no residue using a water jet or air jet, so that the subsequent liquid cleaning of the items freed from the labels can only be limited to cleaning the surface of the glass bottle inside and outside.
• the washing solution carries no or only very little dirt with label residues, which considerably eases the associated environmental problems.
• the previously usual lye concentrations can be reduced considerably, which also applies to the washing temperature of the return bottles already cleaned by the detergents.
• the non-entry of the specially coated labels and foils into the lye makes it possible to reduce the up to 4% high NaOH lye to approx. 1 to 1.5%. Furthermore, the carryover of lye by the labels is eliminated, which means an additional saving of NaOH and energy.
• the inner or first layer to be incorporated into the label material must consist of a substance which must be dispersed in solvent or water or in dissolved form, the solvents being alcohols, the carbon valences of which are at the carbon atoms C1 to C5 .
• the solvents being alcohols, the carbon valences of which are at the carbon atoms C1 to C5 .
• Various esters of alcohols from C1 to C4 and carboxylic acids from C2 to C4 have also proven to be quite advantageous.
• the synthetic binders selected for the first backside coating are those based on ketone resin, polyester, polyacrylate, polyamide, polyurethane and / or natural binders based on rosin or shellac. Dispersions are produced with the addition of paraffin with a melting range of 25 to 150 o C. Only substances composed in this way for the first layer result in a sweat-proof separation, which is important both for the application of the label to an object to be identified with it and for the commercial handling of such Objects up to consumption and finally for the separation in the recycling process show advantages that were previously not accessible to the professional world.
• the above-mentioned selection of substances ensures that the label is detached from its object mechanically independent of temperature, as well as good adhesion between the label and the adhesive layer or glue layer as the coating material for the object to be labeled.
• the latest, stricter environmental requirements are fully taken into account, thereby contributing to the dual waste management system. If the labels do not enter the lye, the previously removed neck foils can be sent for direct recycling to restore neck foils, since there is no loss of quality with aluminum and the paper labels can also be disposed of in the recycling system.
• the surface of the label must be such that the label cannot be moistened from the outside. This is achieved through a paper quality specially produced for this system and, if necessary, through additional finishing in the form of a special one Painting. If this were not the case, the labels in the wet bottle cellar would wet very easily, and at the moment of spraying the water jet would not separate the labels from the glue pattern, but the paper would be separated or frayed.
• the sweat water coming from the bottle has to be carried out through the label so that the glue sets at all and undergoes a drying process.
• the labels must also be such that they behave as equivalent to normal labels, i.e. normal alkali penetration and detachment must also be ensured in the bottle washer.
• the lye must not be stronger than with the normal, i.e. be burdened with the previously known labels.
• the weather process is very important. Due to the different temperatures, new condensation water is always created even when taking a cold bottle out of the fridge. Despite the repeated occurrence of condensation water processes, the water must penetrate through the label from the back to the front so that the drying process takes place again, but the glue must not pass through the release component.
