• the glue layer 2 is now designed in such a way that the card 10 can be removed from the form, but on the other hand it is held so firmly in the form 1 that it does not detach itself when it is used as intended.
• Printing is among other things as intended to understand the form e.g. in a computer printer (inkjet or laser printer) as well as its dispatch by post
• FIG. 3 shows the form from FIG. 2 with the card 10 removed.
• the card 10 removed here still has the self-adhesive layer 4 and the complete glue layer 3 on the back.
• the glue layer 3 has been detached from the backing layer 2 completely and without residue when the card 10 is removed by an adhesion break
• the glue layer 3 has the property that it is no longer sticky at least after it has been detached from the carrier layer 2.
• the card 10 is (in contrast to, for example, a conventional one Self-adhesive label) on the back and therefore not sticky as a whole
• the glue layer 3 is also formed on the back of the card so that it can be written on, for example, with a ballpoint pen or a felt-tip pen
• the glue layer 3 therefore additionally has the task of acting as a diffusion barrier with respect to the self-adhesive of the self-adhesive layer 4, and preferably over a certain period of time, such as b for example at least one year
• this can be achieved in particular via its layer thickness, wherein a layer thickness of 8-10 g / m 2 should usually be sufficient
• a suitable glue for the glue layer 3 is, for example, such as can be obtained from SICPA-Aarberg AG, CH-3270 Aarberg under the designation 62-SE-243-1012
• glue is functional in the context of the present invention and is not to be understood merely in the narrow sense of an adhesive. Adhesive effect is only effective as long as the aforementioned separation has not yet taken place the glue rather has the properties of a dry lacquer above a film layer.
• the back of the detached card 10 from FIG. 3 is "plastified" when using the specified glue and thereby protects the printing or information, if any, underneath, such as a signature, etc., from manipulation
• FIG. 4 shows the detached card 10 from FIG. 3 over any surface 12.
• the self-adhesive 2 has been partially exposed on the back of the detached card 10 by partially mechanically scraping off the layer of glue 3 (for example with a knife or only with a fingernail). which makes the card sticky in the exposed areas. It can be glued to the surface 12 by pressing. An application for this would be, for example, gluing the card 10 into an album, as is usually done with photos.
• the card 10 could with appropriate training and printing, it is also a kind of photo
• FIG. 5 shows a further exemplary embodiment of the applicability of the multilayer material 1 from FIG. 1 in the form of a form 9 with a detachable card placed on it.
• the multilayer material 1 is here cut directly to the size of the desired card and after removal of the covering material 5/6 with its self-adhesive layer 4 glued to form 9
• the card 10' here consists exclusively of the material of the carrier layer 2, which consequently forms the actual wear layer in this embodiment and not just one Auxiliary function has As in the example of FIGS. 2 and 3, however, the layers are also separated between the glue layer 3 and the carrier layer 2, from which the glue layer is detached without residue. In the present example, the two layers 2 and 3 therefore do not go with the card 10 'with, but remain on the form There they form a thin, practically non-bulky dry and not (more) sticky coating which may even be writable. As in the example in FIG.
• the glue layer 3 of the Allow the self-adhesive layer to be removed at least partially, in particular mechanically, so that another object (possibly the card 10 'again) could be stuck onto the form on the self-adhesive spots exposed thereby
• the carrier layer 2 as the material for the card 10 'can preferably consist of stronger paper (for example 150 g / m 2 , cardboard or a plastic, so that the card 10' is sufficient after it has been detached from the form Has inherent rigidity and is therefore simpler and more durable in use.
• a rather thinner material for the support layer in the example of FIGS. 2 and 3 for example a polyester film with a thickness of 30-50 ⁇ m or a paper material with a thickness of 80 - 120 g / m 2 is usually sufficient
• FIG. 7 shows an embodiment similar to FIG. 6 with a card 10 ′′ detached from a form 9, but a cohesion break occurred within the glue layer 3 when the card was detached. Accordingly, only part 3 1 of the glue layer 3 remains on the form 9 as Cover for the self-adhesive layer 2 back, while another part 3 2 adheres to the back of the card and goes with the card 10 ".
• This adhesive partial layer 3 2 protects the card and can also preferably be written on.
• the partial layer 3 1 remaining on the self-adhesive layer 2 must of course be thick enough be able to cover the self-adhesive effectively and permanently,
• a breakage of cohesion occurs within the glue layer 3 can be determined via the material and / or surface properties of the glue layer 3 and / or the carrier layer 2 and / or Controlling and adjusting their affinity for one another In any case, however, the adhesion between the glue layer 2 and the self-adhesive layer 3 and the latter, in particular on conventional paper surfaces, must be greater than the stated affinity or the internal stability of the glue layer 3
• FIG. 8 shows a further multilayer material 1, which again comprises a backing layer 2, a glue layer 3 and a self-adhesive layer 4.
• the backing layer 2 is here provided on the back with a release coating 5 (siliconization), which means that the material also has no cover for the self-adhesive layer 4 can be produced in an endless form and rolled up
• the glue layer 3 is shown in FIG. 8 with two sub-layers 3 3 and 3 4, which, however, are not identical to the abovementioned sub-layers 3 1 and 3 2.
• the glue layer 3 is already a two-layer structure, basically further layers could also be provided.
• the multilayer structure makes it possible in particular to optimize the glue layer 3 with regard to its various functionalities described above.
• the partial layer 3 4 could consist of a material which has particularly good barrier properties and prevents the self-adhesive of the layer 4 from doing so to diffuse through the glue layer 3 as a whole.
• the other sub-layer (s) 3 3 could be set and optimized independently with regard to the further properties such as detachability, loss of adhesion and, if applicable, writability.
