Definitions

  • Multilayer materials and uses thereof
  • the present invention relates to self-rollable multilayer materials with a separating layer, uses of such materials and various articles produced using the same.
  • release layers are regularly provided with release layers, for which pressure-sensitive adhesive layers only a non-permanent, i.e. again easily and residue-free detachable liability.
  • the separating layer is usually a silicone layer, the silicone resin being applied in liquid form to produce the layer.
  • this so-called wet coating is technically demanding and is only mastered by manufacturers that specialize in it.
  • the silicone resin is relatively expensive.
  • polymerize thicker silicone layers only incomplete and tend to lose their dehasive properties over time.
  • Sufficiently thin layers with the required quality can only be produced with the known technology on certain, in particular sufficiently smooth surfaces.
  • Normal writing or printer paper with a basis weight of 80-100 g / cm 2 as used in the office area, is much too rough and absorbent, for example.
  • the silicone layer has a layer thickness of not less than 10 ⁇ m.
  • the present invention solves the problem, inter alia, of specifying how a sufficiently thin and time-stable separating layer can be applied to a practically any surface in a manner which is simple to control and inexpensive. According to the invention this is achieved by using a multilayer material according to claim 1.
  • Claim 3 relates to a carrier provided with such a multilayer material.
  • a form provided with a self-adhesive label is claimed, in which a piece of a multilayer material of the type according to the invention is glued to the front side of the form with its adhesive back and with a second layer of adhesive on this piece of multilayer material and a piece of one on top of it Label material are applied.
  • Patent claim 12 specifies a method for producing such a form, in which the second Pressure sensitive adhesive layer is applied as a hot melt or wet glue to the first separating layer of the multilayer material piece.
  • the claim 14 relates to a further form with an integrated, removable card, for the production of which a multilayer material according to the invention is also used.
  • claim 17 relates to a more specific multilayer material as such, which can also be used at least in part within the scope of the aforementioned objects.
  • the advantages of the invention are to be seen essentially in the fact that the use of the multilayer material according to the invention eliminates the technically difficult to master wet siliconization and replaces it with easy-to-master dry application of a completely prefabricated material that has already been provided with a separating layer.
  • endless paper webs in form production can run at least twice the production speeds of conventional wet siliconization.
  • the multilayer material according to the invention can be applied to practically any surface without restrictions due to its specific properties.
  • the multilayer material according to the invention comprises at least two layers more than a wet-applied silicone layer, its use does not generally result in a greater overall layer thickness, since the individual layers of the multilayer material can be made very thin.
  • the thickness of the separating layer can be made thinner by up to an order of magnitude than that of a wet one, for example applied directly to a paper surface, by suitable choice of the material of the carrier layer.
  • the thinner layer thickness of the separating layer 4 also results in greater long-term stability with regard to the dehasive properties of the separating layer.
  • both the support in the label area and the label material itself can advantageously be pre-printed on both sides.
  • the present invention achieves improvements in terms of economy, process control, flexibility with regard to the carrier as well as product design, quality and stability.
  • 1 shows a first embodiment of a multilayer material according to the invention in a first preferred use, the result of which is a form provided with a self-adhesive label; 2 shows a further development of this embodiment, in which the label can be used as a vignette;
  • FIG. 3 shows a second embodiment of a multilayer material according to the invention in a second preferred use, the result of which is a form provided with two self-adhesive labels;
  • Fig. 4 shows a further use of the multilayer material according to its first embodiment in the context of a form with an integrated, so-called folding or butterfly card.
  • a carrier which can be a single sheet of paper, but in particular an endless web of paper or still connected sheets of paper.
  • the carrier 1 can be printed on one or both sides, which is indicated by symbolically represented print jobs 2.
  • the carrier 1 should, for example, run in the direction of the arrow 3 and thereby pass the stations designated as a), b) and c).
  • In station a) is first a piece of a multi-layer material
  • the multilayer material 4 according to the invention glued to its upper surface and a print job 2 which may be present there, for which purpose the multilayer material 4 is provided with a first pressure-sensitive adhesive layer 5.
  • the multilayer material 4 is constructed here in three layers and includes the pressure-sensitive adhesive layer
  • a second pressure-sensitive adhesive layer 8 is applied to the surface of the first release layer 7.
  • a piece of label material 9 is finally applied to this second pressure-sensitive adhesive layer, which piece firmly bonds to the adhesive adhesive of the second pressure-sensitive adhesive layer 8 and forms a self-adhesive label 10 together with it.
  • the label material 9 can consist of paper and be pre-printed on one or both sides, which is also indicated again by symbolically applied print jobs. One of these print jobs is labeled 11.
  • the result is a form web or a single form sheet 1 with a self-adhesive label 10 placed on one side, which can be detached from it due to the dehasive properties of the first separating layer 7 of the multilayer material 4 and can be stuck on again at another point by means of the second pressure-sensitive adhesive layer 8. 1 shows the self-adhesive label 10 in the detached state from the first separating layer 7.
  • the print job 2 initially hidden by the self-adhesive label 10 is advantageously visible on the top of the carrier 1 when the label 10 is removed.
  • FIG. 2 shows a further development of the product from FIG. 1.
  • a full circumferential punching is additionally made from the back of the carrier 1 within the second pressure-sensitive adhesive layer 8 and preferably from all sides from its edge to the side Depth of the first separation layer 7 attached, which is illustrated by the arrows 12. If the self-adhesive label 10 'is then removed, the punched-out layers 1 of the carrier and 5-7 of the multilayer material 4 with the label 10' go along, as is shown in the left part of FIG. 2. Because of the edge 13 of the second adhesive layer 8, which preferably protrudes on all sides over these layers, the label 10 'can, however, still be glued to another location.
  • a print job 2 'possibly applied to the punched-out piece of the carrier is visible through the pane.

  • a hot melt adhesive is preferably used for the pressure sensitive adhesive of the second pressure sensitive adhesive layer 8 and this is applied in liquid form. This is preferably done in such a way that the area covered by the second pressure-sensitive adhesive layer 8 is somewhat smaller on all sides than the multi-layer material piece 4 and the label material piece 9. It is hereby achieved that the adhesive of the second pressure-sensitive adhesive layer 8 does not emerge over the edge of the label material and, if, for example, several sheets of the type of FIG. 1 are stacked on top of one another, can cause them to stick together.

Due to this setting, the multilayer material 14 of FIG. 3 can also be rolled up on itself.
  • FIG. 4 shows under a) a form 20 in sheet form or again in endless form with an integrated, removable card K. Parts K1 and K2 lying one above the other in the card K (FIG. 4d) are partially arranged next to one another in the form, by folding them open but can be glued together.
  • the card parts K1 and K2 mentioned are included in the form in two areas B1 and B2. Covering these areas B1 and B2, a piece of a carrier material 21 is glued on, which, viewed from the form 20, comprises a third pressure-sensitive adhesive layer 22 and a second carrier layer 23.

  • a separating layer can be applied dry and in a simple manner to practically any surface.
  • the separating layer on the surface of the multilayer material according to the invention also makes it almost indescribable. Usual inks or the like do not adhere to it.
  • This property could be used, for example, to seal a specific print or signature on a document by pasting it over with the multilayer material according to the invention and to secure it against subsequent change.
  • a suitable choice of the pressure sensitive adhesive could ensure that it is impossible to remove the multilayer material without destroying the base to be protected.
