Definitions

  • the invention relates to a transfer label, with a carrier material layer, one detachable on the carrier material layer arranged, attachable to an object by means of adhesive Imprint layer and one between the carrier material layer and the print layer arranged from the Carrier material layer removable protective layer.
  • a label of this type is known from W090 / 05088.
  • a high gloss coated substrate and a layer of release material for the layers to be transferred to the substrate provided which in the transfer of the Labels on the item are activated by heat in this way is that they detach the layers to be transferred from the carrier material. If this separating material layer is missing, the carrier material can not be from the still heated Peel off the label.
  • an additional protective layer is applied to the object, and then it is hardened under UV radiation. This post-curing process takes a relatively long time Running distance and is mechanically complex. This is especially true if the items are beverage glass bottles acts to reduce friction in crowded areas of bottle filling systems covered with a plastic layer which are to be spared with UV radiation.
  • a transfer label is known from US Pat. No. 4,529,624 Outer layer over a meltable during transmission Paraffin layer is connected to the carrier material. The Paraffin layer remains on the label after transfer, residues may remain on the carrier. The transfer is therefore not always complete.
  • the paraffin layer is smoothed by subsequent flame treatment and therefore more transparent and shiny and less visible.
  • the object of the invention is therefore to provide a transfer label, that can be transferred without residue to an object is and does not require after-treatment.
  • the parting line between carrier material and protective film is special precisely defined, so that the label is targeted from the carrier material peel off and apply smoothly.
  • the interaction the adjoining surfaces of protective film and Backing material is based on adhesive forces, such as electrostatic Powers. After separating the label from the Backing material and transfer to the object now remains the exposed surface of the protective film is independent of temperature not adhesive.
  • the protective film is hard and scratch-resistant.
  • the carrier material layer and the protective film preferably form a material pairing with essentially temperature-independent predetermined holding force.
  • the carrier material layer can be made of consist of several sub-layers.
  • the carrier material layer is preferably present at least on the one facing the protective film Polypropylene side, the protective film Side is preferably untreated.
  • the thickness of the substrate can be 20 to 100 microns, preferably 35 to 60 microns. So that the combination of carrier material layer and transfer labels can easily unwind from a roll, the side of the carrier material layer that repels the protective film have a non-stick finish, such as siliconized or Separating varnish.
  • the protective film is preferably made of radiation curing Lacquer, especially cationically cold-crosslinked, under ultraviolet light curing lacquer formed. Cold-curing Cationic UV varnish hardens under UV radiation out. The chain reaction begins with UV light. The networking and curing takes place completely without further UV exposure. The protective film remains after curing non-sticky.
  • An electron beam hardener is also an option Paint.
  • the paint used should be heat stable so that it is Properties under the influence of heat application in the Transmission does not change.
  • the protective film consists of non-sticky paints.
  • the protective film is thinner than the carrier material layer, preferred by a factor of 2 to a factor of 100, particularly preferred 10 to 20.
  • the protective film is preferably 1 to 10 ⁇ m thick, particularly preferably 2.5 to 5 ⁇ m. The thinner the protective film the lower the label transfer required Thermal energy and the lower the thermal load of the object. This is of particular concern, though the object is a slide with plastic coated beverage glass bottle.
  • the Protective film can be stretched, with an elongation at break in the range of about 50-400%, preferably about 100-300%, preferred 150-250%, preferably about 200%.
  • a PE or PP protective layer also comes in as a protective film Question (polyethylene or polypropylene), which by adhesion does not adhere to the substrate layer.
  • the Protective film can be co-extruded with the backing material layer his.
  • the print layers can be made from solvent-based lacquers consist. They are preferably water-insoluble, heat-resistant, colourfast, tonal stable, opaque and heat stable.
  • the print layer and Protective film it can happen that the print layers only adhere poorly directly to the protective film, for example if it contains solvents Layers on a cationically UV-cured Protective film should be printed. Recommended in these cases a suitable one before printing on the printing layers Print the primer layer on the protective film.
  • the primer layer acts as an adhesion promoter.
  • the primer layer can be single-layer and have non-adhesive properties also as a barrier against immigration from solvents the print layer act in the protective film.
  • the primer layer can have a protective film-side adhesive layer and on top have an additional barrier layer, or from the protective film starting an adhesive layer, a barrier layer and another adhesive layer, on which the printed layers are then placed to be printed.
  • the elasticity of the print layer and possibly the primer layer, the barrier layer and the adhesive layer (s) can be adapted to that of the protective film, the extensibility of the individual layers from the adhesive side to the protective film side can decrease. This allows damage-free Transfer the label to the item at the same time high protective effect of the protective film.
  • the adhesive layer can consist of a pressure sensitive adhesive, a first After a single heat exposure, permanently adhesive thermo-activatable Glue or just sticky during heating thermosensitive adhesive can be formed.
  • thermo-activatable adhesive can be a two-component adhesive be a component or a reactant is in microcapsules that are exposed to heat burst and then a mixture of the two components and this causes a curing reaction.
  • the usage such two-component adhesives when gluing of labels on objects is independent of the construction of the label.
  • the object When sticking the label on the object should use a thermally activated adhesive is the object be preheated as precisely as possible to that temperature at which is to be warmed up during application.
  • the Temperature should be in a range where a friction-reducing Plastic coating of a label Glass bottle is not damaged.
  • the label is produced by printing on the respective one Layers in succession on the carrier material layer, wherein the protective film and the print or color layers and if necessary the primer is essentially the same shape on the substrate layer be printed on.
  • the protective film can protect the edges of the color layers overlap them.
  • the adhesive layer also has the same contour as the layers of paint and printed on the protective film.
  • a carrier material 1 the multi-layer of coextruded Polypropylene or polyethylene on a paper backing can be formed and have a thickness of 20 to 100 microns has a low-adhesion surface 1a of the polypropylene with low surface energy. With coextrusion several thermoplastic materials are common extruded. The result is multilayer films that face each other simple foils have the advantage that the individual Layers can have different functions (e.g. smooth outer layer for good printing or inner layers with adhesive surface for low blocking effect).
  • the polypropylene or polyethylene is untreated so that it has a low surface energy or surface tension from e.g. 28-32 mN / m.

  • the adhesive effect is independent of temperature.
  • the protective film 3 consists preferably of cationically cold-crosslinking, under UV radiation curing varnish, which is a chain reaction due to UV light starts and cures completely and after curing remains non-sticky.
