Definitions

  • the invention relates to a label for sticking on a vessel, in particular on an ice cream container, preferably on an ice cream bowl, made of polystyrene.
  • the object of the invention is to provide a label of this type which can also be reprocessed without difficulty during the reprocessing (recycling) of the polystyrene container.
  • the label is characterized by a label film made of polystyrene provided on the underside with a pressure-sensitive adhesive layer and a cover film made of transparent polystyrene glued on by means of a laminating adhesive layer, through which a pressure is visible.
  • a particularly heat-insulating label is obtained if an intermediate film made of polystyrene is glued onto the label film by means of a laminating adhesive layer and the cover film is glued onto this intermediate film.
  • the pressure is preferably applied to one side, in particular the upper side, of the intermediate film.
  • the label is preferably characterized in that the label film is extruded flat, is biaxially stretched, has an elongation at break in the longitudinal direction of at least 5% according to ASTM-D 882, has an elongation at break in the transverse direction of at least 45% according to ASTM-D 882, and has a tensile strength of at least 60 N / mm2 according to ASTM-D 882, has a density of 1.05 to 1.15 g / cm3, preferably 1.11 to 1.13 g / cm3, and a thickness of 50 to 70 ⁇ m, preferred 62 to 66 microns.
  • a label with Such a label film is particularly easy to manufacture and process.
  • the label is preferably characterized in that the surface tension of that side of the film to which the pressure is applied, preferably by corona treatment, is increased to at least 46 mN / m.
  • the label is preferably characterized in that the surface tension of that side of the film to which an adhesive is applied, preferably by corona treatment, is increased to at least 36 mN / m.
  • the label is preferably characterized in that the cover film has a transparency of at least 90% according to ASTM-D 103.
  • the cover film can also be matt or glossy.
  • the cover film and / or the intermediate film during shock freezing - for about 1 hour to -36 ° C - is special dimensionally stable, if it is biaxially stretched, has an elongation at break in the longitudinal and transverse directions of 1 to 5% according to ASTM-D 882, a density of 1.05 to 1.15 g / m3, preferably 1.11 to 1.13 g / cm3, and has a thickness of 15 to 40 microns, preferably 22 to 28 microns.
  • the respective laminating adhesive layer preferably consists of a - preferably highly transparent, preferably soluble in ethyl alcohol - two-component adhesive on a polyurethane basis with an applied weight in the dry state of 1 to 3 g / m2, preferably 1.8 to 2.2 g / m2, and a peel strength of at least 1 N / 15 mm according to FINAT FTM 1.
  • a special property of such a lamination adhesive layer is that it is still elastic even at low temperatures.
  • the pressure-sensitive adhesive layer also tolerates low temperatures and is particularly adhesive in a range from -40 ° to + 80 ° C
  • the pressure-sensitive adhesive layer preferably consists of an aqueous dispersed adhesive based on acrylate with an application weight of 15 to 25 g / m2, preferably 18 to 22 g / m2.
  • the label is preferably characterized in that the print is formed by a thermoplastic printing ink, which is preferably soluble in ethyl acetate. Ethyl acetate slightly dissolves the polystyrene films, which improves the adhesion of the print.
  • the thermoplasticity of the printing ink makes it easier to reprocess the label, which would not be the case if it were a thermosetting printing ink.
  • a label with particularly high thermal insulation properties is characterized in that the label film consists of foamed polystyrene, preferably coextruded in two layers, with a thickness of 100 to 200 ⁇ m, preferably 140 to 160 ⁇ m. Due to the low hardness of the foamed polystyrene film, a foamed polystyrene film is difficult to print on. For this reason, the printing is preferably carried out on an intermediate film which is laminated onto the foamed polystyrene film. Such an intermediate film also makes it easier to punch the label and remove a leadframe, because the The tensile strength of a foamed polystyrene film is low.
  • the label is preferably applied to the polystyrene vessel immediately after its manufacture, that is, in a state in which the polystyrene of the vessel still releases gas.
  • the label is preferably characterized in that, overall and accordingly its layers, it has a gas permeability of more than 25 cm3 / 100 cm2 according to ASTM-D 1434.
  • the label with its pressure-sensitive adhesive layer is on a silicone layer which is applied to one side of a carrier made of kraft paper, the basis weight of which is 60 to 90 g / m 2, preferably 65 to 70 g / m 2, before being glued onto the vessel , is.
  • FIG. 1 there is a pressure-sensitive adhesive layer 4 on the underside of a label film 2.
  • the pressure-sensitive adhesive layer 4 adheres peelable (removable) to a silicone layer 6 of a carrier 8.
  • a pressure 10 is applied to the top of the label film 2.
  • a cover film 14 is laminated onto the print 10 by means of a laminating adhesive layer 12.
  • a cover film 34 is applied by means of a lamination adhesive layer 32 to a print 30 with which the upper side of an intermediate film 36 is printed, which in turn adheres to the upper side of the label film 22 via a liner adhesive layer 38.
  • the label film 22 is formed from two layers 22a and 22b of coextruded, foamed polystyrene.
  • a label film 42 composed of two layers 42a, 42b of coextruded, foamed polystyrene by means of a pressure-sensitive adhesive layer 44 on a silicone layer 46 of a carrier 48.
  • a cover film 54 is glued onto the label film 42 by means of a laminating adhesive layer 52, on the latter At the bottom there is a pressure 50.
