Definitions

  • the invention relates to a plastic film which is provided on one of its two surfaces with a silicone layer.
  • Such films are usually used to cover self-adhesive coated films or papers.
  • the low adhesive forces of the silicone layer on the covered adhesive layer make it easy to remove the cover film before the adhesive film is used as intended.
  • the invention has for its object to design the plastic film so that it allows a perfect curing of the applied silicone layer without special precautions of the type described. This hardening is achieved, for example, when At all points on the coating, the release force values of equal to or less than 0.2 N / 15 mm, measured with Tesa 651 adhesive tape and stored for 2 hours at 40 ° C, must not be exceeded.
  • This object is achieved in that at least the other side of the plastic film facing away from the silicone layer has a surface roughness that extends over the entire surface.
  • This surface roughness results in a cushioning effect in the wound web, so that irregularities are largely eliminated and pressure points are avoided.
  • the surface roughness is generated by an embossing pattern with an embossing depth of 2 to 30 ⁇ m.
  • a further advantageous embodiment of the invention is that a layer with a mineral filling is provided at least on the side of the film facing away from the silicone layer.
  • This mineral filling also has a cushioning effect so that irregularities cannot lead to pressure points.
  • a foamed layer is provided at least on the side of the film facing away from the silicone layer.
  • a further advantageous aspect of the invention results in that for the user of the siliconized film, the backside matting or embossing of the non-siliconized side creates an optical aid for identifying the film sides.
  • Fig. 1 is a plastic film, which is provided on its top with a silicone layer 2. On its lower side facing away from the silicone layer, the plastic film is provided with an embossed pattern 3, which gives the plastic film a roughness.
  • This embossed pattern can have irregular structures, e.g. are generated by sandblasted rolls, or have regular structures such as those transferred to the film by etched or engraved rolls during film production.
  • a plastic film 11 is again provided with a silicone layer 2 on its upper side. On its lower side facing away from the silicone layer, the plastic film is provided with a layer 4 which has a mineral filling 5. This mineral filling also creates a rough surface that serves to avoid pressure points.
  • a foamed layer 6 is applied to a plastic film 21 on its lower side facing away from the silicone layer 2.
  • This foamed layer 6 also has a rough surface, which rests on the silicone layer 2 of the layer below.
