Definitions

  • the invention relates to a method for producing an oriented plastic film from polyolefins and / or combinations of polyolefins and polyamide, which are produced in the extrusion or coextrusion blow molding process.
  • the object of the invention is to improve this method even further.
  • This task is solved according to the invention in that a first biaxially stretching takes place during the blowing process, which is followed by a further stretching.
  • a further advantageous embodiment of the method according to the invention is that the second stretching takes place immediately after the first stretching.
  • thermoforming the blown film for stretching is set at 90 to 180 ° C. depending on the plastic material used for the production.
  • tempering rollers can be used to temper the film before the second stretching, which set the film temperature to approximately 100 to 180 ° C. If the film has already cooled down considerably, according to a further embodiment of the invention, the film can be heated to the desired stretching temperature of about 100 to 180 ° C. by means of heat radiators before the second stretching.
  • the film is annealed in accordance with a further embodiment of the invention, a temperature of 90 to 180 ° C. being reached in the film.
  • the film is cooled before being wound up.
  • a further advantageous embodiment of the invention is characterized in that the film is siliconized on one or both sides.
  • the plastic film thus produced can thus be used very well as a so-called release liner for a wide variety of purposes.
  • the process is carried out in such a way that polypropylene is extruded from an annular die, it being possible for several extruders to open into this annular die. However, it is also possible to provide further ring nozzles concentrically with the first ring nozzle. Additional layers of the same or different plastics, as well as adhesion promoters and the like, can be coextruded via the plurality of extruders or ring dies.
  • blends of PP with LLDPE or blends of PP with so-called compatibilizers can also be used.
  • Polyamide can also be used as the corlayer.
  • fillers for strength modification are also possible. Fillers can also be added which increase the breathability of the film, in particular in connection with stretching. In order to achieve an advantageous anchoring of a silicone layer, suitable polymers can be used.
  • the extruded tube is cooled to such an extent that relatively large film thicknesses are achieved during the blowing process. Film thicknesses of around 200 ⁇ m can be generated.
  • the hose dimensions are determined by calibration. Both a non-contact calibration and a calibration through the systems that contact the hose are possible.
  • the film can still be stretched out in tubular form after appropriate tempering, the stretching both transversely, i.e. Can be done biaxially in the circumferential direction, lengthways or simultaneously.
  • the film can then be laid flat and subjected to further stretching after appropriate tempering.
  • this involves longitudinal stretching, which is carried out, for example, via a nip.
  • transverse stretching, transverse and longitudinal stretching and simultaneous biaxial stretching are possible.
  • Siliconization is also possible inline or bilaterally, LH, LF, UV ESH or emulsion silicones being usable as silicone systems.
  • the film produced in this way is suitable as a release liner e.g. for labels and adhesive tapes or the like.
  • the film could be used excellently as a replacement for release paper.
