Definitions

  • the invention relates to a device for the treatment of packaging films according to the preamble of patent claim 1, and to a method for preparing a packaging film on the subsequent packaging process.
  • packaging film which may be of different colors but not metallized.
  • the optical finishing during satinizing is visible through a uniform surface roughness of the paper.
  • the other effect, the refraction of the paper fibers, is the same as with metallized packaging film.
  • the packaging films considered here are useful not only for the packaging of cigarettes but also for cigars, as well as for foods such as confectionery, or for pharmaceutical products.

As a result, the working cycle of the embossing unit can be synchronized with the process cycle of the packaging system with relatively little effort.
  • Another already mentioned advantage for the subsequent packaging process is that refining the fibers of the packaging film is achieved by the satinization, whereby to a certain extent a reproducible folding of the paper during the packaging of the cigarettes is possible. This is necessary because even a slightly faulty folding angle increases the susceptibility to failure of the packaging process rapidly.
  • Such Device is from the already cited WO 02-076716 A1 of the same applicant, wherein the packaging film first passes through a first pair of rollers and then a second pair of rollers, so that reduced by the use of three rollers of the contact pressure and a better refraction of the paper content of the packaging material is achieved.
