  • Recycling of a film web is also possible after forming into a multilayer product in the prior art, but only to a limited extent because it is not sorted.
  • new film layers are again produced from the recycled material of the used film layers after separation or singulation, so that the once used or used materials can be returned to the production process of identical or similar products or multilayer products.
  • the once purchased material for the manufacturer of generic products is not lost, which can also reduce the production costs also not insignificant.
  • the beneficial effects can be achieved in a simple manner in the sense of the invention in that the individual film layers rest only temporarily adjacent to one another, without interacting with one another in a conclusive manner; be it by melting of their surfaces (extrusion) and / or by surface or full-surface adhesion or bonding of their surfaces (lamination) or the like.
  • the individual film layers do not permanently adjoin one another, at least before a forming process. They interact only temporarily with each other, in the Essentially only immediately before, during and immediately after the actual transformation process, unless this is specifically manipulated by a special process variant so that areas can remain permanently connected to one another.

  • the term "releasable" introduced in this context describes that the individual film layers can be lifted off from one another without destroying each other.At least this applies to the film layers immediately after the forming process, in particular with respect to produced film layer residual gratings, from which the finished molded products are separated are.
  • the multi-layered nature of a multilayer product relates in particular to its walls, which, viewed in cross section, are presently formed by a plurality of contiguous layers.
  • thermoforming preferably produced by thermoforming.
  • overpressure and / or vacuum techniques can be used to assist both hot working and cold forming in order to give the manufactured products an even more concise geometry.
  • a preferred method embodiment for all claimed variants of the method provides that the multilayer product is molded in a thermoforming process and / or in an overprinting process. As a result, contours and geometries on multilayer products can be made even more concise and precise.
  • film layer in the context of the invention describes a substantially “endless” wound into a coil film web, or even already cut to size film web blanks, if it seems practicable.
  • This film layer is monolayer within the meaning of the invention.
