- a heat-crosslinking material or a solvent-based material which uses, for example, water as a solvent and cures by evaporation of this solvent.
- the material used for the intermediate or adhesive layer 8 may also contain nanoparticles, for example nanofibers or nanotubes, whereby a defined roughness on the surface to be printed is produced for improved adhesion of the print 17.
- the respective print 17 or the print layer formed by it is as problem-free as possible between the remaining on the respective bottle 2 and in this case preferably transparent intermediate or adhesive layer 8 or the intermediate or Adhesive layer 8 together with the imprint 17 of the respective bottle 2 can be easily removed.
- the respective imprint or the printing layer 17 and the intermediate or adhesive layer 8 are adjusted by material selection and / or by the type of drying and / or crosslinking, for example,
- the material for the intermediate or adhesive layer 8 is chosen such that this can be stretched before blow molding the bottles 2 onto the preforms 3 and dried or hardened intermediate or adhesive layer 8 with the respective section 3.2 during blow molding. without there being any cracks in the intermediate or adhesive layer 8 or a detachment of this layer from the bottle wall 2.3.
- the coating of the preforms 3 with the material forming the intermediate or adhesive layer 8 is format-independent, i. without conversion, preforms 3 of different sizes, i. different length and / or thickness for the production of bottles 2 or other containers of different size and / or shape coated or provided with the intermediate or adhesive layer 8.
- FIG. 6 shows, as a further embodiment, a treatment station 7a which differs from the treatment station 7 in that the application of the intermediate or adhesive layer 8 or the material forming this layer takes place not by means of a spray device but by using a roller 18, which is provided by an applicator, not shown on its roll surface with the intermediate or adhesive layer 8 forming material and at which the respective preform 3 rolls with the circular cylindrical or substantially circular cylindrical outer or outer surface of its section 3.2. It was assumed above that the intermediate or adhesive layer 8 before the transfer of the preforms 3 to the blow molding machine 14 or to the local blow molds 12 cured or substantially cured, ie in particular dried and / or crosslinked, for example by the action of heat on preheating section 10 (preform oven).
