Definitions

  • the invention relates to a method for producing a film material which is provided with a hologram embossing, and to such a film material.
  • holograms or holographic structures are applied to the packaging material, in particular embossed therein, in order to make the packaging material and the product packaged with it distinguishable from other products.
  • a holographic embossing process is known from DE 37 44 650 A1, in which a substrate is provided with a lacquer layer, the material is then metallized, and finally a hologram is embossed through the metallization. Varnishes with special properties are required for such a process. Lacquers which cure under UV light are known for this purpose, the lacquers not being fully cured at the time of embossing, so that the embossed structure can be applied. Finally, the material is usually coated with a protective varnish and then it can be cut into narrow rolls. Alternatively, it is known to carry out the metallization after the point in time at which the partially hardened lacquer is embossed.
  • the protective lacquer applied as the top layer is required to protect the fine embossed structures and to produce the required abrasion resistance and lubricity of the material.
  • a disadvantage of the known holographic embossing processes is that they always require an additional, separate work step during the manufacturing process. In particular, the embossing process must be carried out before the protective lacquer is applied. The problem that arises here is that it is uneconomical to produce small lot sizes with changing embossing motifs, since the metallization and top coating only work for large lot sizes, i.e. H. large roles, economically.
  • Packaging material according to DE 299 00 043 Ul and DE 299 04 872 Ul also has a plastic layer as the outer layer, which leads to the problems mentioned in terms of economy.
  • the invention is based on the object of providing an economically improved process for producing a film material provided with a hologram, and an economically producible film material.
  • the film material is optionally first metallized.
  • the method according to the invention is fundamentally suitable both for metal foils, for example aluminum foils, and metal-paper composites, in particular aluminum-paper composites, but also for paper, which accordingly has to be metallized in a first process step.
  • d. H. is to be provided with a thin metal layer.
  • a lubricant is then applied as part of the method according to the invention.
  • the metallized or metal layer is embossed.
  • the step usually required according to the prior art to apply a suitable lacquer in which the embossed structures are formed is eliminated. Rather, it will be described in detail.
  • embossing made directly on the metal layer.
  • the lubricant ensures that the required structures without the risk of the metal peeling off can be trained.
  • the embossing is carried out directly on the finished film material, since the embossing is not carried out on a lacquer which is subsequently to be hardened, nor is a top coat or protective lacquer applied subsequently required. It has been found in tests that the embossed surface can form the uppermost layer of the film material produced according to the invention, with the exception of the lubricant layer which is present at least in residues even after embossing.
  • Lubricants which can be used in connection with the present invention preferably belong to the following chemical classes: paraffins, polyethylene waxes, polypropylene waxes modified with maleic anhydride, ester and acid waxes, amide waxes, polytetrafluoroethylene waxes, polytetrafluoroethylene / polyethylene waxes, ethyl vinyl acetate Copolymer waxes, natural waxes, fatty alcohols, fatty acids, metal soaps, fatty acid esters, solid acid amides, siloxanes and sulfated oils. According to the invention, they can be used as a single compound or in mixtures which are compatible with one another. Most lubricants are commercially available and can be used directly without further preparation.
  • the lubricant is a paraffin, it is preferably selected from predominantly branched-chain liquid hydrocarbons or from predominantly straight-chain solid hydrocarbons.
  • Polyethylene waxes as lubricants are advantageously selected from polyethylenes with an average molecular weight of 2,000 to 12,000 or from air-oxidized low molecular weight polyethylenes.
  • a preferred natural wax is carnauba wax.
  • Stearic acid, 12-hydroxystearic acid and montanic acids mixture of long-chain carboxylic acids with 26 to 33 carbon atoms.
  • Metal soaps are also suitable as lubricants. Calcium stearate, magnesium stearate and zinc stearate are preferably used.
  • Fatty acid esters as lubricants are preferably selected from fatty acid esters of short-chain monohydric alcohols, fatty acid esters of long-chain monohydric alcohols, glycol
  • Fatty acid esters Fatty acid esters, glycerol fatty acid esters, montanic acid ester waxes, solid or liquid high molecular weight mixed esters or from esters of polybasic carboxylic acids.
  • Typical representatives of this class of compounds are n-butyl stearate, stearyl stearate, propylene glycol onooleate, glycerol monooleate, glycerol monostearate, distearyl adipate, distearyl phthalate and polycondensates
  • Fatty acid amide selected from oleic acid amide, erucic acid amide or stearic acid amide, or N, N '-bis-stearoyl-ethylenediamine.
  • the lubricant is usually applied by applying it as a dispersion and then drying it.
  • the solvent used evaporates, leaving a comparatively firm application of lubricant.
  • a film material with a hologram embossing can also be produced, which consists of a metal-paper composite, in particular an aluminum-paper composite.
  • a composite material is to be coated with lubricant on the foil side, that is to say the metal side, within the scope of the method according to the invention and can also be processed according to the invention without the need for a coating application and processed into a foil material with hologram embossing.
  • the lubricant For the application of the lubricant, it has proven to be advantageous to apply the lubricant in an amount of the order of 0.02 g / m 2 . This enables the required machinability, in particular the possibility of embossing, to be ensured in an economically advantageous manner.
  • the method according to the invention since the method according to the invention does not require a final application of protective lacquer, which may require hardening, the method according to the invention prefers a cutting process with embossing in one operation with further economic advantages.
  • the material according to the invention can be used on a combined embossing and cutting machine, in particular a roll cutting machine, getting produced. The material can then be wound up into at least one roll with little effort.
  • the film material described in claim 5 has a metal layer provided with a hologram embossing and a lubricant layer which is at least partially formed on the finished film material on the metal layer.
  • the method according to the invention is reflected in the associated film material in that only the
  • Metal layer and / or the lubricant layer form the top layer of the material.
  • no protective lacquer is required on the film material.
  • Inner film of cigarette packaging can be used.
  • the film material according to the invention can be found in further claims.
  • it is preferred for the film material that it is a metallized paper, a metal, in particular an aluminum foil or a metal-paper composite, in particular an aluminum-paper composite.
  • the required machinability for producing the film material according to the invention can be ensured in that the finished material has a lubricant order in the order of 0.02 g / m 2 .
  • the film material according to the invention is present as a roll material.
