Definitions
- the present invention relates to a packaging material with a hologram-like appearance and the use of the packaging material.
- the object of the present invention is to propose a packaging material which has a hologram-like appearance in whole or in part on a package, at least on its outward-facing side.
- the packaging material is a multi-layer material with a layer structure, comprising: a) a metal foil or metallized plastic foil embossed over the whole or part of the surface and b) a single or multi-layer plastic layer, which is at least partially transparent, with the packaging Plastic layer b) forms the outer layer and the embossing of the metal foil or metallized plastic film a) is visible through the transparent areas of the plastic layer b).
- the plastic layer b) points towards the outside of a finished packaging, made from the packaging material at hand.
- Further functional layers for example made of plastic and / or paper, can be arranged on the free side of the metal foil.
- an iron, steel, copper, silver, gold and in particular an aluminum foil can be used as the metal foil.
- the foils can have a thickness of, for example, 7 to 100, expediently 7 to 40 and advantageously 8 to 40 ⁇ m.
- the aluminum foils can be made of pure aluminum with a purity of, for example, 98.3% and higher, or can be made of an aluminum alloy, for example of the types - 2 -
- the plastic of the film can e.g. made of polyamides, polyesters, polyolefins, polyvinyl chloride, polycarbonates, etc.
- the thickness of the plastic films can e.g. from 7, preferably 2, to 100 ⁇ m.
- the metal foil or the metallized plastic foil have an embossing.
- the embossing can be applied over the entire surface, over part of the surface or partially.
- the embossing can be done on the foils by embossing rollers.
- the embossing rollers have the desired embossing pattern and the foils are placed between the embossing roller and a counter pressure roller, e.g. with paper coating.
- the image of the roll embossing is transferred to the film.
- the embossing can be a grid, regular or irregularly repeating patterns, damask embossing, worm embossing, hammer embossing, etc.
- embossing is possible, such as fonts, figurative and abstract representations, pictorial representations, logos or combinations thereof. It is also possible to color or print both embossed areas and, in some cases, intervening non-embossed areas. This allows the optical effect of an embossing to be changed, e.g. amplified, weakened or changing with the incidence of light.
- the single-layer plastic layer can be a plastic film produced by calendering, for example by hot calendering.
- the thickness of the calendered single-layer plastic film can be 20 to 200 ⁇ m.
- Thermoplastic materials such as polyolefins, can be used as plastics.
- the plastic layer can be an at least two-layer plastic film produced by coextrusion.
- the layer thickness of each individual layer can be 20 to 200 ⁇ m.
- Thermoplastic materials such as ionomer resins (Surlyn) and polyolefins can be used as plastics.
- the plastic layer can be a film of thermoplastic plastic applied to the metal foil by lacquer lamination. A solvent-based or solvent-free lacquer lamination is advisable.
- the lacquer lamination can contain or consist of a polyolefin.
- a film made of thermoplastic can also be applied to the metal foil by means of a melt extrudate made from a thermoplastic.
- the melt extrudate can contain or consist of a polyolefin.
- the amounts of lacquer or melt extrudate used can be from 3 to 80 g / m 2 and expediently from 30 up to 50 g / m ⁇ .
- the film made of thermoplastic can be a monofilm or a two-, three- or multi-layer film, respectively.
- the film contains polyolefins or consists of polyolefins.
- the total thickness of the thermoplastic film is, for example, 20 to 200, advantageously 40 to 150 and preferably 90 to 120 ⁇ m.
- the plastic layer is expediently transparent or at least partially transparent.
- the plastic layer can be colored or clear.
- the plastic layer can be printed. In the case of lacquer lamination, the film can be printed and or counter-printed. Printing and any non-transparent partial areas of the plastic layer that are provided are correspondingly arranged such that at least partial areas of the embossing in the metal foil each remain visible through the transparent parts of the plastic layer.
- Preferred thermoplastic materials are, for example, polyolefins.
- polyolefins are polyethylenes, for example high density polyethylene (HDPE, density greater than 0.944 g / cm 3 ), medium density polyethylene (MDPE, density 0.926-0.940 g / cm 3 ), linear medium density polyethylene (LMDPE, density 0.926-0.940 g / cm 3 ), low density polyethylene (LDPE, density 0.910-0.925 g / cm 3 ), linear low density polyethylene (LLDPE, density 0.916-0.925 g / cm 3 ), or mixtures thereof.

- polystyrene resins are polypropylene, such as amorphous, crystalline or highly crystalline polypropylene, atactic or isotactic polypropylene and mixtures of the polypropylenes mentioned, cast polypropylene, poly-1-butene, poly-3-methylbutene, poly-4-methylpentene and copolymers of these, such as polyethylene with vinyl acetate, vinyl alcohol or acrylic acid.
- copolymers known as ionomer resins, of ethylene with about 11% acrylic acid, methacrylic acid, acrylic esters, tetrafluoroethylene or polypropylene.
- the polymers mentioned also include the corresponding statistical copolymers, block copolymers or olefin polymer / elastomer mixtures.
- Films are undrawn and preferably axially or biaxially stretched films.
- the films can be a monomaterial or a two-, three- or multi-layer laminate.
- Appropriate packaging materials have a layer structure, comprising: a) a metal foil embossed in whole or in part, in particular an aluminum foil, b) a multilayer plastic layer composed of b) a lacquer lamination or a melt extrudate and b2) a foil containing a polyolefin.
- Packaging materials preferably have a layer structure comprising: - 4 -
- the free side of the metal foil or the metallized plastic foil can be covered with additional functional layers.
- the selection of the functional layers depends on the intended use of the packaging material.
- one or more further plastic layers and / or a paper layer or a paper and one or more plastic layers and / or further metal foils or metallized plastic films can be arranged on the free side of the metal foil or the metallized plastic film.
- the plastic layers can be applied, for example, by lacquer lamination, by calendering or by coextrusion. Papers are usually applied by lacquer lamination or gluing.
- the packaging material according to the invention can, for example, be coated with plastic layers on the free side of the metal foil or the metallized plastic film by painting, calendering, by lacquer lamination or by coextrusion.
- the plastic layers advantageously contain thermoplastic materials, such as the polyolefins mentioned above, the polyethylenes and polypropylenes being particularly suitable. Paint or lamination can be carried out in quantities of e.g. 3 to 80 g / m ⁇ can be applied.
- Plastic films can for example have a thickness of 20 to 150, advantageously 20 to 100 and preferably from 50 to 80 microns.
- the functional layers arranged on the free side of the metal foil or the metallized plastic foil point towards the inside of the packaging, i.e. on a packaging made from the present packaging material. against the content in the packaging. It may therefore be advantageous to provide a barrier layer in the functional layers in order to prevent liquids, vapors, aromas, etc. from penetrating into the functional layer.
- a sealing layer or sealable layer can be provided as the outermost layer facing a packaging and / or the innermost layer pointing towards the contents of a packaging. If the layers described are not sealable per se, an additional sealing wax or sealable film can be used.
- the packaging material can be used for various types of packaging.
- the present invention therefore advantageously also relates to the use of the packaging material for tubes.
- the layer structure contains a particularly suitable packaging material for tubes:
- the film b2) can be provided on one or both sides with a partial printing pattern.
- the functional layer a ⁇ ) can be a plastic layer applied by calendering, by lacquer lamination or by coextrusion onto the metal foil or the metallized plastic film.
- a packaging material suitable as an example for the production of tubes, contains the layer structure:
- a film containing polyolefins in particular polyethylenes or polypropylenes, in thicknesses of 20 to 200 ⁇ m.
- the polyolefin film represents the functional layer a ⁇ ) the inside and the polyolefin film b2) the outside of the tube, and in particular the tube tube.
- the polyolefins are generally sealable. Therefore, the tube tube can be produced from the packaging material by applying sealing seams, but also by gluing seams.
- the present packaging material is therefore particularly suitable for producing the tube of a tube.
- the choice of material and the structure of the tube head Tube head The attachment of the tube head and the closing of the tube end can also be done by sealing or e.g. also by gluing or welding.
- a typical packaging material for tubes has the following layer structure:
- a functional layer which points inwards on the tube made of a polyethylene film with a thickness of 40 to 80 ⁇ m, a lacquer coating or a melt extrudate made of polyethylene in amounts of 30 to 50 g / m 2 , a) a whole or part embossed Aluminum foil or a whole or partial embossed metallized plastic film, in a thickness of 8 to 40 ⁇ m, b) a multi-layer transparent plastic layer made of b ⁇ ) a lacquer lamination or a melt extrudate made of polyethylene in quantities of
- FIG. 1 shows a section through an example of a packaging material 9 according to the invention.
- the embossed metal foil 10 is coated with a layer 11 of a melt extrudate from a low-density polyethylene on the side that later points outward on the packaging. Overlying this is a film 13, such as a three-layer film made of polyethylene. Possible printings in the form of a print 15 applied to the surface and a counter print 16 are shown.
- the film 11 and the film 13 are transparent and the embossing 17 is visible through the plastic layer made of melt extrudate 11 and film 13.
- a further layer 12 of a melt extrudate and another foil 14, for example a polyethylene foil is attached to it. If a tube or at least the tube tube is produced from the packaging material 9, the film 14 points to the inside of the tube and thus to the contents.
- Layer 12 and film 14 can be transparent or opaque. It can be advantageous to provide a barrier layer in or on the film 14 in order to avoid that ingredients or parts thereof diffuse into the plastic layer and lead to premature spoilage of the ingredients or delamination of the packaging material.
- the viewer of a tube made of the packaging material according to the invention can see, in addition to any print image of print 15 and reverse print 16, in particular the embossment 17 which shines through the plastic layer.
- the metallic sheen and the reflection of the metal foil 10, and in particular the reflection influenced by the embossing lead to optical effects which can be most easily compared with the visual impressions achieved by holograms.
- print 15 and Konterdruckl ⁇ and / or by only partially transparent and / or colored foils 13 and / or colored embossing 17 in the metal foil 10 a variety of graphic design options for packaging or. Achieve tube exterior.
- a packaging material can be produced, for example, by embossing the metal foil 10 by means of embossing rollers, lamination on one side by means of a melt extrudate 11 of the plastic foil 13 on one side of the metal foil 10 and, in a further operation, laminating it on by means of a melt extrudate 12 of the further plastic foil 14 free side of the metal foil 10.
- the order of coating can be changed or carried out simultaneously.
