Definitions

the present invention relates to a method for producing a metallized composite and a metallized composite.
certain goods such as cigarettes, coffee or the like, are usually packaged in a composite which comprises aluminum and plastic films or also paper.
the aluminum foil which has a water vapor permeability of approximately 0 g / m2 ⁇ d, acts as a barrier for gases and moisture.
the water vapor permeability of such a composite is around 40-100 g / m2 ⁇ d (measured in accordance with DIN 53122), which is, however, not sufficient for many applications since, for example, for aromatic packaging of cigarettes and coffee, a water vapor permeability of ⁇ 2 g / m2 ⁇ d is required.
barrier coatings include, for example, latex dispersions with additions of pigments and polymers with a basis weight of approximately 18-20 g / m 2.
barrier coatings as well as a primer layer, a metallization layer and a topcoat are then applied to this base paper, which should ensure the required water vapor permeability of ⁇ 2 g / m 2 ⁇ d.
the composites provided with barrier coatings are very expensive compared to the composites with aluminum foil.
the required low water vapor permeability of almost 0 g / m2 ⁇ d is achieved in that the coating processes known per se, primer and metallization are carried out twice. As has been found, an excellent barrier effect is achieved by applying a second primer and a second metallization to the first primer layer.
the composite material according to the invention is ecologically harmless and not cost-intensive.
a paper is known from JP-52012311, which is provided with an aluminum metallization.
the base paper is coated with a 15 ⁇ m thick polyethylene film that is rolled.
a corona discharge increases the surface energy of the polyethylene film and then the film is metallized with aluminum.
the base material can be paper or plastic film. Since the base material does not require any special barrier coatings due to the structure according to the invention, customary, inexpensive paper or customary plastic film can be used.
the basis weights or layer thicknesses specified in claim 5 can be provided.
Such a composite results in a water vapor permeability ⁇ 2 g / m2 ⁇ d.
the total amount of primer and top coat applied is less than 5 g / m2. This is a significant advantage compared to the total application quantity of 20-25 g / m2 with the conventional solutions, since this makes the material easier to recycle.
the composite according to the invention Due to the extremely low water vapor permeability of the composite according to the invention, it can be used particularly well for packaging products containing aromas, gases or moisture.
the figure shows a partially sectioned cross section through a composite according to the invention.
the composite shown in the figure consists of a base material 10 in the form of conventional coated paper with a basis weight of 50 g / m2.
a first primer 12 in the form of a coating of primer lacquer with a basis weight of 1.8 g / m 2 is applied to the base material 10.
a first metallization 14 with a layer thickness of 300 ⁇ is evaporated onto the first primer 12.
a second primer 16 is applied from a primer with a basis weight of 1.8 g / m2.
a second metallization 18 with a layer thickness of 300 ⁇ is in turn evaporated onto the second primer 16.
a cover layer 20 in the form of a top coat with a basis weight of 1.0 g / m 2 is applied to the second metallization 18.
the water vapor permeability of this composite is ⁇ 2 g / m2 ⁇ d.
the material of the base coat and that of the top coat is a nitrocellulose paint.
the metallization consists of aluminum.
