Description

The invention relates to a packaging material made of plastic with a water vapor permeability> 15 g / (m ² · d), the outer surface is at least partially enclosed by a fitting on the packaging material outer surface equipment and labeling with a water vapor permeability <15 g / (m ² · d) ,

State of the art

Be plastic container in a variety of forms and designs as packaging for transport and storage of a variety of various packaged goods used.

at very many packaged goods It is necessary that the plastic packaging material has a sufficient water vapor barrier provides, on the one hand, an ingress of moisture through the Packmittelwandungen to Packgut out or from the inside of To prevent packaging in the environment.

in the the former case can be used, for example, for spreadable packaged goods Clumps come, so a convenient withdrawal of such damaged packaged goods from the packaging is no longer guaranteed. Furthermore, can by the penetrating water vapor the packaged goods are also chemically changed. For example, penetrating water vapor causes a deactivation or degradation of bleach and / or enzymes in detergents and cleaners. Not desired biological effects, such as the growth of bacteria or mold in the packaged goods, are increased by an Entry of water vapor possible.

Especially in aqueous packaged goods On the other hand, an insufficient water vapor barrier can lead to a Lead thickening of the packaged goods, when water vapor escapes through the packaging wall into the environment can. For such packaged goods This is especially in warm temperatures or direct sunlight relevant. this leads to then to a changed one flow behavior and concentrations in the liquid Packaged goods, whereby a precise dosage for the user is difficult. Due to the escaping water vapor, it may be due to the associated Volume loss to a denting of the corresponding container come what is aesthetical establish undesirable is.

Further can by the loss of fluid also soluble Ingredients of the liquid Products fail and settle at the bottom of the packaging. Finally is the creeping drop in volume associated with the escape of water unwanted in the bottle, especially if the bottle is transparent and a smaller one level level be perceived by the consumer.

Out establish resource conservation and the associated cost reduction Largest material savings in the formation of plastic-containing Packaging required. This usually leads to smaller wall thicknesses of the packaging, which regularly leads to a reduction in the Steam barrier of such a packaging and to a Reduction of stability, in particular the stackability, comes.

This is particularly critical for plastics of non-fossil origin, such as in starch-based plastics or polylactic acid, the usually a comparatively high water vapor permeability have, so that this sogg. Bio-plastics today for many packaged goods are not suitable.

Usually are used to produce such bio-plastics renewable, So used renewable resources. In addition to the possible Use of regionally available agricultural commodities for Production of bio-plastics, another advantage is that after use according to its intended use comparatively simple and rapid manner, for example by a composting according to DIN EN 13432, are biodegradable, so that in general a wider use and more widespread Use of bio-plastics desirable is.

To improve the steam barrier, it has been proposed in many places in the prior art to steam such bio-plastics, for example with SiO _x or aluminum, so that consequently the entire surface of a packaging material formed therefrom has a corresponding coating. In particular, the evaporation with aluminum, however, has a number of disadvantages. On the one hand, a metal-coated plastic film loses its transparency and on the other hand, they are usually unsuitable for use in a household microwave, so that an application for packaging and preparation of warm food regularly excretes. In addition, the vapor-deposited layer does not contribute to an increase in the structural stability of the molded container.

Furthermore, bio-plastics vapor-deposited with metals or SiO _x with increasing metal or SiO _x concentrations significantly lose their inherently good biodegradability. Especially in the case of metal-coated bio-plastics it has to be critically questioned whether the introduction of metals like aluminum into the environment, which are usually not naturally degraded but only accumulated, makes sense from an ecological point of view, especially against the background of the latest research results indicate a direct association of diseases such as Parkinson's disease or Alzheimer's disease with increased exposure to bioabsorbable aluminum.

One Another, still limiting factor in the use of bio-plastics is her still comparatively high price, which in particular in the use of bio-plastics the task as possible to use small amounts of such expensive plastic a desired one Train packaging to keep it at a competitive price can be made compared to conventional plastics. However, it becomes obvious that the demand for a preferably low primary material usage of bio-plastics, the need for adequate water vapor permeability to provide a sufficient stability of the packaging and to ensure a good biodegradability of the packaging, in direct contradiction to each other and so far not satisfied solved solved is.

Another method for improving the water vapor barrier effect is in DE 12 910 42 B disclosed. DE 12 910 42 B describes a substrate with a full surface applied to the substrate resin composition. As embodiments, different papers are used as a support on which thin layers of heated and thus flowable resin are applied over the entire surface, whereby an improved barrier effect against moisture permeability should be achieved, wherein the resin layers are firmly bonded to the substrate.

Task:

task The invention therefore is the water vapor barrier of a packaging material made of plastic with as possible low primary material usage resource-saving, cost-effective and easy to manufacture Way, so that both a structural reinforcement of the Packaging as well as an increase the water vapor impermeability is effected.
