Definitions
- Packaging film section packaging film, packaging and packaging product unit
- the invention relates to a packaging film, in particular for producing a packaging, having at least one packaging film section, wherein the packaging film section is a single-layer or multi-layered substrate and a printed functional layer formed from a printable material and at least partially forming an outer layer of the packaging film section which is designed to have antimicrobial and / or oxygen scavenging properties.
- the invention relates to a packaging, in particular a food packaging or a pharmaceutical packaging as well as a packaging product unit, comprising at least one product packed in a packaging.
- the first principle of operation is characterized by the fact that the antimicrobial agents and inhibitors integrated in the layer are volatile and are released over time from a material of the layer, whereby the antimicrobial effect is not only applied in the vicinity of the coating. teten surface but in the entire packaging volume arises.
- the second functional principle is characterized in that the antimicrobial active substances and inhibitors in the functional layer are spatially fixed in such a way that they can not escape from the carrier layer independently.
- the antimicrobial effect unfolds in such functional layers only by a direct contact of the packaged goods with the antimicrobially coated surface.
- WO 2006/133754 A1 describes an advanced process with which a technical surface can be produced with an antimicrobial agent-releasing layer.
- a solution of polyvinyl acetate, a preservative and a solvent is applied to the technical surface and dried on the technical surface to form the antimicrobial layer.
- oxygen scavengers In addition to the previously described functional layers with antimicrobial action, functional layers are known in which chemical compounds are integrated, which absorb oxygen and permanently bind chemically. Such chemical compounds are referred to as oxygen scavengers. Often the function of these scavengers is to create and maintain an oxygen-free atmosphere in the package to ensure extended shelf life of the package. For this purpose, the direct connections on the one hand remove the remaining oxygen, which is located in the packaging space, as quickly as possible, on the other hand provide the Compounds, if incorporated into the outer packaging material, provide an active barrier to oxygen migrating from outside into the packaging.
- WO 2007/051860 A1 now describes a novel paint material which has an oxygen scavenging property.
- This comprises a matrix consisting of organic polymers and at least one component that is reactive to oxygen after appropriate triggering.
- the functional layers described above have proven particularly useful in food packaging and pharmaceutical packaging.
