Packaging or packaging accessories that have an overall guarantee of initial opening or guaranteed unopened packaging

[Abstract] A packaging or packaging material with an overall guarantee of initial unsealing or guaranteed packaging, comprising a substrate (10) and one or more coatings coated on the substrate. As an example of the substrate (10), a deep-drawn molded package or a film-like material such as a metal film, a plastic laminate, a paper, or the like is used. The substrate has a reflective surface (11) that reflects visible light. The reflective surface (11) may also be provided with one or more layers of coatings consisting of one or several layers (12, 14, 16), for example a thin layer of a compound represented by the formula SiOx, where x is 1.5 - 2.0, layer thickness is 50-2000 nm (nanometer), and the free surface of the SiOx layer is covered with a layer of visible light semi-transparent metal reflective layer (13, 15, 17) with a layer thickness of 0.2-60 nm (nanometer). The light is reflected on the substrate and is reflected in different colors depending on the viewing direction and angle.

[Sovereign Items] 1. A method of manufacturing packaging or packaging accessories that has an initial unsealing or integrity guarantee and has a substrate (10) with a metallic surface (11) that reflects visible light. It is characterized by adopting a vacuum laminar method on the reflective surface (11) while simultaneously evaporating the silicon dioxide and semi-metal silicon as evaporation material from the evaporation source under vacuum to deposit a ceramic layer having a thickness of at least 50-2000 nm. The ceramic layer contains or consists of a compound represented by the formula SiOx, where x is a number between 1.5 and 2.0, and then is applied to a target of the ceramic layer or ceramic sequence by sputtering a target containing the corresponding metal to a thickness of 0.2-60 nm visible light semi-transmissive metal reflective layer, wherein the coating process is performed continuously, the substrate is first coated with a ceramic layer in the first chamber, and then passes through the narrow slit channel into another chamber to apply a metal layer by sputtering .
