Definitions

• the present invention relates to films and is concerned with security features which can be applied to foils around the foil or wrapped in the foil Protect goods from unauthorized imitation in a simple manner.
• counterfeit goods are a constant growing problem.
• Such counterfeit products often become deceptive packaged in a similar way to the original goods in order to deceive potential buyers and to make them believe they are buying originals.
• the manufacturer of the original products escapes business.
• the owner of the rights to the product has been cheated of its intellectual property.
• the imitations are often are of inferior quality and thus a not inconsiderable one for the manufacturer Add Image Loss.
• the lower quality can turn into claims of product liability, so that it is up to the manufacturer of the original to prove that the good causing the damage does not come from him. From these For the sake of clarity, it is desirable to label original products so that it the consumer is able to recognize the originality and that it is in the It is possible to prove the originality in the event of damage.
• the outer packaging has already been used as carrier media for security features. Thats how it is suppost to be Packaged goods themselves cannot be equipped with the feature and you can e.g. several products from a branded article manufacturer with the brand-typical security feature provided without getting into the manufacturing processes of each individual product to have to intervene.
• embossed holograms applied to the packaging are used in exactly the same way as security features introduced via tear strips. The latter are not always desired because the packaging machines that are already in use are not always designed for the use of tear strips. Embossed holograms or security labels must be carried out in a separate step be applied, which causes additional effort and thus additional costs.
• the invention therefore relates to printed plastic films, if appropriate combined with another material, characterized in that it are printed with a micro script. This imprint of the micro script sets Security feature in the sense of the task.
• the films come from polypropylene, polypropylene copolymer, polypropylene terpolymer, Polyester, polyamide, polyethylene, polyethylene copolymer, Polyethylene terpolymer, polyvinyl chloride, vinyl chloride copolymer, vinyl chloride terpolymer, Polystyrene, polystyrene copolymer, polystyrene terpolymer, polycarbonate, Polyketone, polymethyl methacrylate, polymethyl methacrylate copolymers or cellophane in question.
• Biaxially oriented carrier films made of polypropylene are preferred, Polypropylene copolymer, polypropylene terpolymer, polyester or polyamide used.
• composite films from these carrier films in any combination as well Layer structures of these carrier films with other materials such as another or the same plastic metal, especially aluminum, or ionomer as slides in question.
• the composites can be laminated with adhesive Coextrusion or evaporation or a combination of these processes become.
• the films can also be laminated with paper as a composite packaging material, the Lamination can be done both before and after printing.
• the paper can also be the print carrier, which is covered by a plastic film with additional Properties.
• Another object of the invention is a method for producing a optionally laminated film of the plastic, in which the film with a Micro script printed and optionally laminated with other foils.
• printed packaging films are produced in such a way that a carrier film with both the standard print image and with the security feature. So it works by using suitable ones Printing forms, within an already necessary work step Integrate security feature.
• the print can be carried out as frontal as well as counter print.
• the printing ink can also be arranged between the layers his.
• the carrier film can have a thickness between 10 and 300 microns and a width between 20 and 2000 mm.
• the thickness is preferably between 15 and 60 ⁇ m and Width between 600 and 1400 mm.
• the carrier film can be printed in one or more colors. It is coming any printing process that can be used for foils. Especially done printing in typical packaging printing processes such as offset, screen, flexo, UV flexo or gravure. Especially in offset or gravure printing, especially in Gravure printing.
• the micro fonts are fonts whose letter size is less than 0.7 mm. Especially those with a size smaller than 0.3 mm. All sizes smaller than 0.26 mm are particularly preferred.
• the fonts can be in any Way to be integrated into the printed image.
• the micro fonts can be in positive writing as well as in negative writing to be printed.
• One embodiment has fonts of normal size, ie larger than 0.7 mm, which in turn are made up of micro fonts. When inspecting the Normal "writing with a strong magnifying glass or a microscope will make the micro writing recognizable.
• the packaging materials according to the invention can advantageously be used Products are protected against counterfeiting.
• the sense of the security element lies in judging when counterfeits occur their lack of originality to be able to prove or also to the consumer, an intermediary or to allow an authority like customs or police to use simple means Recognize the originality of a product.
• the printing on one side of the carrier film can be done with the known printing machines respectively.
• a printing unit is used for printing the micro script designed.
• Another object of the invention is therefore the use of the invention Foils as packaging material.
• a lettering in micro script (Font size: 0.2 mm) printed.
