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 considerable loss of image for the manufacturer inflict.
• the lower quality can lead to claims from the 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.
• it is desirable to label original products so that it is clear to the consumer becomes possible to recognize the originality and that it is in the event of damage it is possible to prove the originality.
• the outer packaging has already been used as carrier media for security features. So the packaged goods themselves are not equipped with the feature and you can e.g. several Products from a branded article manufacturer with the typical security feature provided without interfering in the production processes of each individual product have to.
• 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 is based on are printed on one side with a special security color.
• the imprint with such a color represents a security feature in the sense of the task represents.
• 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 Metal, in particular Aluminum or ionomer can be used as foils.
• the networks can be coextrusion or vapor deposition or an adhesive lamination Combination of these processes can be made.
• 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 an optionally laminated film of the plastic, in which the film with a special security color printed and if necessary with additional foils concealed.
• 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 flexo or gravure.
• the security colors used can be of different colors Trade effects.
• thermochromic colors in question at a given Temperature reversibly or irreversibly changes color
• Daylight fluorescent colors whose luminosity depends on the UV light portion of the lighting, so that the Originality with the technical aids of the color copier that is widely used today can be checked
• Luminescent colors that absorb UV light and emit longer-wave, visible light which when illuminated with a UV lamp a certain color impression can be achieved, the light emitting can either be done very quickly after absorption, so that one is free from fluorescence speaks or it can stop for a longer period of time, so that one of Phosphorescence talks
• Infrared colors that have a characteristic absorption behavior under IR light show, so that a differentiation of colors is possible, the appear identical in daylight
• photochromic colors by irradiation with UV light changes its color reversibly
• metameric colors whose hue depends is from the observation angle.
• 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.
• One or more printing units, depending on the number of desired Effects are filled with security color and like a conventional color integrated into the printed image.
• Another object of the invention is therefore the use of the invention Foils as packaging material.
