Holographic sealing foil is ideally suited for permanently protecting various substrates against counterfeiting. Depending on the type of application,the foil is transferred to the substrate in a special process and cannot be removed afterwards. The hologram is permanently attached to the product. This application method is used for large print runs and purely by machine.
Cold transfer films are similar in structure to the familiar heat-seal films, but here the holographic layer is transferred cold to the substrate in a special UV-supported process. By using different UV-curing varnishes and special additives, the properties of the finished label can be determined and defined for various applications. Cold transfer film can be transferred very precisely in-line to specific areas in the printing process and no die-cutting is required. This means that holographic effects can be integrated into fast-running UV presses without much extra effort.
In heat-sealing films, the holographically embossed layer is supplied with various other coatings and a thermally reactive adhesive layer on a polyester carrier. Using heatable pressure rollers or stamps, the film is permanently bonded to the substrate to be coated. The polyester carrier is then peeled off again. Heat-sealing films cannot be removed without destroying the layers and are therefore very popular for securing paper documents. For example, on banknotes, tickets, admission tickets, etc.
Chrome-based transfer foils have a high resistance to external influences and are therefore designed for special applications in heavy-duty environments. Due to the unique manufacturing process, CBH (chrome based holograms) are resistant and tamper-proof and are often used in high security license plates due to their durability and longevity under outdoor conditions.
HRI Stamping Foils are a material that can be used in transparent high security holograms. HRI foils are metallized with zinc sulfide instead of aluminum, which gives the foil a transparent appearance. This material is diffusion free and has a higher consistency of holographic effects compared to other holograms, ideal for applications in pharmaceutical packaging, bank documents, ID cards and academic certificates.
We supply exclusive films in large format, which are not available on the general market. These are especially the foils produced in NOI process, as transparent foils (HRI), or seamless (seamless).
The carrier material for holographic foils is usually a plastic film that can be thermomechanically embossed and has resistant properties. The holographic relief structure is then well formed and provides high light refraction and thus an excellent optical effect. The film, which is made of coated PET or PP, is embossed with a holographic embossing shim using the roll-to-foil process and finished with a special coating for the various applications.
With special patterns in the NOI segment (Nano Optical Imaging), a certain protection against counterfeiting can also be guaranteed, as these foils can only be obtained from a production facility.
PRINTABILITY OF HOLOGRAM FOILS
All holographically enhanced packaging and lamination films are ideally suited for subsequent printing and can be used in your existing system.
Depending on the application, the pre-treatment takes place on the metallized, or the film side.
Due to their reflective properties and light refraction, our holographic films enhance packaging and displays to create an extraordinary product at the point of sale.
Our packaging and laminating films are delivered holographically embossed and pre-treated for printing.
The minimum quantity for a specially embossed film is between 10,000 - 50,000 square meters, depending on the material and pattern. We are constantly working on new and unusual patterns to offer our customers unique design variations. Discover our current pattern portfolio in the:
Holographic transfer and seal foils, just like hologram labels, can be produced with an individual design, especially for you and according to your requirements. The transfer foils are, according to their property of insoluble bonding with the substrate, the ideal security feature for larger production runs, in which the hologram application can be carried out economically profitable "in-line".
