Definitions
- the present invention relates to a flexible packaging material, in particular a sealable and / or sterilizable packaging material, made of a monofilm or a film composite with one or two-sided printing, and a method for its production and the use of the packaging material.
- the printing of flexible packaging materials such as paper foils, plastic foils, metal foils or film composites, from two or more of the aforementioned packaging materials is conventionally carried out under high pressure, e.g. Flexographic, gravure, planographic printing, e.g. Offset printing, or in printing, e.g. Screen printing.
- the printing inks are applied to the packaging material by means of a printing cylinder, printing plate, screen or the like.
- the amount of printing increases according to the number of colors.
- the print sample must be transferred to the packaging material using one or more printing forms.
- the printing processes are mature and enable rational production of large quantities of packaging materials with uniform printing motifs.
- a heat seal lacquer is used for sealable packaging, which begins to seal only at around 160 ° C.
- packaging materials must be sterilizable for certain applications and consequently heatable to temperatures above 100 ° C, usually around 120 ° C, without being damaged.
- the object of the present invention is to propose a heat-resistant or heat-press-resistant packaging material with photoelectric printing and a method for its production.
- the packaging material contains a partially or completely transparent, heat-resistant coating layer applied at least to the printing by means of an electrophotographic process and the coating layer is produced from a toner which cures by ultraviolet or electron radiation.

- the principle of the electrophotographic process consists of the following sub-steps:
- the photoconductive surface layer of a photocarrier for example a copying drum, is evenly charged in the dark.
- the photoconductive The layer is exposed to a light source which reproduces the printed image as an exposure pattern, the exposed part of the photoconductive layer being discharged. A charge image corresponding to the printed image is created.
- an electrostatically charged toner is transferred to the charge image, the toner particles charged opposite to the charge of the photoconductive layer being drawn by the electrostatic forces acting on the charge image on the photocarrier while reproducing the printed image.
- the transfer of the toner to the charge image is preferably carried out by means of a method based on the so-called EMB technology (electro-magnetic brush technology), as is used in particular in the two-component developer system.
- a so-called carrier consists of ferromagnetic particles, the toner particles being bound to the carrier by triboelectric forces.
- the developer system consisting of the carrier and the toner particles adhering to it is applied via a rotating magnetic roller opposite the photo carrier or the copying drum. Due to the magnetic forces acting between the magnetic drum and the carrier, the developer system is pulled in a chain-like manner to the magnetic drum and forms a brush-like arrangement, also called a magnetic brush.
- the magnetic brush sweeps over the photo carrier and creates a so-called brush effect, by means of which the toner particles are transferred to the charge image of the photo carrier with the aid of electrostatic forces.
- the toner e.g. B. by means of corona discharges, transferred from the photocarrier to the substrate to be printed.

- the UV or EB curing toners contain so-called initiators, e.g. Photoinitiators in UV-curing toners, which burst with UV or electron beams when the energy is bombarded and cause the toner application to polymerize immediately.
- initiators e.g. Photoinitiators in UV-curing toners, which burst with UV or electron beams when the energy is bombarded and cause the toner application to polymerize immediately.
- the toner particles are transferred to the substrate in a so-called heating station, e.g. after the transfer from the photocarrier. by means of IR (infrared) radiation or I TR (near infrared) radiation, in particular by means of heated rollers, on e.g. Heated to 70 - 80 ° C and melted if necessary.

- the toner application for producing the coating layer can be carried out in a targeted manner with different layer thicknesses in the electrophotographic process, e.g. in the form of a negative image of the printed image, so that a thicker toner layer is applied to the non-printed surface areas and a thinner to the printed surface areas.
