Definitions
- the present invention relates to a method and a device for printing on films and a film composite produced thereby.
- Films are used in the packaging industry, with both monofilms and composite films being used here.
- the films used are printed to give the consumer information about the product, the manufacturer or the brand and to create an aesthetic appearance.
- In addition to the previously common printing processes such as gravure digital printing is becoming increasingly important and is already used for example in labels, paper applications or so-called shrink sleeves.
- a use of the digital printing method is so far only possible if the composite printing on the inside of the print carrier takes place. However, this then requires further production operations such as lamination, curing, etc.
- Digital printing for the printing of foils is basically already known.
- Hewlett Packard offers a digital printing machine called Indigo, which is basically also suitable for printing on film.
- Indigo a digital printing machine
- the print side is first corona-pretreated, then applied to an aqueous solution based primer and finally the printing of the film is done in digital printing.
- the films so printed do not have the required thermal and mechanical resistance expected from sealable films.
- the corona pre-treatment before priming and before printing leads to a particularly high mechanical and thermal stability of the printed film.
- primer is an organic solvent-based primer.
- the primer is a two-component primer.
- the primer may also be a 1-component primer based on polyurethane or polyvinyl butyral (PVB).
- the resist is an organic solvent-based resist.
- the resist is a two-component resist.
- the primer is applied at a thickness of 0.1 to 1 g / m 2.
- the resist is applied at a thickness of 0.3 to 2 g / m 2.
- a radiation-curing protective lacquer is used as a protective lacquer, wherein the protective coating is cured by means of electrobeam curing, or the protective coating is cured by means of UV curing.
- the invention comprises a film composite or film produced by a method according to an embodiment of the invention.
- the embodiments allow the printing of web-like composites (multilayer laminates) or films for flexible packaging of food, non-food, pet food, pharmaceutical or medical applications.
- These composites generally consist of at least 2 different films containing plastic films, and / or metal foils, and / or paper foils. According to one embodiment, it may also be monofilm.
- the pressure side of this composite (multilayer laminate) or the film is first processed to achieve a better primer adhesion on the pressure side with a corona pretreatment, which takes place according to an embodiment inline.
- a corona pretreatment the surface to be treated is exposed to an electric corona discharge for a short time.
- a commercially available device for corona treatment can be used.
- This pre-treatment serves to clean the surface of the print substrate of materials which have been deposited by set-off from the seal side or migration to the surface.
- polar molecules are formed on the surface, to which the primer can then better bind.
- a primer or adhesion promoter is first applied to the printing side of this composite (multilayer laminate) or the film to achieve a better ink adhesion on the printing side according to an embodiment.
- the order takes place according to an embodiment of 0.1 to 1 g / m2 dry.
- a solvent-containing primer is used, or a primer based on an organic solvent.
- primers based on an organic solvent an increased mechanical and thermal stability of the printed end product is achieved compared to the primers used in conventional digital printing, which are based on aqueous solution.
- the primer based on an organic solvent is a two-component primer.
- the two components can be, for example, a two-component primer based on polyurethane and isocyanate according to one embodiment. This can then achieve a good mechanical and thermal stability.
- the order of the solvent-based primer is carried out according to an embodiment on a separate system and not on the digital printing system. This allows the use of a solvent-based primer, which is not possible due to the lack of explosion protection in conventional digital printing systems.
- the roller primed in a separate unit may then be of different lengths until printing takes place. Due to the different long lying time of this primed role, which varies from one day to several months, exceptionally up to max. 2 years, the gossip (set off) or the migration varies in size. This can then lead to only a slight stability of the print image being achieved in the case of the direct application of ink to the primer, as provided in conventional printing processes.
- the digital printing then takes place on the pre-primed composite (multilayer laminate) or the film, but - preferably inline - before printing the primed side of the composite (multilayer laminate) or the film is processed via a corona pretreatment.
- This pre-treatment serves to clean the surface of the (thin) primer layer (005) of materials which have been deposited by imprinting or migration on the surface.
- the corona pretreatment takes place in accordance with its corona strength owing to the comparatively thin primer layer, which has a thickness of preferably 0.1 to 1 g / m.sup.2.
- the corona strength is according to one embodiment in a range of 3 to 20 W min / m2.
- the digital printing then takes place on this corona-pretreated side (006) of the primer.
- a protective coating against physical, thermal or chemical influences is then applied for the actual application of the composite (multilayer laminate) or the film.
- a protective coating is applied to the digitally printed composite (multilayer laminate) or the film.
- the application rate of this protective coating is according to one embodiment 0.3 to 2 g / m 2 dry.
- the amount applied to the protective varnish may vary depending on the application of the film / composite and the amount of ink application. Preferably, a larger amount of protective lacquer is applied at a higher paint application.
- the digital-printed side of the composite (multilayer laminate) or film is processed in accordance with an embodiment to achieve a better resist adhesion on the digital-printed side - preferably inline - before the protective coating application with a corona pretreatment.
- This pretreatment is to clean the surface of the digital-printed side of the composite (multilayer laminate) or film which has been deposited by set-off or migration to surface.
- an organic solvent-based resist is used.
- the order of the solvent-based protective coating (009) can be made on a separate system or inline on the digital printing system.
- a radiation-curing protective lacquer may be used. This can according to one embodiment by means of a Elektrobeamers be cured. According to another embodiment by means of UV curing.
- an HP Indigo type printing machine is used for digital printing. Since this is not explosion-proof and thus not suitable for use of a primer based on an organic solvent, priming is preferably carried out on a separate unit.
- the printing of a film composite in the external printing is done with digital printing, so that the further steps such as laminating omitted, which are necessary for internal pressure.
- an organic solvent-based primer which improves the stability of the pressure.
- a corona pre-treatment is carried out both before the priming and before the printing and before the application of the protective lacquer.
- corona pre-treatment of the primed layer prior to printing with digital printing preferably also corona pre-treatment of the digitally printed surface prior to application of protective lacquer, increases the stability of the printed image and in particular one sufficient mechanical, thermal and chemical stability is achieved for sealable films. It is therefore particularly advantageous if a corona pre-treatment takes place both before the priming and before the digital printing and also before the application of protective lacquer.
- the primer is an organic solvent-based primer, preferably a two-component primer.
- printing is also done with an HP Indigo type machine.
- FIG. 1 schematically illustrates the process according to a preferred embodiment.
- the multi-layer composite (001) has a pressure side (003) and a sealing side (002).
- Such a printing process can be used to produce a printed composite which meets the particular chemical, thermal and mechanical stability requirements for sealable composites.
- the invention comprises a film produced by a process according to the invention or a film composite which has been corona-treated prior to the priming, before the digital printing and before the application of the protective lacquer.
- the invention also includes a device, each comprising modules for performing the method steps according to an embodiment of the invention.
