PROCEDE DE FABRICATION D'EMBALLAGES IMPRIMES A PARTIR DE DECOR PREDEFORMEPROCESS FOR PRODUCING PRINTED PACKAGES FROM PREFORMED DECOR
DOMAINE DE L'INVENTIONFIELD OF THE INVENTION
L'invention concerne le domaine des emballages décorés obtenus par mise en forme d'un support porteur d'un décor prédéformé.The invention relates to the field of decorated packaging obtained by shaping a support carrying a preformed decoration.
ETAT DE LA TECHNIQUESTATE OF THE ART
La décoration des emballages obtenus par mise en forme de matériau en bande ou en feuille est généralement réalisée selon deux voies principales:The decoration of the packaging obtained by shaping a strip or sheet material is generally carried out in two main ways:
- d'une part, dans le cas des boîtes boisson métalliques, une bande métallique est mise en forme par emboutissage et étirage, puis le corps de boîte obtenu est décoré, par exemple par un procédé offset. - d'autre part, dans le cas des boîtes de conserve, la bande métallique est généralement décorée par impression offset humide, et les formats décorés sont ensuite mis en forme par emboutissage. Dans ce cas, l'image imprimée est une image prédéformée, de manière à restituer, après mise en forme, l'image souhaitée, comme indiqué dans la demande européenne EP-A-0371897.- On the one hand, in the case of metal drink cans, a metal strip is shaped by stamping and drawing, then the box body obtained is decorated, for example by an offset process. - on the other hand, in the case of cans, the metal strip is generally decorated by wet offset printing, and the decorated formats are then shaped by stamping. In this case, the printed image is a preformed image, so as to restore, after shaping, the desired image, as indicated in European application EP-A-0371897.
PROBLEME POSE Le procédé selon l'état de la technique présente plusieurs inconvénients: d'une part, les feuilles de métal à décorer étant relativement épaisses, de l'ordre de 0,20 mm, l'impression de formats, et non de bande, en offset humide est, en pratique, seule mise en oeuvre industriellement, sur des lignes d'impression spécifiques, - d'autre part les encres offset nécessitent une cuisson à haute température et pendant un temps relativement long (plusieurs minutes vers 180°C par exemple). Il peut en outre être nécessaire d'effectuer une passe supplémentaire de survernissage pour protéger les encres contre les agressions physiques (rayure) ou physico-chimiques (action de l'eau ou de la vapeur dans un stérilisateur),PROBLEM POSED The process according to the state of the art has several drawbacks: on the one hand, the metal sheets to be decorated being relatively thick, of the order of 0.20 mm, the printing of formats, and not of tape , in wet offset is, in practice, only implemented industrially, on specific printing lines, - on the other hand offset inks require baking at high temperature and for a relatively long time (several minutes around 180 ° C for example). It may also be necessary to carry out an additional over-coating pass to protect the inks against physical (scratch) or physicochemical attack (action of water or steam in a sterilizer),
- enfin, le procédé selon l'état de la technique nécessite un volume très important d'en-cours de fabrication sous forme de métal imprimé spécifiquement, ce qui implique un financement de stock et donc des frais financiers non négligeables.- Finally, the process according to the state of the art requires a very large volume of work-in-progress in the form of specifically printed metal, which implies financing of stock and therefore significant financial costs.
DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION
Selon l'invention, le procédé de fabrication d'emballage imprimé par mise en forme d'un support porteur d'un décor prédéformé, est caractérisé en ce que, a) on imprime en décor inversé sur un film plastique F ledit décor D prédéformé avec des encres adhérentes audit film plastique, de manière à obtenir un film imprimé multicouches symbolisé par F/D sous forme de bobine, b) on assemble ledit support S et le film imprimé multicouches F/D, de manière à former un support imprimé F/D/S, le décor D étant pris en sandwich entre ledit film D et ledit support S, c) on met en forme ledit support imprimé F/D/S, de manière à obtenir un emballage imprimé.According to the invention, the method of manufacturing printed packaging by shaping a support carrying a pre-deformed decoration, is characterized in that, a) printing in reverse decoration on a plastic film F said pre-deformed decoration with inks adhering to said plastic film, so as to obtain a multilayer printed film symbolized by F / D in the form of a reel, b) assembling said support S and the multilayer printed film F / D, so as to form a printed support F / D / S, the decoration D being sandwiched between said film D and said support S, c) shaping said printed support F / D / S, so as to obtain a printed packaging.
L'invention concerne plus spécifiquement les emballages métalliques obtenus, selon l'état de la technique, par impression de bande métallique puis mise en forme de cette bande, typiquement par emboutissage.The invention relates more specifically to metal packaging obtained, according to the state of the art, by printing a metal strip and then shaping this strip, typically by stamping.
Mais elle s'applique aussi à des emballages en matière plastique.However, it also applies to plastic packaging.
L'invention, comme cela apparaît clairement sur les figures, modifie totalement la fabrication d'emballages, notamment métalliques, imprimés. En effet, d'une part, l'invention permet d'éviter le passage du matériau support en bande au matériau support en format. D'autre part, l'invention évite l'impression directe du support métallique, ce qui a deux conséquences avantageuses : * l'impression de support métallique est coûteuse en énergie étant donné qu'à chaque passe d'impression, il faut porter à haute température le support métallique lui-même. * par ailleurs, le stockage de support métallique imprimé est beaucoup plus coûteux en frais d'immobilisation que le stockage de film imprimé.The invention, as is clearly seen in the figures, completely modifies the manufacture of packaging, in particular metallic, printed. Indeed, on the one hand, the invention makes it possible to avoid the passage from the support material in strip to the support material in format. On the other hand, the invention avoids the direct printing of the metallic support, which has two advantageous consequences: * the printing of metallic support is costly in energy since at each printing pass, it is necessary to bring to high temperature the metal support itself. * moreover, the storage of printed metallic support is much more expensive in terms of capital costs than the storage of printed film.
Pour l'homme du métier, l'invention constitue sinon une révolution, du moins un changement radical particulièrement avantageux sur le plan des coûts de production.For a person skilled in the art, the invention constitutes, if not a revolution, at least a radical change which is particularly advantageous in terms of production costs.

DESCRIPTION DETAILLEE DE L'INVENTIONFigure 3 shows schematically the method according to the invention and illustrates the position of the decoration D, between the film F and the support S. DETAILED DESCRIPTION OF THE INVENTION
Selon l'invention, on assemble ledit support S et ledit film F en choisissant comme encre du décor D une encre thermoadhésive audit support S.According to the invention, said support S and said film F are assembled by choosing, as decoration ink D, a thermoadhesive ink to said support S.
Le support S peut être une bande ou une feuille métallique d'épaisseur supérieure à 50 μm, qui peut être en aluminium ou alliage d'aluminium, ou en acier. Le support S peut être aussi une bande ou une feuille de matière thermoplastique, qui peut être choisie parmi le PE,The support S can be a strip or a metal sheet with a thickness greater than 50 μm, which can be made of aluminum or aluminum alloy, or steel. The support S can also be a strip or a sheet of thermoplastic material, which can be chosen from PE,
PP, copolymères PE/PP, ou en PET.PP, PE / PP copolymers, or PET.
De préférence, le matériau support S est utilisé en bande ou bobine.Preferably, the support material S is used in strip or reel.
Le film F est en polyoléfine choisie parmi le PE, PP, copolymères PE/PP, ou en PET, en fonction des contraintes mécaniques et thermiques auxquelles il est soumis.The film F is made of polyolefin chosen from PE, PP, PE / PP copolymers, or PET, depending on the mechanical and thermal stresses to which it is subjected.
L'encre thermoadhésive audit support S est choisie de manière à ce que la thermoadhésion audit support ait lieu à une température située au moins à 20βC au-dessus de la température de séchage de l'encre sur ledit film F.The ink thermoadhesive to said support S is chosen so that the thermoadhesive to said support takes place at a temperature at least 20 β C above the drying temperature of the ink on said film F.
Selon l'invention, ladite encre est une encre comprenant une première résine assurant le séchage de l'encre et la possibilité d'obtenir un film imprimé F/D en bobine, et une seconde résine assurant au moins partiellement la fonction d'assemblage du film imprimé F/D audit support S par thermoscellage à une température supérieure à celle de séchage de l'encre sur ledit film.According to the invention, said ink is an ink comprising a first resin ensuring the drying of the ink and the possibility of obtaining an F / D printed film on a reel, and a second resin at least partially ensuring the assembly function of the film printed F / D on said support S by heat sealing at a temperature higher than that of drying of the ink on said film.
Selon une première modalité de l'invention, cette encre peut être une encre liquide à solvants pour héliogravure, ladite première résine étant à base de résines cellulosiques.According to a first embodiment of the invention, this ink can be a liquid ink with solvents for gravure printing, said first resin being based on cellulose resins.
Ces résines cellulosiques sont choisies de préférence parmi la nitrocellulose, l'acétopropionate de cellulose, 1'acétobutyrate de cellulose, l'éthylcellulose.These cellulosic resins are preferably chosen from nitrocellulose, cellulose acetopropionate, cellulose acetobutyrate, ethylcellulose.
Selon une seconde modalité de l'invention, ladite encre est une encre à séchage UV, ladite première résine comprenant des oligomères réticulables sous rayonnement UV.According to a second embodiment of the invention, said ink is a UV-drying ink, said first resin comprising oligomers crosslinkable under UV radiation.
Quand le support S est un support métallique, ladite seconde résine comprend des fonctions acide carboxylique permettant l'adhérence de ladite encre sur ledit support S.When the support S is a metallic support, said second resin comprises carboxylic acid functions allowing the adhesion of said ink on said support S.
Dans ce cas, ladite seconde résine est un copolymère ou un terpolymère comprenant des groupements carboxyliques.In this case, said second resin is a copolymer or a terpolymer comprising carboxylic groups.
Quand le support S est un support plastique, ladite seconde résine peut se confondre avec ladite première résine dans la mesure où celle-ci peut permettre d'une part, le séchage de l'encre déposée sur le film F, à température relativement basse, principalement par élimination de solvant, d'autre part, à plus haute température, le thermoscellage du film imprimé F/D sur le support S.When the support S is a plastic support, said second resin can be confused with said first resin insofar as the latter can allow on the one hand, the drying of the ink deposited on the film F, at relatively low temperature, mainly by elimination of solvent, on the other hand, at higher temperature, the heat sealing of the printed film F / D on the support S.
Dans le cas où les emballages obtenus selon l'invention doivent être traités thermiquement à température relativement haute, par exemple vers 130βC dans un autoclave de stérilisation, ladite encre comprend en outre un agent de reticulation de ladite première et/ou seconde résine, de manière à ce que ladite encre soit stérilisable.In the case where the packaging obtained according to the invention must be heat treated at a relatively high temperature, for example around 130 β C in a sterilization autoclave, said ink also comprises a crosslinking agent for said first and / or second resin, so that said ink is sterilizable.
ESSAI DE REALISATIONIMPLEMENTATION TEST
On a réalisé un décor inverse prédéformée sur film de PP de 30 μm d'épaisseur, par héliogravure.A preformed reverse decoration was produced on PP film 30 μm thick, by gravure printing.
Pour cela on utilisé des encres à solvants comprenant : * comme solvant, de l'acétate d'éthyleFor this, solvent inks are used comprising: * as solvent, ethyl acetate
* comme première résine, de la nitrocellulose, * comme seconde résine un copolymère styrène-acrylate avec fonctions carboxyliques,* as the first resin, nitrocellulose, * as a second resin, a styrene-acrylate copolymer with carboxylic functions,
* un durcisseur à fonctions isocyanate, destiné à rendre l'encre stérilisable a été ajouté.* a hardener with isocyanate functions, intended to make the ink sterilizable, has been added.
On a ainsi obtenu une bobine de film imprimé F/D. Ce film a été thermocollé vers 120βC sur bande d'aluminium de 0,23 mm d'épaisseur (alliage 5052 selon codification de l'Aluminum Association), comme support S, pour donner le matériau multicouches final S/D/F.This resulted in a reel of F / D printed film. This film was heat-sealed around 120 β C on a 0.23 mm thick aluminum strip (alloy 5052 according to the codification of the Aluminum Association), as support S, to give the final multilayer material S / D / F.
Ce matériau a été embouti pour donner des boîtes. Il n'a pas été noté de problème particulier durant la fabrication de ces boîtes ou durant le conditionnement et la stérilisation qui ont suivi.This material was stamped to give boxes. No particular problem was noted during the manufacture of these boxes or during the packaging and sterilization which followed.
AVANTAGES DE L'INVENTIONADVANTAGES OF THE INVENTION
L'avantage de l'invention est essentiellement d'ordre économique. Il a été estimé, dans le cas de la fabrication d'emballages métalliques imprimés, que le procédé selon l'invention permettait de diminuer les coûts de fabrication de 5 à 10 % selon notamment le niveau nécessaire des stocks de produits intermédiaires. En effet, dans le métier de l'emballage métallique et de la conserve en particulier, le délai peut être très court entre une commande des boîtes et leur livraison, compte tenu du fait que les quantités d'aliments à conditionner (légumes, poissons, etc..) dépend beaucoup de facteurs aléatoires, et en particulier de la météorologie. L'invention permet donc de stocker des bobines de film imprimé au lieu de stocker des piles de format métalliques imprimés, ce qui permet de réduire les délais de livraison, sans augmenter le stock des en-cours de formats métalliques, stock dont le financement est onéreux. The advantage of the invention is essentially economic. It has been estimated, in the case of the manufacture of printed metallic packaging, that the method according to the invention makes it possible to reduce the manufacturing costs by 5 to 10% depending in particular on the necessary level of stocks of intermediate products. Indeed, in the metal packaging and canning industry in particular, the time can be very short between an order for the boxes and their delivery, given the fact that the quantities of food to be packaged (vegetables, fish, etc.) depends a lot on random factors, and in particular on meteorology. The invention therefore makes it possible to store reels of printed film instead of storing stacks of printed metal format, which makes it possible to reduce delivery times, without increasing the stock of work in progress in metal formats, stock whose financing is expensive.
