SURFACE AU MOINS UNE SUBSTANCE IRIDESCENTE, PROCEDE POUR SA
FABRICATION, ET APPLICATION D'UN TEL MATERIAU DANS L'INDUSTRIE DE
L'EMBALLAGE
L'invention concerne un matériau obtenu par voie papetière, notassent une feuille de papier comportant au moins des fibres cellulosiques, ce matériau étant imprimable, résistant à la chaleur, et iuni en surface d'au moins une substance iridescente.PRINTABLE MATERIAL OBTAINED BY PAPER, COMPRISING
SURFACE OF AT LEAST ONE IRIDESCENT SUBSTANCE, METHOD FOR ITS
MANUFACTURE AND APPLICATION OF SUCH MATERIAL IN THE INDUSTRY
PACKAGING
The invention relates to a material obtained by the papermaking process, including a sheet of paper comprising at least cellulosic fibers, this material being printable, heat resistant, and provided on the surface with at least one iridescent substance.

L'invention concerne en outre le procédé de fabrication d'un tel matériau, un complexe carton ondulé avec ce natériau et l'application d'un tel matériau dans l'industrie de l'emballage.The invention further relates to the method of manufacturing such a material, a corrugated cardboard complex with this material and the application of such a material in the packaging industry.

On connait déjà des cartons ondulés qui sont réalisés en collant à chaud au soins une feuille de papier superficielle avec du carton ondulé qui sert à rigidifier l'ensemble Pour l'utilisation d'un tel complexe constitué de carton ondulé et de la feuille de papier superficielle, on iipriie la feuille de papier dans un but décoratif et/ou dans le but d'indiquer la qualité du produit contenu dans l'eiballage famé du carton. D'une maniée connue, ces complexes sont imprimés par flexographie.We already know of corrugated cardboard which is made by hot gluing with care a surface sheet of paper with corrugated cardboard which serves to stiffen the whole For the use of such a complex consisting of corrugated cardboard and the sheet of paper surface, Iipriie the sheet of paper for decorative purposes and / or in order to indicate the quality of the product contained in the famous packaging of the cardboard. In a known manner, these complexes are printed by flexography.

Plus récenent, on a voulu conférer à ces cartons pour emballage, qu'ils soient ondulés ou non, un aspect plus esthétique et on a désiré obtenir des teintes métallisés Malheureuseuent, les pigments métalliques ne tenaient pas toujours à la température et on était obligé d'imprimer le complexe ondulé après sa fabrication par un procédé flexographique. Dans ce cas, on a utilisé des encres d'iapression à base de pigments métalliques, l'impression étant effectuée directeuent sur le carton.Or, l'impression directe sur un carton revêtu d'un pigment métallique est peu conode et ne permet qu'une mauvaise impression postérieure par d'autres encres directement au-dessus de l'encre uetallique
L'invention vise à fournir un matériau comportant en surface une impression héliographique pseudo-métallisé, à savoir : donnant l'illusion d'une impression métallise et pouvant ensuite être imprimé par une encre habituelle. L'impression héliographique est de meilleure qualité que l'impression flexographique et permet une meilleure qualité de sur-impression ou repiquage d'impression.More recently, we wanted to give these boxes for packaging, whether corrugated or not, a more aesthetic appearance and we wanted to obtain metallic colors Unfortunately, the metallic pigments did not always hold to temperature and we were forced to '' print the corrugated complex after its manufacture by a flexographic process. In this case, printing inks based on metallic pigments were used, the printing being carried out directly on the cardboard, but direct printing on a cardboard coated with a metallic pigment is not very convenient and only allows '' a bad posterior impression by other inks directly above the uetallic ink
The invention aims to provide a material comprising on the surface a pseudo-metallized heliographic printing, namely: giving the illusion of a metallized printing and which can then be printed with a usual ink. Rotogravure printing is of better quality than flexographic printing and allows better quality of overprinting or printing out.

Un but de l'invention est aussi de fournir une feuille de papier revêtue sur toute sa surface d'une impression héliographique pseudo-métallisé et pouvant etre collée à chaud sur un carton ondulé.An object of the invention is also to provide a sheet of paper coated over its entire surface with a pseudo-metallized heliographic printing and which can be hot-glued onto corrugated cardboard.

Un autre but de l'invention est de fournir un procédé de préparation d'une feuille obtenue par voie papetière munie d'une impression pseudo métallisé, imprimable postérieurement et résistante à chaud.Another object of the invention is to provide a process for the preparation of a sheet obtained by the papermaking process provided with a pseudo metallized printing, posteriorly printable and heat resistant.

Or, on a découvert de manière surprenante qu'en effectuant à la surface d'une nappe fibreuse obtenue par voie papetière, une impression par héliogravure à l'aide d'une composition comportant au moins une substance iridescente, on obtient une impression résistante à chaud et qui permet une sur-impression par tout moyen, avec toute encre habituelle. La couche de substance iridescente peut être déposée de manière continue ou discontinue.Now, it has surprisingly been discovered that by carrying out on the surface of a fibrous sheet obtained by the papermaking process, a gravure printing using a composition comprising at least one iridescent substance, an impression resistant to hot and which allows an over-printing by any means, with any usual ink. The layer of iridescent substance can be deposited continuously or discontinuously.

On entend ici par substance iridescente, une substance qui, selon le principe de la diffraction de la lumière par des couches minces, provoque, en fonction de l'angle d'observation, des reflets dont les couleurs recouvrent tout ou partie le spectre arc-en-ciel de la lumière décomposée.The term iridescent substance is understood here to mean a substance which, according to the principle of diffraction of light by thin layers, causes, as a function of the angle of observation, reflections the colors of which cover all or part of the arc spectrum. rain of decomposed light.

Par substance iridescente pouvant entre utilisée selon l'invention, on peut citer les extraits de nacre (tels que les essences de nacre), les sels de plomb et les micas. Les substances préférées sont les micas, les extraits de nacre étant coûteux, et les sels de plomb étant toxiques, entrainent des règles d'hygiène et de sécurité très strictes au cours de la fabrication. By iridescent substance which can be used according to the invention, mention may be made of mother-of-pearl extracts (such as mother-of-pearl essences), lead salts and micas. The preferred substances are micas, mother-of-pearl extracts being expensive, and lead salts being toxic, entail very strict health and safety rules during manufacture.

Parmi les substances iridescentes qui conviennent, on préfère les micas enrobés avec au moins un oxyde métallique, et en particulier les produits conmercialisés par la société MERCK AG sous le nom de
IRIODINE, ces produits étant des micas enrobés d'oxyde de titane TiOo avec éventuellement au moins un autre oxyde métallique.Among the iridescent substances which are suitable, micas coated with at least one metal oxide are preferred, and in particular the products sold by the company MERCK AG under the name of
IRIODINE, these products being micas coated with titanium oxide TiOo with optionally at least one other metal oxide.

La différence d'épaisseur de la couche d'oxyde de titane et l'addition éventuelle d'un ou plusieurs autres oxydes métalliques donnent des produits ayant des nuances colorées différentes. Le procédé de préparation selon l'invention consiste à déposer au moins une substance iridescente à la surface ou dans la masse de la nappe fibreuse.The difference in thickness of the titanium oxide layer and the possible addition of one or more other metal oxides gives products having different colored shades. The preparation process according to the invention consists in depositing at least one iridescent substance on the surface or in the mass of the fibrous web.

La nappe fibreuse est avantageusement un produit obtenu par voie humide ou voie papetière et de préférence, constitué de fibres cellulosiques et éventuellement, de fibres minérales et/ou de charges.The fibrous web is advantageously a product obtained by the wet or papermaking process and preferably, consisting of cellulosic fibers and optionally, mineral fibers and / or fillers.

Le procédé préféré selon l'invention consiste à ispriser la surface d'un papier ou une partie de cette surface au moyen d'une encre comprenant une ou plusieurs substances iridescentes.The preferred method according to the invention consists in isprising the surface of a paper or a part of this surface by means of an ink comprising one or more iridescent substances.

Selon l'invention on utilise de préférence des encres qui comportent de 4 à 30 parties en poids de substances iridescentes et 70 à 96 parties en poids de liant, le total faisant 100 parties. On limite à 30 parties en poids si l'on veut obtenir une résistance au frottement à sec de la couche imprimée lors de l'utilisation finale du produit ou de son passage sur une onduleuse.According to the invention, inks are preferably used which comprise from 4 to 30 parts by weight of iridescent substances and 70 to 96 parts by weight of binder, the total making 100 parts. We limit to 30 parts by weight if we want to obtain a resistance to dry friction of the printed layer during the final use of the product or its passage on a corrugator.

On peut aussi appliquer la ou les substances iridescentes par couchage sur la nappe fibreuse ou le papier. Le bain de couchage est dépose sur une quantité de 5 à 10 g/m2 en poids sec. De préférence, le bain de couchage renferme de 10 à 30 parties en poids de substances iridescentes pour 70 à 90 parties en poids de liant ou vernis de couchage, le total faisant 100 parties. The iridescent substance or substances can also be applied by coating on the fibrous web or the paper. The coating bath is deposited on an amount of 5 to 10 g / m2 by dry weight. Preferably, the coating bath contains from 10 to 30 parts by weight of iridescent substances per 70 to 90 parts by weight of coating binder or varnish, the total making 100 parts.

D'autres avantages et caractéristiques de l'invention seront mieux compris à la lecture qui va suivre d'exemples de réalisation nullement limitatifs mais donnés à titre d'illustration.Other advantages and characteristics of the invention will be better understood on reading the following examples of embodiments which are in no way limitative but given by way of illustration.

Exemple 1
Préparation d'un carton d'emballage à aspect métallisé.Example 1
Preparation of a metallic-look packaging carton.

On utilise un papier Korfnaf (couché offset ou hélio) vendu par la société suédoise tORFNAF-MARMA ayant un grammage de 140 g/X2. Using Korfnaf paper (offset or rotogravure coated) sold by the Swedish company tORFNAF-MARMA having a grammage of 140 g / X2.

On effectue une impression par héliogravure sur ce papier à l'aide d'une composition d'encre contenant une substance iridescente et un liant, dont la composition est la suivante - vernis ou liant pour héliogravure 92 parties en poids - substance iridescente
IRIODINE 100-4670 de MERCI AG 8 parties en poids
La quantité de cette composition déposée est de l'ordre de 16 g/m2 (poids humide).A gravure printing is carried out on this paper using an ink composition containing an iridescent substance and a binder, the composition of which is as follows - varnish or binder for photogravure 92 parts by weight - iridescent substance
IRIODINE 100-4670 from MERCI AG 8 parts by weight
The amount of this deposited composition is of the order of 16 g / m2 (wet weight).

On obtient une feuille ayant un aspect métallisé.A sheet having a metallic appearance is obtained.

On colle sur une onduleuse à carton cette feuille avec un carton ondulé, à chaud, par exemple à une température comprise entre 150 et 1800C. We glue this sheet with a corrugated cardboard corrugator, hot, for example at a temperature between 150 and 1800C.

Le carton ainsi fabriqué est rigide et présente un aspect brillant métallisé uniforme. The cardboard thus produced is rigid and has a uniform metallic shiny appearance.

Exemple 2
On réalise l'impression au moyen de trois cylindres d'héliogravure. On effectue un premier passage avec le premier cylindre et une encre standard, on effectue un deuxième passage avec le deuxième cylindre et une autre encre standard, puis un troisième passage avec un troisième cylindre présentant un dessin décoratif, la composition de l'encre étant la suivante - vernis pour héliogravure 83 parties en poids - substance iridescente
IRIODINE COLIBRI 81006 17 parties en poids
On dépose ensuite par une impression quelconque des ensembles alpha-nuseriques à la fois sur les impressions standard et l'impression iridescente. On constate que l'impression iridescente peut être sur-imprimée conte les impressions standard. On colle à chaud, par exemple à 1600C, le papier ainsi imprimé sur une feuille de carton non ondulé pour réaliser notamment de petits emballages. Example 2
Printing is carried out using three gravure cylinders. A first pass is made with the first cylinder and a standard ink, a second pass is made with the second cylinder and another standard ink, then a third pass with a third cylinder having a decorative design, the composition of the ink being the next - photogravure varnish 83 parts by weight - iridescent substance
IRIODINE COLIBRI 81006 17 parts by weight
One deposits then by any impression of the alpha-nuseric sets at the same time on the standard impressions and the iridescent impression. It is noted that the iridescent print can be overprinted against standard prints. The paper thus printed is hot glued, for example at 1600 ° C., on a sheet of non-corrugated cardboard, in particular for making small packages.
