Abstract

A paper for a label which has an uncoated basic paper substrate on a verso side of which there is applied at least one coat of a liquid polymer, into which is incorporated one of an opacifier and an opacifying filler, intended to give product opacity in a dry state and in a wet state, adding to the opacity of the uncoated basic paper substrate so as to create a coat that is opaque and limits the ingress of water, between a product that is to be labeled and the uncoated basic paper substrate for use of the product in a wet environment or that is to be immersed in water, while at the same time preserving the qualities of the label.

Description

La présente invention se situe dans le domaine de la fabrication du papier, et plus précisément celle du papier non couché, en vu de réaliser des étiquettes présentant sur leur recto des informations souhaitées et destinées à être apposées sur tout support.The present invention is in the field of papermaking, and more specifically that of uncoated paper, in view of making labels having on their front desired information and intended to be affixed to any support.

Il pourra s'agir de tout type de conditionnement, mais le domaine plus particulièrement visé est celui des bouteilles destinées aux vins ou aux spiritueux, susceptibles par leur nature d'être stockées en milieu humide, tel que le réfrigérateur, le seau à glace ou tout autre procédé de stockage, conservation ou présentation destiné par exemple à les rafraîchir et les maintenir à une température adéquate.It may be any type of packaging, but the area particularly targeted is that of bottles for wines or spirits, likely by their nature to be stored in a humid environment, such as the refrigerator, ice bucket or any other method of storage, preservation or presentation intended for example to refresh them and maintain them at an adequate temperature.

Dans ce domaine particulier, force a été de constater que le contact du verso de l'étiquette sur la bouteille, par l'intermédiaire d'une colle, n'était pas suffisant pour conserver à l'étiquette son aspect d'origine, lorsqu'elle était soumise à l'humidité, notamment lors de l'immersion dans l'eau.In this particular field, it has been found that the contact of the back of the label on the bottle, by means of an adhesive, was not sufficient to preserve the original appearance of the label, when it was exposed to moisture, especially when immersed in water.

Or, les supports d'impression, notamment ceux à fortes blancheur et opacité connaissent une croissance soutenue, et cette demande émergente requiert l'apport de nouvelles solutions.However, print media, especially those with high whiteness and opacity are experiencing sustained growth, and this emerging demand requires the provision of new solutions.

En effet, il est difficile, à l'heure actuelle, de tenir tous les critères de qualité requis pour une étiquette de bonne tenue, qui sont les suivants :

  • les papiers blancs doivent conserver une blancheur intense pour des raisons d'esthétique,
  • ils doivent présenter une opacité renforcée en milieu sec et humide,
  • l'étiquette doit conserver après passage en milieu humide son aspect d'origine,
  • les papiers doivent résister à l'eau, d'un seau à glace par exemple.
Indeed, it is difficult, at the present time, to meet all the quality criteria required for a good-looking label, which are as follows:
  • white papers must maintain an intense whiteness for aesthetic reasons,
  • they must have enhanced opacity in a dry and wet environment,
  • the label must retain, after passage in a humid environment, its original appearance,
  • the papers must withstand water, for example an ice bucket.

Il est donc souhaitable que l'étiquette garde toujours une bonne opacité, quel que soit le milieu où elle se trouve (air ou eau), ce qui n'est pas toujours le cas actuellement.It is therefore desirable that the label always has good opacity, regardless of the environment (air or water), which is not always the case today.

Un autre problème réside dans le fait qu'au contact de l'eau, il se produit des infiltrations sous le papier, provoquant l'apparition de bulles d'air, qui se traduit par une inesthétique certaine.Another problem lies in the fact that in contact with water, there is infiltration under the paper, causing the appearance of air bubbles, which results in a certain unsightly.

A ce jour, les étiquettes sur le marché ne répondent pas de manière satisfaisante aux quatre critères évoqués ci-dessus. On obtient relativement fréquemment blancheur et opacité sèche, mais la résistance à l'eau et l'opacité humide ne sont pas suffisantes lorsque l'immersion est longue, par exemple au moins une heure pour ce qui est des passages dits au « seau à glace ».To date, the labels on the market do not respond satisfactorily to the four criteria mentioned above. Whiteness and dry opacity are relatively frequently obtained, but the water resistance and the wet opacity are not sufficient when the immersion is long, for example at least one hour for so-called "ice bucket" passages. ".

La présente invention a pour but de remédier à ces inconvénients et de respecter les critères de qualité précités. A cet effet, elle concerne un papier pour étiquette, caractérisé en ce qu'il est constitué d'un support papier de base non couché sur le verso duquel est appliqué, par tout moyen, au moins une couche d'un polymère liquide, dans lequel est incorporé un agent ou charge opacifiant, destiné à conférer audit produit une opacité sèche et humide, s'ajoutant à celle du support papier de base non couché, de manière à réaliser une couche opaque et limitant le passage de l'eau, entre le produit à étiqueter et le support papier de base non couché, pour une utilisation du produit en milieu humide ou devant être immergé dans l'eau, tout en préservant les qualités de l'étiquette.The object of the present invention is to remedy these drawbacks and to respect the quality criteria. supra. For this purpose, it relates to a label paper, characterized in that it consists of an uncoated base paper support on the back of which is applied, by any means, at least one layer of a liquid polymer, in which is incorporated an opacifying agent or filler, intended to impart to said product a dry and wet opacity, in addition to that of the uncoated base paper support, so as to produce an opaque layer and limiting the passage of water, between the product to be labeled and the uncoated base paper medium, for use in a moist environment or to be immersed in water, while preserving the qualities of the label.

On obtient ainsi une couche limitant la propagation de l'humidité entre le papier et le support.This gives a layer limiting the propagation of moisture between the paper and the support.

Cette couche pourra être déposée hors ligne de fabrication du papier ou encore en ligne.This layer can be filed off-line papermaking or online.

Bien entendu, hormis le marché des bouteilles évoqué, ce type d'étiquettes selon l'invention pourra être étendu à tout type d'application où un gain d'opacité humide et un maintien de l'apparence du papier présentent de l'importance.Of course, apart from the evoked bottles market, this type of label according to the invention can be extended to any type of application where a gain in wet opacity and a maintenance of the appearance of the paper are of importance.

L'invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

Cette description donnée à titre d'exemple non limitatif, fera mieux comprendre comment l'invention peut être réalisée en référence aux dessins annexés sur lesquels :

  • La figure unique représente schématiquement, en coupe transversale et à échelle agrandie, une étiquette selon l'invention, apposée sur une bouteille par exemple.
This description given by way of non-limiting example, will better understand how the invention can be made with reference to the accompanying drawings in which:
  • The single figure shows schematically, in cross section and on an enlarged scale, a label according to the invention, affixed to a bottle for example.

L'étiquette 1 désignée globalement sur la figure est obtenue à partir d'un papier non couché, c'est-à-dire qui n'a pas reçu, sur son recto, une couche de surface tendant à modifier son aspect.The label 1 indicated overall in the figure is obtained from uncoated paper, that is to say which has not received, on its front, a surface layer tending to change its appearance.

Dans tous les cas, l'étiquette 1 est destinée à recevoir sur son recto des informations, pour être apposée ensuite sur un support quelconque 6, notamment une bouteille en verre.In all cases, the label 1 is intended to receive on its front information, to be affixed thereafter on any support 6, including a glass bottle.

Selon l'invention, le papier pour étiquette est constitué d'un support papier de base non couché sur le verso duquel est appliqué, par tout moyen, au moins une couche d'un polymère liquide, dans lequel est incorporé un agent ou charge opacifiant, destiné à conférer audit produit une opacité sèche et humide, s'ajoutant à celle du support papier de base non couché, de manière à réaliser une couche opaque et limitant le passage de l'eau, entre le produit à étiqueter et le support papier de base non couché, pour une utilisation du produit en milieu humide ou devant être immergé dans l'eau, tout en préservant les qualités de l'étiquette, c'est-à-dire aspect initial (notamment blancheur et opacité) et résistance à l'eau.According to the invention, the label paper consists of an uncoated base paper backing on which is applied, by any means, at least one layer of a liquid polymer, in which an opacifying agent or filler is incorporated. , intended to confer on said product a dry and wet opacity, in addition to that of the uncoated base paper support, so as to produce an opaque layer and limiting the passage of water, between the product to be labeled and the paper support uncoated base, for use of the product in a humid environment or to be immersed in water, while preserving the qualities of the label, that is to say initial appearance (especially whiteness and opacity) and resistance to the water.

Le polymère liquide appliqué sur son verso possède des propriétés de liant.The liquid polymer applied on its back has binder properties.

Le polymère liquide utilisé pourra être un latex base aqueuse ou encore un latex base solvant.The liquid polymer used may be an aqueous base latex or a solvent base latex.

Avantageusement, le polymère liquide, est appliqué sur le verso de l'étiquette par enduction ou par pulvérisation.Advantageously, the liquid polymer is applied to the back of the label by coating or spraying.

Selon une autre caractéristique de l'invention, dans le produit polymère liquide, est incorporé un agent ou charge opacifiant, destiné à conférer audit produit une opacité sèche ou humide, s'ajoutant à celle du support papier non couché 2.According to another characteristic of the invention, in the liquid polymer product is incorporated an opacifying agent or filler, intended to impart to said product a dry or moist opacity, adding to that of the uncoated paper support 2.

Préférentiellement, l'agent opacifiant incorporé au polymère liquide est un titane, de manière à conférer audit produit une blancheur et une opacité intenses, s'ajoutant à celles du support papier.Preferably, the opacifying agent incorporated in the liquid polymer is a titanium, so as to impart to said product an intense whiteness and opacity, in addition to those of the paper support.

A l'heure actuelle, le titane est le produit du marché le plus opaque.At the moment, titanium is the most opaque product of the market.

Bien entendu, il pourrait être remplacé par du kaolin, du talc, du carbonate ou encore des substituants au titane.Of course, it could be replaced by kaolin, talc, carbonate or titanium substituents.

Selon la blancheur et l'opacité sèche et humide à obtenir, le papier recevra sur son verso une ou deux couches 3, 4 de polymère liquide.According to the whiteness and the dry and wet opacity to obtain, the paper will receive on its back one or two layers 3, 4 of liquid polymer.

Dans ce second cas, la dépose de la couche est soit réalisée en une fois 3+4, soit en deux fois, la première couche 3 de produit polymère étant chargée de titane pour assurer sa blancheur et son opacité, la seconde couche 4, avec ou sans titane, permettant de limiter le passage de l'eau au travers du papier 2.In this second case, the deposition of the layer is either carried out once in 3 + 4 or twice, the first layer 3 of polymer product being loaded with titanium to ensure its whiteness and opacity, the second layer 4 with or without titanium, to limit the passage of water through the paper 2.

Selon un perfectionnement de l'invention, un polymère liquide d'un type différent est ajouté en masse au cours de la fabrication du support papier de base non couché, de manière à augmenter la résistance à la rupture du papier lorsque celui-ci est soumis à un milieu aqueux.According to an improvement of the invention, a liquid polymer of a different type is added in bulk during the manufacture of the uncoated base paper support, so as to increase the breaking strength of the paper when it is submitted to an aqueous medium.

Préférentiellement, le polymère liquide est de nature épichlohydrine.Preferably, the liquid polymer is of epichlorohydrin nature.

Enfin, le support papier de base non couché 2 préalablement enduit 3, 4 reçoit ultérieurement une colle 5 déposée au verso par tout moyen sur la/les couches polymères.Finally, the uncoated base paper support 2 previously coated 3, 4 subsequently receives an adhesive 5 deposited on the back by any means on the / the polymer layers.

La fabrication d'une étiquette 1 à partir d'un papier tel qu'il vient d'être décrit comporte les étapes suivantes :

  • choix de la qualité du support papier de base non couché 2, en fonction de son grammage, sa teinte et sa composition
  • enduction ou pulvérisation à froid du support papier de base non couché 2 sur son verso, par un polymère liquide 3, 4 mélangé à un agent opacifiant, en vue de constituer une couche de blancheur et d'opacité intenses,
  • application éventuellement d'une seconde couche de polymère, mélangé ou non à un agent opacifiant déposé sur la première couche et permettant de limiter le passage de l'eau au travers du papier 2.
  • application d'une colle 5 sur la/les couches polymères 3, 4,
  • impression des étiquettes sur le recto du papier 1,
  • découpage des étiquettes 1,
  • application par tout moyen de l'étiquette 1 sur un support 6.
The manufacture of a label 1 from a paper as just described comprises the following steps:
  • choice of the quality of the uncoated base paper medium 2, depending on its grammage, hue and composition
  • coating or cold spraying the uncoated base paper support 2 on its back with a liquid polymer 3, 4 mixed with an opacifying agent, in to form a layer of intense whiteness and opacity,
  • optionally applying a second polymer layer, mixed or not with an opacifying agent deposited on the first layer and for limiting the passage of water through the paper 2.
  • applying an adhesive 5 to the polymer layer (s) 3, 4,
  • printing labels on the front side of the paper 1,
  • cutting the labels 1,
  • application by any means of the label 1 on a support 6.
