Description

FEUILLE D'EMBALLAGE POUR ROUTAGE PACKAGING SHEET FOR ROUTING
La présente invention se rapporte à une feuille d'emballage pour routage, donc destiné à l'emballage mécanisé de documents (revues, catalogues...), trié automatiquement et distribué par voie postale.The present invention relates to a packaging sheet for routing, therefore intended for the mechanized packaging of documents (magazines, catalogs, etc.), sorted automatically and distributed by post.
Il existe actuellement deux types d'emballage, les films plastiques et les enveloppes en papier.There are currently two types of packaging, plastic films and paper envelopes.
Les films plastiques, du a t de leur transparence, ne permettent pas de faire des envois à caractère confidentielPlastic films, due to their transparency, do not allow confidential shipments
Par ailleurs leur transparence gêne le tri postal automatique. En effet ce tri s'effectuant par lecture optique de l'adresse du destinataire située sur la revue, et donc sous le film plastique, la lecture est perturbée, d'une part par la réflectance de lumière que produit le film plastique et, d'autre part par les impressions portées sur le document emballé qui sont détectées à travers le film Pour éviter ce problème, il faudrait placer une étiquette d'adressage sur le film mais une telle opération est difficile à automatiser. Un autre inconvénient est la plissabilité des films qui gêne le cheminement des paquets sur les machines de tri.Furthermore, their transparency hinders automatic postal sorting. In fact, this sorting being carried out by optical reading of the recipient's address located on the magazine, and therefore under the plastic film, the reading is disturbed, on the one hand by the reflectance of light produced by the plastic film and, d on the other hand by the impressions carried on the wrapped document which are detected through the film To avoid this problem, an address label should be placed on the film, but such an operation is difficult to automate. Another drawback is the pliability of the films which hinders the movement of the packages on the sorting machines.
Un autre inconvénient des films plastiques est leur mauvaise imprimabilité ; ils ne peuvent pas être imprimés par toute technique d'impression.Another disadvantage of plastic films is their poor printability; they cannot be printed by any printing technique.
En outre, de part la nature de leur composition, ils ne sont pas biodégradables.In addition, due to the nature of their composition, they are not biodegradable.
Les enveloppes en papier ne possèdent pas ces inconvénients cependant elles ne permettent pas d'avoir des cadences d'emballage aussi rapides que celles avec des films plastiques : pour les films plastiques, la cadence d'emballage est environ 2 à 5 fois plus rapide que pour les enveloppes. Ceci s'explique par la nécessité de pliage complexe et de cachetage des enveloppes.Paper envelopes do not have these drawbacks, however, they do not allow packaging rates to be as rapid as those with plastic films: for plastic films, the packaging rate is approximately 2 to 5 times faster than for envelopes. This is explained by the need for complex folding and sealing of the envelopes.
La demanderesse se propose de fournir un emballage de routage qui ne présente pas les inconvénients des emballages actuels, à savoir de fournir un emballage qui permette tout particulièrement d'avoir à la fois des cadences élevées d'emballage mécanisé et un tri postal par lecture optique non perturbé. La demanderesse a trouvé qu'une telle feuille d'emballage pour routage peut être obtenue à partir d'un support en papier opaque, inφrimable, autoscellable au moyen d'un adhésif de scellage à froid, présent au moins partiellement sur la face interne dudit support.The Applicant intends to provide routing packaging which does not have the disadvantages of current packaging, namely to provide packaging which makes it possible in particular to have both high rates of mechanized packaging and postal sorting by optical reading. undisturbed. The Applicant has found that such a packaging sheet for routing can be obtained from an opaque paper support, inφrimable, autoscellable by means of a cold sealing adhesive, present at least partially on the internal face of said support.
Le support papier est constitué de fibres qui sont totalement ou majoritairement des fibres de cellulose, de charges, en particulier de charges opacifiantes (comme par exemple le dioxyde de titane, le carbonate de calcium précipité, le kaolin calciné) et d'additifs papetiers tels que liants, agents de rétention ou de floculation, agents de résistance humide, agents de collage en masse, agents antimousse. Il peut comporter aussi des bactéricides et des colorants.The paper support consists of fibers which are wholly or mainly cellulose fibers, fillers, in particular opacifying fillers (such as for example titanium dioxide, precipitated calcium carbonate, calcined kaolin) and papermaking additives such as as binders, retention or flocculation agents, wet strength agents, mass bonding agents, defoaming agents. It may also contain bactericides and dyes.
Le support peut être obtenu aussi à partir de vieux papiers ou de fibres recyclées.The support can also be obtained from old paper or recycled fibers.
On peut le traiter en presse encolleuse par des liants ou agents de renforcement comme l'amidon, l'alcool polyvinyfique ou par des agents de collage de surface.It can be treated in a size press with binders or reinforcing agents such as starch, polyvinyl alcohol or with surface bonding agents.
De préférence, le support papier est nuancé ou coloré, ceci lui confère une meilleure opacité. Le papier peut être coloré en masse et/ou sur une ou deux de ses faces.Preferably, the paper support is nuanced or colored, this gives it better opacity. The paper can be colored en masse and / or on one or two of its faces.
L'adhésif de scellage à froid est de préférence à base de caoutchouc naturel (polyisoprène) car celui- ci a la particularité de ne se sceller que sur lui-même. H n'est donc pas nécessaire de traiter l'autre face (non enduite avec l'adhésif) de la feuille pour pouvoir bobiner la feuille et la manipuler aisément.The cold sealing adhesive is preferably based on natural rubber (polyisoprene) because it has the particularity of only sealing on itself. It is therefore not necessary to treat the other side (not coated with the adhesive) of the sheet in order to be able to wind the sheet and handle it easily.
On peut cependant utiliser d'autres adhésifs scellables à froid (appelés COLD SEAL), utilisables en milieu aqueux ou en milieu solvant et si nécessaire traiter la face de la feuille ne comportant pas d'adhésif pour la rendre anti-adhérente par exemple par application de produits siliconés anti¬ adhérents.It is however possible to use other cold-sealable adhesives (called COLD SEAL), usable in an aqueous medium or in a solvent medium and if necessary treat the face of the sheet without adhesive to make it non-stick, for example by application non-stick silicone products.
De préférence, la pression linéaire pour sceller la feuille sur elle-même est supérieure ou égale à 50 N/cm. De préférence l'adhésif est coloré ; ced permet de renforcer l'opacité de la feuille d'emballage et donc de diminuer le grammage de la feuille ; ainsi on peut réaliser une économie sur l'affranchissement postal qui se ait en fonction du poids du paquet à expédier.Preferably, the linear pressure to seal the sheet on itself is greater than or equal to 50 N / cm. Preferably the adhesive is colored; ced strengthens the opacity of the packaging sheet and therefore reduces the grammage of the sheet; thus we can save on postage depending on the weight of the package to be shipped.
De préférence l'opacité de la feuille d'emballage, mesurée selon la norme ISO 2471, est supérieure ou égale à 75.Preferably the opacity of the packaging sheet, measured according to ISO 2471, is greater than or equal to 75.
L'adhésif est déposé soit de façon à recouvrir entièrement la face interne du support soit à ne couvrir que partiellement cette face et ce tout en permettant que l'emballage soit scellable sur lui-même.The adhesive is deposited either so as to completely cover the internal face of the support or to only partially cover this face and this while allowing the packaging to be sealable on itself.
Le dépôt d'adhésif peut être fait par tout moyen d'enduction connu. On peut par exemple le faire au moyen d'une coucheuse à lame d'air, d'une coucheuse à barre de type CHAMPION (voir Pulp and Paper, vol. IV, 3ème édition, pages 2152-2154) ou par héliogravure.The deposition of adhesive can be done by any known coating means. This can for example be done using an air knife coater, a CHAMPION bar coater (see Pulp and Paper, vol. IV, 3rd edition, pages 2152-2154) or by gravure printing.
Par exemple on peut déposer l'adhésif sur le pourtour de la feuille d'emballage, la feuille étant scellée par application des zones adhésivées se trouvant en regard selon une ligne de pliage ou la feuille est découpée autour de la revue à emballer et scellée sur tout son pourtour (sur les quatre bords).For example, the adhesive can be deposited on the periphery of the packaging sheet, the sheet being sealed by application of the adhesive areas located opposite along a fold line or the sheet is cut around the magazine to be packaged and sealed on all around (on all four edges).
On peut aussi par exemple déposer l'adhésif selon un dessin représentant des grilles entrecroisées ; ce dépôt est fait généralement par impression héliogravure ; la feuille peut être scellée sur elle- même.It is also possible, for example, to deposit the adhesive according to a drawing representing intersecting grids; this deposit is generally made by gravure printing; the sheet can be sealed on itself.
Les enductions totale ou en grille du support laissent une grande liberté d'utilisation des feuilles d'emballage, elles n'imposent pas de contrainte de découpe et de pliage minutieux, elles sont indépendantes du format des documents à expédier.The total coatings or grid of the support leave a great freedom of use of the packaging sheets, they do not impose any constraint of cutting and meticulous folding, they are independent of the format of the documents to be sent.
Pour éviter que l'emballage s'ouvre lors de sa manipulation ou de la distribution postale, il est préférable que la force de scellage (force à exercer pour ouvrir l'emballage) soit au moins égale à 1To prevent the packaging from opening during handling or postal delivery, it is preferable that the sealing force (force to be used to open the packaging) is at least equal to 1
N/cm.N / cm.
De préférence la face de la feuille qui ne comporte pas d'adhésif (face externe) a un niveau de collage élevé, le collage COBB mesuré selon la norme ISO 535, est inférieur à 25 g/m2. Ce collage donne à l'emballage une résistance élevée aux conditions climatiques humides auxquelles peut être soumis le paquet lors de son acheminement postal ; en effet, il peut être soumis à une forte humidité ou à la pluie lors de sa distribution dans les boites à lettre. Ainsi il ne sera pas abîmé et son contenu sera protégé.Preferably, the face of the sheet which does not have any adhesive (external face) has a high level of bonding, the COBB bonding measured according to standard ISO 535, is less than 25 g / m 2 . This bonding gives the packaging a high resistance to humid climatic conditions to which the package may be subjected during its postal delivery; indeed, it can be subjected to high humidity or rain during its distribution in letter boxes. Thus it will not be damaged and its content will be protected.
La présence de l'adhésif de scellage à froid ne gêne pas l'impression de la face externe (qui ne comporte pas d'adhésif) quelle que soit la technique d'impression (héliogravure, flexographie, offset, typographie, jet d'encre).The presence of the cold sealing adhesive does not interfere with the printing of the external face (which does not include any adhesive) whatever the printing technique (rotogravure, flexography, offset, typography, inkjet ).
L'emballage pourra comporter une fenêtre transparente pour pouvoir lire l'adresse si elle est portée sur la revue emballée.The packaging may include a transparent window so that the address can be read if it is included on the packaged magazine.
L'invention sera mieux comprise à l'aide des exemples non limitatifs suivants :The invention will be better understood using the following nonlimiting examples:
EXEMPLE 1EXAMPLE 1
On fabrique par voie humide sur machine à papier à table plate, un support papier à partir de la composition suivante, les parts étant exprimées en poids sec :A paper support is produced by wet process on a flat table paper machine from the following composition, the parts being expressed in dry weight:
- 100 parts de fibres de cellulose- 100 parts of cellulose fibers
- 18 parts de charges opacifiantes (dioxyde de titane, carbonate de calcium précipité)- 18 parts of opacifying fillers (titanium dioxide, precipitated calcium carbonate)
- 16,5 parts d'extendeur du dioxyde de titane- 16.5 parts of titanium dioxide extender
- 5,5 parts d'agent de renforcement (amidon, alroolpolyvinyïïque)- 5.5 parts of reinforcing agent (starch, alroolpolyvinyïïque)
- 0,3 part d'agent de collage (dimère d'alkyl cétène) - 0, 1 part d'agent de rétention- 0.3 part of sizing agent (alkyl ketene dimer) - 0.1 part of retention agent
- 0,05 part de colorant de nuançage noir.- 0.05 part of black shading dye.
La feuille obtenue est ensuite traitée en presse encolleuse par un mélange de liants (amidon et alcool polyvinylique), la reprise de cette composition en sec est de 2,5 g/m2.The sheet obtained is then treated in a size press with a mixture of binders (starch and polyvinyl alcohol), the recovery of this composition in dryness is 2.5 g / m 2 .
On dépose par couchage à l'aide d'une barre Champion l'adhésif scellable à froid qui est à base de caoutchouc naturel à raison de 1,8 g/m2 en sec. La feuille finie a un grammage de 60 g/m2. La feuille finie a une opacité de 90, mesurée selon la norme ISO 2471.The cold-sealable adhesive, which is based on natural rubber, is deposited by coating with a Champion bar at a rate of 1.8 g / m 2 dry. The finished sheet has a basis weight of 60 g / m 2 . The finished sheet has an opacity of 90, measured according to ISO 2471.
Le collage COBB mesuré selon la norme ISO 535 (eau, 1 minute, 23°C) est de 20 g/m2, pour la face imprimable (non recouverte d'adhésif).The COBB bonding measured according to ISO 535 standard (water, 1 minute, 23 ° C) is 20 g / m 2 , for the printable side (not covered with adhesive).
La feuille peut être imprimée avant ou après l'enduction d'adhésif par héhogravure ou par flexographie sans difficulté.The sheet can be printed before or after coating with adhesive by gravure or flexography without difficulty.
La feuille est utilisée sur une machine d'emballage automatisé pour emballer des revues ; la feuille est coupée, pliée autour de la revue et scellée sous une pression linéaire de 50 N/cm sur deux ou trois bords. La cadence d'emballage est de 5500 revues par heure, soit une cadence presque aussi élevée qu'en utilisant des films plastiques pour lesquels elle est de 5800 revues par heure.The sheet is used on an automated packaging machine to package magazines; the sheet is cut, folded around the magazine and sealed under a linear pressure of 50 N / cm on two or three edges. The packaging rate is 5500 reviews per hour, which is almost as high as using plastic films for which it is 5800 reviews per hour.
La force moyenne de scellage pour séparer deux feuilles en regard scellées sous une pression linéaire de 50 N/cm vaut 1,16 N/cm-The average sealing force to separate two facing sheets sealed under a linear pressure of 50 N / cm is 1.16 N / cm-
Sur les machines de tri postal par lecture optique, il n'y a pas de problème de lecture et les paquets sont facilement manipulables.On postal sorting machines by optical reading, there is no reading problem and the packages are easy to handle.
De plus le papier ayant un bon collage, il est résistant aux conditions climatiques humides auxquelles il peut être soumis lors de l'acheminement postalIn addition, the paper having a good bonding, it is resistant to the humid climatic conditions to which it can be subjected during the postal delivery.
EXEMPLE 2EXAMPLE 2
On fabrique une feuille comme dans l'exemple 1 mais avec un grammage plus faible et on a ajouté à l'adhésif scellable à froid un mélange de colorant noir et de pigments colorés bleu turquoise.A sheet is made as in Example 1 but with a lower grammage and a mixture of black dye and turquoise blue colored pigments has been added to the cold-sealable adhesive.
La composition adhésif-colorants est déposée en sec à raison de 4 g/m2.The adhesive-dye composition is deposited dry at the rate of 4 g / m 2 .
Le grammage de la feuille finie est de 54 g/m2.The grammage of the finished sheet is 54 g / m 2 .
La feuille a une opacité de 90, donc de même niveau que celle de la feuille de l'exemple 1, bien que le grammage soit plus faible. Le collage COBB de la face inφrimable est de 20 g/m2.The sheet has an opacity of 90, therefore of the same level as that of the sheet of Example 1, although the grammage is lower. The COBB bonding of the inφrimable face is 20 g / m 2 .
La force moyenne de scellage est id de 1,87 N/cm. On observe les mêmes avantages que pour l'exemple 1.The average sealing force is id of 1.87 N / cm. The same advantages are observed as for example 1.
Méthode de détermination de la force de scellage :Method of determining the sealing force:
On découpe 6 bandes de 5 x 10 cm du papier à tester, trois dans le sens marche, trois dans le sens travers.6 strips of 5 x 10 cm are cut from the test paper, three in the running direction, three in the cross direction.
On scelle chaque bande sur elle-même, on apphque une pression linéaire de 50 N/cm sur la bande en la faisant passer dans une calandre.Each strip is sealed on itself, a linear pressure of 50 N / cm is applied to the strip by passing it through a calender.
On mesure la force de scellage, c'est-à-dire la force qu'il faut exercer pour séparer les deux parties en regard, à l'aide d'un dynamomètre muni d'un enregistreur, la vitesse de la traverse étant de 200 mm/rnin.The sealing force is measured, that is to say the force that must be exerted to separate the two facing parts, using a dynamometer fitted with a recorder, the speed of the cross member being 200 mm / min.
On Êώ la moyenne entre le minimum et le maximum enregistrés et on obtient la force de scellage exprimée en cN/5 cm. On obtient la force moyenne de scellage en faisant la moyenne des forces mesurées (pour les sens marche et les sens travers). The average between the minimum and the maximum recorded is obtained and the sealing force expressed in cN / 5 cm is obtained. The average sealing force is obtained by averaging the measured forces (for the forward and cross directions).
