Abstract
Description
La présente invention concerne un matériau synthétique imprimable, notamment pour la fabrication d'articles en matière synthétique devant recevoir une impression, tels que des pochettes, des dossiers, des valisettes à usage publicitaire ou autres. The present invention relates to a printable synthetic material, in particular for the manufacture of articles made of synthetic material which must receive an impression, such as sleeves, files, bags for advertising or other use.
Les polyoléfines et particulièrement le polypropylène ont des qualités qui les rendent particulièrement bien adaptées à la fabrication d'articles tels que précités. Elles ont toutefois pour inconvénient important de ne pas être imprimables telles quelles dans de bonnes conditions. Polyolefins and particularly polypropylene have qualities which make them particularly well suited to the manufacture of articles as mentioned above. However, they have the significant drawback of not being printable as such under good conditions.
Il est connu de remédier à cet inconvénient en soumettant les feuilles de polyoléfine destinées à une telle application à un traitement CORONA. Ce traitement a malheureusement une efficacité qui décroît rapidement, impliquant une impression dans les deux ou trois mois qui suivent, ce qui constitue une contrainte pratique non négligeable. It is known to remedy this drawback by subjecting the polyolefin sheets intended for such an application to a CORONA treatment. This treatment unfortunately has an effectiveness which decreases rapidly, implying an impression in the two or three months which follow, which constitutes a considerable practical constraint.
Il est également connu de réaliser un matériau multicouches comprenant une couche de base en polypropylène et une couche imprimable constituée de fibres de cellulose, cette couche ayant ainsi sensiblement l'aspect et les caractéristiques du papier. It is also known to produce a multilayer material comprising a base layer of polypropylene and a printable layer made of cellulose fibers, this layer thus having substantially the appearance and characteristics of the paper.
Les deux couches sont réalisées séparément et sont ensuite assemblées par jonction ou enduction. The two layers are made separately and are then assembled by joining or coating.
Ce matériau a pour inconvénient d'être cher et complexe à fabriquer, étant donné qu'il ne peut être mis en oeuvre par des techniques telles que la coextrusion ou la technique dite "de plaxage à chaud". En outre, il n'est pas recyclable dans de très bonnes conditions. This material has the disadvantage of being expensive and complex to manufacture, since it cannot be used by techniques such as coextrusion or the technique known as "hot plaxing". In addition, it is not recyclable under very good conditions.
La présente invention vise à remédier à l'ensemble de ces inconvénients. The present invention aims to remedy all of these drawbacks.
Le matériau qu'elle concerne comprend une couche de base en polyoléfine et au moins une couche chargée, en polyoléfine pouvant être liée à la couche de base par coextrusion ou "plaxage à chaud", cette couche chargée présentant une proportion de 50 à 95 % de charge minérale ou organique. The material to which it relates comprises a base layer of polyolefin and at least one charged layer, of polyolefin which can be bonded to the base layer by coextrusion or "hot plaxing", this charged layer having a proportion of 50 to 95%. of mineral or organic filler.
La technique de coextrusion consiste à superposer, au moyen d'un ensemble dit "de répartition", différentes couches de polymères à l'intérieur même de la filière d'extrusion. The coextrusion technique consists of superimposing, by means of a so-called "distribution" assembly, different layers of polymers inside the extrusion die.
La technique dite "de plaxage à chaud" est celle consistant à réaliser, immédiatement à la sortie d'une filière d'extrusion, la jonction de la couche extrudée avec une couche de matériau préalablement formée. The technique known as "hot plaxing" is that of performing, immediately at the exit of an extrusion die, the junction of the extruded layer with a layer of material previously formed.
Ladite couche chargée comprend ainsi une très forte proportion de charges, ce qui la rend facilement imprimable soit du fait de la perméabilité des charges, soit du fait des interstices aménagés entre les charges, conférant à cette couche une structure relativement poreuse, soit du fait de la polarité de ces charges. Said loaded layer thus comprises a very high proportion of fillers, which makes it easily printable either due to the permeability of the fillers, or due to the interstices arranged between the fillers, giving this layer a relatively porous structure, or due to the polarity of these charges.
En dessous d'une proportion de 50 %, les charges sont trop enrobées pour rendre le matériau imprimable dans de bonnes conditions et, au-delà d'une proportion de 95 %, la cohésion de la couche chargée devient trop aléatoire pour permettre sa liaison avec la couche de base par l'une ou l'autre des techniques précitées, ou pour permettre l'utilisation de ce matériau dans l'application précitée. Below a proportion of 50%, the fillers are too coated to make the material printable under good conditions and, above a proportion of 95%, the cohesion of the loaded layer becomes too random to allow its bonding with the base layer by either of the aforementioned techniques, or to allow the use of this material in the aforementioned application.
La couche chargée a une résistance intrinsèque faible, mais la résistance du matériau, notamment à la pliure, est conférée par la couche de base. The loaded layer has a low intrinsic resistance, but the resistance of the material, in particular to bending, is imparted by the base layer.
L'épaisseur de ce matériau peut aller de 200 à 4000 pm. L'épaisseur de la couche chargée peut être relativement faible par rapport à l'épaisseur totale, et ne représenter par exemple que 3 à 10 % de celle-ci. The thickness of this material can range from 200 to 4000 µm. The thickness of the loaded layer can be relatively small compared to the total thickness, and represent for example only 3 to 10% thereof.
Les charges peuvent être sous forme pulvérulente, ou sous forme de fibres, de bâtonnets ou autres. The fillers may be in powder form, or in the form of fibers, sticks or the like.
Leur nature peut être très variée en fonction des caractéristiques désirées. I1 peut notamment s'agir de talc, de craie, de magnésie, de kaolin, de polyester, de verre, de chanvre, de lin, de coton. Their nature can be very varied depending on the desired characteristics. It can in particular be talc, chalk, magnesia, kaolin, polyester, glass, hemp, flax, cotton.
