It has a support paper material with a surface covering of at least expanded thermoplastic micro-spheres and a bonding agent forming the right paper surface. The paper has a static friction coefficient between the right and left surfaces of ≤ 0.95 and pref. ≤ 0.90. The paper weight is 70-500 g/m<2> and pref. 200-400 g/m<2>. The support paper is transparent or translucent, and especially a tracing paper, pref. from pressure refining of cellulose fibers. The covering layer on the right surface has a weight of 6-20 g/m<2> and pref. 8-17 g/m<2>. The covering layer is composed of 5-12 dry wt% of expanded thermoplastic micro-spheres and pref. 6-9 wt%, 15-95 dry wt% of a bonding agent with a glazing temp. of (-) 10 degrees C to (+) 35 degrees and pref. 20-40 wt%, 0-75 dry wt% of mineral pigments and pref. 40-75 wt% and 0-40 dry wt% of dyestuff, to give a total of 100 wt%. The expanded thermoplastic micro-spheres contain a gas, which expands at a temp. of 90-115 degrees C and pref. 100-110 degrees C. The surface covering has a low friction component in a distribution of 0.1-5.0 g/m<2> and pref. 0.3-3.0 g/m<2>. At least one surface contains a salt which can be ionized, and particularly sodium chloride. The support paper has a coloring at least under the layer of micro-spheres and/or a layer and/or a print which can be seen through the layer. An Independent claim is included for a paper prodn. process where the support paper is formed from a cellulose fiber suspension in water together with synthetic fibers if required. It is mixed with minerals, at least one bonding agent and a dye, an agent to resist moisture and other conventional papermaking additives. The left surface of the paper is coated with a material to reduce friction, and the paper is dried at 100 degrees C. The right surface of the paper is coated with a mixture of thermoplastic micro-spheres together with a bonding agent and mineral pigments and dyestuff. The coated paper is heated at 90-115 degrees C to dry the paper and expand the micro-spheres and pref. 100-110 degrees C. The paper is wound into a roll. Preferred Features: The low friction coating is applied by a glue press using a double-sided transfer film and the drying is through an air cushion. The cellulose fibers are refined to a high state and pref. ≥ 90 degrees SR. A further Independent claim is included for a wrapping process where the paper is drawn off the roll and cut into sheets in the required format. The sheets are printed at a speed of ≥ 8000 sheets/hr., and the printed sheets are cut to size. An adhesive is applied to either surface where the wrapping is to be secured. The products are wrapped, with the layer containing the expanded thermoplastic micro-spheres on the outer side.

Description

La présente invention concerne une feuille ayant un toucher rappelant la peau et imprimable à des cadences élevées. Elle concerne en particulier une feuille d'emballage comportant une caractéristique en liaison avec le produit à emballer, et plus particulièrement destinée à l'emballage de luxe pour les produits cosmétiques. Elle concerne aussi le procédé de fabrication de la feuille et de l'emballage ainsi que l'emballage lui-même.The present invention relates to a sheet having a feel reminiscent of the skin and printable at high speeds. It relates in particular to a packaging sheet having a characteristic in connection with the product to be packaged, and more particularly intended for luxury packaging for cosmetic products. She also relates to the manufacturing process of the sheet and the packaging as well as the packaging himself.

Les emballages, en particulier de luxe pour les produits cosmétiques, sont réalisés à partir de feuilles en papier ou carton pouvant être colorées, embossées ou grainées, et portant des impressions avec des motifs, la marque du produit et le nom du laboratoire ou parfumeur le fabriquant. Ces emballages se distinguent principalement par l'effet visuel qui résultent des impressions et le cas échéant du grain de la feuille.Packaging, particularly luxury packaging for cosmetic products, is made at from sheets of paper or cardboard which can be colored, embossed or grained, and bearing prints with patterns, the brand of the product and the name of the laboratory or perfumer making it. These packaging are mainly distinguished by the visual effect which result from impressions and, where appropriate, from the grain of the sheet.

La Demanderesse s'est intéressée en particulier à fournir une feuille d'emballage qui comporterait une caractéristique qui rappellerait l'une des caractéristiques essentielles du produit à emballer, en particulier pour les produits cosmétiques à appliquer sur la peau.The Applicant is particularly interested in providing a packaging sheet which would have a characteristic which would recall one of the essential characteristics of the product to be packaged, in particular for cosmetic products to be applied to the skin.

La Demanderesse propose alors de fournir une caractéristique qui évoque la destination, à savoir la peau, c'est à dire le toucher, la douceur de la peau.The Applicant then proposes to provide a characteristic which evokes the destination, namely the skin, ie the touch, the softness of the skin.

Pour donner un toucher plus doux à une feuille il est connu d'y appliquer par un traitement de surface, en particulier par imprégnation, une composition d'un polymère en dispersion aqueuse (latex). Cependant le toucher est encore trop éloigné d'un toucher "peau".To give a softer feel to a leaf it is known to apply it by a surface treatment, in particular by impregnation, a composition of a polymer aqueous dispersion (latex). However touch is still too far from a touch "skin".

La Demanderesse a trouvé qu'un toucher "peau" pouvait être obtenu en appliquant à la surface de la feuille une couche qui comporte des microsphères thermoplastiques expansibles.The Applicant has found that a "skin" feel could be obtained by applying to the surface of the sheet a layer which includes thermoplastic microspheres expandable.

Il est connu d'utiliser ce type de microsphères expansibles soit en masse pour augmenter le volume massique d'un papier soit en surface d'une feuille de papier pour y conférer des propriétés antiglisse comme décrit dans les demandes de brevet EP 549 948 , FR 2395141, FR 2635506, JP 63146945 ou le brevet US 4753831.It is known to use this type of expandable microspheres either by mass for increase the mass volume of a paper either on the surface of a sheet of paper to confer anti-slip properties as described in patent applications EP 549 948, FR 2395141, FR 2635506, JP 63146945 or US patent 4753831.

Néanmoins, dans le cas de l'application de ces microsphères en surface, se posent des problèmes de machinabilité de ces feuilles car elles ne sont ni enroulables ni manipulables comme des feuilles classiques. En effet leurs propriétés antiglisse vont engendrer une certaine friction lorsque la "face peau" est soumise à un frottement et par conséquent va gêner le bon enroulement et déroulement des feuilles en bobine et, dans le cas de feuilles découpées en formats, va empêcher la bonne séparation des feuilles les unes des autres dans la pile à traiter. Pour éviter le plus possible cet handicap, il faut que l'étape d'expansion des microsphères soit réalisée le plus tard possible dans la chaine de transformation, après l'impression ou lors du façonnage des articles.However, in the case of the application of these microspheres on the surface, arise problems with the machinability of these sheets because they are neither rollable nor can be handled like conventional sheets. Indeed their anti-slip properties go generate some friction when the "skin side" is subjected to friction and by consequently will hinder the good winding and unwinding of the sheets in reel and, in the case of sheets cut into formats, will prevent the good separation of the sheets of others in the stack to be processed. To avoid this handicap as much as possible, it is necessary that the stage expansion of the microspheres is carried out as late as possible in the chain of transformation, after printing or during the shaping of articles.

Il n'est donc pas évident de proposer la solution énoncée ci-dessus dans la mesure où l'effet "peau" va s'opposer à la bonne machinabilité des feuilles sur les machines d'impression ou de transformation.It is therefore not easy to propose the solution set out above since the "skin" effect will oppose the good machinability of the leaves on the machines printing or processing.

Or il est important de pouvoir imprimer et transformer ces feuilles aux cadences habituelles de façon à ne pas rajouter de surcoût; par exemple les cadences sont de l'ordre de 8000 voire jusqu'à 15000 feuilles à l'heure sur les machines d'impression en offset.However it is important to be able to print and transform these sheets at the rate usual so as not to add any additional cost; for example the cadences are around 8,000 or even up to 15,000 sheets per hour on offset printing machines.

De surcroít, il faut que les feuilles sur l'autre face verso soit réceptrice à des colles afin qu'elles soient aptes à être transformées en boítes par exemple.In addition, it is necessary that the leaves on the other back side is receptive to glues so that they are able to be transformed into boxes for example.

L'invention fournit une feuille présentant sur l'une de ces faces un toucher rappelant la peau, dite face recto, et étant imprimable à des cadences élevées, ladite feuille comprenant une feuille support revêtue sur l'une de ces faces d'une couche comportant au moins des microsphères thermoplastiques expansées et un liant, formant ladite face recto, et ladite feuille ayant un coefficient de friction statique entre ladite face recto et l'autre face verso inférieur à 0,95, de préférence inférieur ou égal à 0,90, mesure faite selon la norme NF-Q-03-082 avec un patin de 200g.The invention provides a sheet having on one of these faces a touch reminding the skin, known as the front side, and being printable at high rates, said sheet comprising a support sheet coated on one of these faces with a layer comprising at least less expanded thermoplastic microspheres and a binder, forming said front face, and said sheet having a coefficient of static friction between said front face and the other face back less than 0.95, preferably less than or equal to 0.90, measurement made in accordance with the standard NF-Q-03-082 with a 200g skate.

Le coefficient de friction statique reflète l'aptitude de la feuille à se bloquer au départ d'un déplacement; plus il est élevé, plus l'amorce du mouvement d'une feuille dans une pile sera difficile.The coefficient of static friction reflects the ability of the sheet to block when departure of a trip; the higher it is, the more the beginning of the movement of a leaf in a pile will be difficult.

En particulier l'invention se caractérise par le fait que ladite feuille a un grammage compris entre 70 et 500 g/m2, de préférence entre 200 et 400 g/m2.In particular, the invention is characterized in that the said sheet has a basis weight between 70 and 500 g / m 2 , preferably between 200 and 400 g / m 2 .

Selon un cas particulier, l'invention se caractérise par le fait que ladite feuille support est transparente ou tranlucide. Plus particulièrement ladite feuille support est une feuille de papier calque. On entend par papier calque, un papier tel que défini par la norme internationale ISO 4046-1978 au point 6.94. Plus particulièrement l'invention se caractérise par le fait que ladite feuille support est une feuille de papier calque, en particulier obtenue par un raffinage poussé des fibres de cellulose la composant.

More particularly the invention is characterized by the fact that said support sheet is a sheet of tracing paper, in particular obtained by a thorough refining of the cellulose fibers composing it.
