Abstract
Description
L'invention concerne les papiers pour cigarettes roulées à la main, également appelés papiers carnets ou papiers à rouler.The invention relates to hand-rolled cigarette papers, also called note papers or rolling papers.
Ce type de papier doit classiquement répondre à des contraintes particulières, et notamment à des contraintes esthétiques consistant principalement en une faible opacité.This type of paper must conventionally meet constraints particular, and in particular to aesthetic constraints consisting mainly in low opacity.
Pour réduire les goudrons, diverses techniques sont connues, notamment le fait d'augmenter la porosité du papier. Mais dans le cadre des papiers à rouler, qui sont des papiers légers ainsi que présentant de faibles taux de charge, l'augmentation de la porosité est une technique peu efficace. En effet, non seulement l'augmentation de porosité s'avère avoir peu d'influence sur le taux de goudrons, mais de plus l'augmentation de porosité se heurte à des limites beaucoup plus strictes en matière de faisabilité.To reduce tars, various techniques are known, including increasing the porosity of the paper. But in the context of rolling papers, which are light papers as well as having low charge rate, increasing porosity is a technique that effective. Indeed, not only does the increase in porosity turn out to have little influence on the tar rate, but moreover the increase in porosity comes up against much stricter limits when it comes to feasibility.
Ainsi, pour réduire les goudrons dans le cadre des cigarettes à rouler, le principal effort mis en oeuvre jusqu'à présent a été d'augmenter la perméabilité à l'air par électroperforation.So, to reduce the tar in the context of rolling cigarettes, the main effort to date has been to increase the air permeability by electroperforation.
En effet, en faisant varier le taux de charge, l'homme du métier est confronté à deux contraintes antagonistes :Indeed, by varying the charge rate, the skilled person is faced with two conflicting constraints:
Plus le taux de charge dans le papier est faible, et plus les goudrons dégagés par la cigarette sont importants. De plus, plus le taux de charge est élevé, plus le papier est opaque.The lower the loading rate in the paper, the more the tars given off by cigarettes are important. In addition, the lower the charge rate the higher, the more opaque the paper.
Une autre spécificité des papiers carnets est leur faible grammage. La réduction des goudrons des cigarettes RYO passe aussi par une augmentation du grammage de ces papiers, donc de leur opacité.Another specificity of notebooks is their low grammage. Tar reduction in RYO cigarettes also involves increased grammage of these papers, therefore of their opacity.
Avec ces deux contraintes, aucun poids ni taux de charge n'a apporté jusqu'à présent de solution satisfaisante en termes à la fois de réduction des goudrons et de maintien d'une opacité faible.With these two constraints, no weight or load rate has brought so far a satisfactory solution in terms of both reducing tar and maintaining low opacity.
L'invention se propose de répondre à cette double contrainte, c'est-à-dire de proposer un papier dont les cigarettes émettent peu de goudrons, mais qui reste un papier à faible opacité.The invention proposes to respond to this double constraint, that is to say to offer a paper whose cigarettes emit little tar, but which remains a paper with low opacity.
Un tel papier est, selon l'invention, un papier à cigarettes de type à rouler, chargé en carbonate de calcium, caractérisé en ce que le carbonate de calcium présente une taille moyenne de particules supérieure à trois microns.According to the invention, such a paper is a cigarette paper of the type with roll, loaded with calcium carbonate, characterized in that the carbonate of calcium has an average particle size greater than three microns.
On propose en outre selon l'invention une utilisation particulière d'un carbonate de calcium ayant une taille moyenne de particules supérieure à trois microns, en tant que charge dans un papier à cigarette à rouler pour réduire l'émission de goudrons au fumage tout en conservant une opacité inférieure à 70%, selon la norme ISO 2471.According to the invention, a particular use of a calcium carbonate having an average particle size greater than three microns, as a filler in a rolling cigarette paper for reduce the emission of tar during smoking while maintaining opacity less than 70%, according to ISO 2471.
On propose également selon l'invention un carnet de papiers à cigarettes, caractérisé en ce qu'il inclut une pile de papiers à cigarette tels que précédemment annoncés.According to the invention, a paper notebook is also proposed. cigarettes, characterized in that it includes a stack of cigarette papers such than previously announced.
On décrira maintenant un exemple privilégié de mise en oeuvre de l'invention.We will now describe a privileged example of implementation of the invention.
On utilise un papier de départ qui est ici un papier carnet de type hollandais connu sous la référence 405 SA 65.We use a starting paper which is here a notebook type paper Dutch known by the reference 405 SA 65.
On voit qu'en augmentant la porosité pour obtenir le 411, les goudrons ont peu baissé : c'est parce que comme le poids et le taux de charge n'ont pas été modifiés, la combustibilité des articles à fumer a peu changé, et de ce fait les goudrons peu baissé. C'est la même chose avec le 245 SA 100 où la perméabilité a été augmentée, sans effet notoire sur les rendements en goudrons. Par contre avec le 450 SA 150 où poids et taux de charge ont été significativement augmentés, tout en gardant une opacité faible, les goudrons ont significativement baissé. Ce résultat est obtenu grâce à l'augmentation de combustibilité apportée par l'augmentation de grammage et de taux de charge, et par l'augmentation de la perméabilité finale.We see that by increasing the porosity to obtain 411, the tars have fallen little: this is because as the weight and the rate of loads have not been modified, the combustibility of the smoking articles has little changed, and as a result the tars dropped slightly. It's the same with the 245 SA 100 where the permeability has been increased, without noticeable effect on the tar yields. On the other hand with the 450 SA 150 where weight and rate load have been significantly increased, while maintaining opacity low, the tars fell significantly. This result is obtained thanks to the increase in combustibility brought about by the increase in grammage and load rate, and by increasing the permeability final.
Le carbonate de calcium chargeant le papier est pour cela un carbonate de calcium précipité disponible sous la référence ADX 7014 an. N°21390.The calcium carbonate loading the paper is therefore a precipitated calcium carbonate available under the reference ADX 7014 year. No. 21390.
Ce carbonate de calcium peut être obtenu auprès de la société Specialty Minerals, Inc., de Adams, Massachussetts, USA.This calcium carbonate can be obtained from the company Specialty Minerals, Inc., of Adams, Massachussetts, USA.
Ce carbonate de calcium précipité présente des propriétés intrinsèques particulières que l'on peut qualifier de la façon suivante.This precipitated calcium carbonate has properties particular intrinsics which can be described as follows.
Il possède une taille moyenne de particules élevée par rapport à l'art antérieur. It has a high average particle size compared to art prior.
Cette taille moyenne de particules est ici de 3,5 microns (contre typiquement 2 microns pour l'art antérieur), et s'avère particulièrement avantageuse en termes de maintien d'une opacité faible. De plus, cette taille moyenne de particules élevée s'avère également permettre une augmentation de porosité acceptable, permettant ainsi une réduction satisfaisante de goudrons. On détaillera ces effets dans la suite de l'exposé.This average particle size here is 3.5 microns (against typically 2 microns for the prior art), and is particularly advantageous in terms of maintaining a low opacity. In addition, this size high particle average also appears to allow acceptable increase in porosity, allowing reduction satisfactory tars. These effects will be detailed later in the presentation.
Il serait possible de maintenir une opacité faible en modifiant la forme des cristaux de carbonate habituels, mais au prix d'efforts importants.It would be possible to maintain a low opacity by modifying the shape usual carbonate crystals, but at the cost of significant efforts.
Plus généralement, on a découvert qu'on obtient des opacités faibles, en optant généralement pour des tailles de particules élevées, c'est-à-dire de préférence supérieures à 3 microns, et plus particulièrement une taille moyenne de particules qui est d'environ 3,5 microns.More generally, we discovered that we obtain weak opacities, generally opting for large particle sizes, i.e. preferably greater than 3 microns, and more particularly a size particle average which is about 3.5 microns.
On sélectionne donc avantageusement une taille moyenne de particules supérieure à 3 microns, et préférentiellement égale à 3,5 microns.We therefore advantageously select an average size of particles larger than 3 microns, and preferably equal to 3.5 microns.
Afin de pouvoir comparer les effets de ce carbonate de calcium particulier avec les effets d'un carbonate de calcium classique, on a préparé parallèlement des échantillons de papier reprenant l'ensemble des mêmes paramètres, notamment le taux de charge particulièrement élevé, hormis qu'ils sont chargés en carbonate de calcium classique.In order to compare the effects of this calcium carbonate particular with the effects of a classic calcium carbonate, we prepared parallel paper samples containing all of the same parameters, in particular the particularly high charge rate, apart from that they are loaded with classic calcium carbonate.
Bien que les résultats en termes de réduction de goudrons puissent apparaítre assez proches, les résultats en matière d'opacité sont par contre nettement différents selon que le carbonate est l'ADX 7014, c'est-à-dire le carbonate à taille de particules élevée, ou le carbonate classique.Although the results in terms of tar reduction may appear fairly close, the results in terms of opacity are however markedly different depending on whether the carbonate is ADX 7014, i.e. high particle size carbonate, or conventional carbonate.
Dans le cas du carbonate de calcium classique, une opacité de 76% est obtenue, c'est-à-dire une opacité particulièrement élevée, du type de celles relevées sur les papiers « machine » (papiers pour cigarettes roulées industriellement, typiquement à 75%).In the case of conventional calcium carbonate, an opacity of 76% is obtained, that is to say a particularly high opacity, of the type of those recorded on "machine" papers (papers for rolled cigarettes industrially, typically 75%).
Dans le cas du carbonate de type ADX 7014, l'opacité mesurée a été de 69%.In the case of carbonate type ADX 7014, the opacity measured was 69%.
Une opacité de 69%, bien qu'elle soit légèrement supérieure aux opacités habituelles des papiers à rouler (typiquement 65%), reste toutefois très limitée et bien adaptée à la réalisation d'un papier à rouler ayant de bonnes qualités visuelles. Opacity of 69%, although slightly higher than usual opacity of rolling papers (typically 65%), however remains very limited and well suited to the production of a rolling paper having good visual qualities.
Ainsi, au final, pour un papier standard chargé en carbonate de calcium selon les méthodes habituelles, mais en optant pour un carbonate de type ADX avec une augmentation de la charge dans des proportions très inhabituelles pour les papiers à rouler, il s'avère qu'on ne génère aucune opacité gênante.So, in the end, for a standard paper loaded with carbonate of calcium according to the usual methods, but opting for a carbonate ADX type with an increase in the load in very high proportions unusual for rolling papers, it turns out that we do not generate any annoying opacity.
Afin de faire mieux apparaítre la réduction de goudron obtenue grâce
à cette augmentation de la charge, on a mis en parallèle, dans le tableau ci-dessous,
le papier ainsi chargé en ADX 7014, avec une série d'autres
papiers à rouler habituels, c'est-à-dire chargés en carbonates habituels, et
avec des taux de charges habituels pour les papiers à rouler.
Ce tableau présente trois tels papiers à rouler habituels, chacun réalisé à partir d'un papier de base standard, de type hollandais (405 SA 65, 411 SA 80, 245 SA 100). Les grammages sont, pour ces papiers, situés dans des ordres de grandeur classiques de papier à rouler hollandais, c'est-à-dire compris entre 12 et 21 g/m2, typiquement à 17 g/m2 (correspondant à un taux de charge inférieur à 20 %).This table presents three such usual rolling papers, each made from a standard basic paper, of the Dutch type (405 SA 65, 411 SA 80, 245 SA 100). The grammages are, for these papers, located in conventional orders of magnitude of Dutch rolling paper, that is to say between 12 and 21 g / m 2 , typically at 17 g / m 2 (corresponding to a rate less than 20%).
Le papier selon l'invention présente lui un taux de charge de 28%, c'est-à-dire pratiquement une fois et demi le taux de charge de ces papiers classiques.The paper according to the invention has a charge rate of 28%, that is to say practically one and a half times the loading rate of these papers classics.
Le résultat en terme de goudrons dégagés est particulièrement probant. De 18 mg/cigarette pour le 405 SA 65, on est descendu à un rendement en goudrons de 13,5 mg/cigarette, c'est-à-dire de plus de 3 mg/cigarette inférieur aux rendements du papier à rouler initial. The result in terms of tars released is particularly convincing. From 18 mg / cigarette for 405 SA 65, we went down to a tar yield of 13.5 mg / cigarette, i.e. more than 3 mg / cigarette lower than the yields of the original rolling paper.
Pour obtenir ce résultat, le taux de charge de 28%, et plus généralement supérieur à 25%, est préféré.To achieve this result, the charge rate of 28%, and more generally more than 25%, is preferred.
Toutefois un taux de charge supérieur à 15% ou un grammage à partir de 17g/m2 pour le papier chargé commence déjà à donner des résultats en matière de limitation des goudrons, avec la faible opacité voulue.However, a loading rate greater than 15% or a grammage from 17 g / m 2 for the loaded paper is already starting to give results in terms of tar limitation, with the desired low opacity.
Comme annoncé déjà ci avant, l'opacité obtenue est de 69% pour le papier selon l'invention. Cette opacité est similaire à l'opacité obtenue pour les trois papiers classiques, qui est de 66% pour deux d'entre eux et de 63% pour le troisième (405SA65).As already announced above, the opacity obtained is 69% for the paper according to the invention. This opacity is similar to the opacity obtained for the three classic papers, which is 66% for two of them and 63% for the third (405SA65).
On notera que le taux de charge adopté avec le papier selon l'invention, à savoir 28%, est non seulement très supérieur aux taux de charge utilisés habituellement pour les papiers à rouler, mais se situe également dans la fourchette haute des taux de charge habituellement utilisés dans les papiers à cigarettes machine (typiquement 25 à 30 %), qui pourtant eux présentent une opacité importante, à la fois en raison du grammage du papier de départ et des charges ajoutées.It will be noted that the loading rate adopted with the paper according to the invention, namely 28%, is not only much higher than the rates of load usually used for rolling papers, but is also in the upper range of charge rates usually used in machine cigarette papers (typically 25 to 30%), which yet they exhibit significant opacity, both due to the grammage of the starting paper and added loads.
Pour information, un papier à cigarette « machine » présente typiquement un grammage (à papier chargé) qui est supérieur à 22 g/m2, classiquement de 25 g/m2.For information, a "machine" cigarette paper typically has a grammage (with loaded paper) which is greater than 22 g / m 2 , conventionally 25 g / m 2 .
Le papier préféré ici a un grammage qui correspond à un fort taux de charge tel qu'exposé ci-dessus, mais qui reste à une opacité et à un grammage suffisamment faible pour conserver un aspect de papier à rouler.The preferred paper here has a grammage which corresponds to a high rate of charge as described above, but which remains at an opacity and at a grammage low enough to maintain the appearance of rolling paper.
Ainsi donc, on a proposé ici un papier à cigarette de type à rouler comprenant un taux de charge particulièrement élevé puisque largement en dehors des limites habituelles adoptées dans les papiers à rouler (typiquement 10 à 20 %) et présentant toutefois une opacité acceptable pour un papier à rouler (opacité inférieure à 70% typiquement de l'ordre de 65%).So, we proposed here a rolling type cigarette paper including a particularly high charge rate since largely outside the usual limits adopted in rolling papers (typically 10 to 20%) and nevertheless having an acceptable opacity for a rolling paper (opacity less than 70% typically of the order of 65%).
Avantageusement, le papier à cigarette présente un grammage supérieur à 21 g/m2.Advantageously, the cigarette paper has a grammage greater than 21 g / m 2 .
On introduit ainsi par exemple le carbonate de calcium selon un taux de charge tel que le papier présente un grammage supérieur à 21 g/m2.Thus, for example, calcium carbonate is introduced at a filler rate such that the paper has a grammage greater than 21 g / m 2 .
Avantageusement aussi, on choisit un papier de base et un taux de charge tels que le grammage du papier reste inférieur à 24 g/m2.Advantageously also, a basic paper is chosen and a loading rate such that the grammage of the paper remains less than 24 g / m 2 .
