Definitions
- the invention relates to a coating method for wrapping material made of paper or cardboard for smoking products or parts of tobacco products, the coating method has the purpose of this coating material tends to absorb aqueous or oily substances, as well as the diffusion or migration of such substances through the paper or to reduce the carton. Furthermore, the invention relates to the corresponding coated cladding material.
- tipping paper for cigarettes as an exemplary casing material according to the invention.
- the reason for this is that the tipping paper is probably the most important application for the invention and that the description becomes easier to understand by focusing on only a single application. Only in the last part of the description will be briefly discussed further applications.
- Essential parts of a conventional filter cigarette are the tobacco rod, the filter and sheathing material in the form of the cigarette paper enveloping the tobacco rod, the filter wrap paper directly enveloping the filter and the tipping paper.
- the tipping paper is that part of the filter cigarette which is touched by the lips of the person smoking the cigarette when the filter cigarette is smoked, enveloping the filter part and usually extending longitudinally of the filter cigarette It is adhesively bonded to the filter wrap paper and the cigarette paper, and by making this bond, the filter part and the tobacco rod part are mechanically connected in the cigarette machine but may also be a film or a composite material of several layers of different materials.
- the tipping paper has an imprint.
- this print can be reminiscent of cork.
- EP 2551407 Bl proposes a filter wrapper which, compared to other filter wrappers, significantly better brakes oil diffusion, while still itself being a light and very porous, ie well air-permeable, paper, as is important for filter wrap papers.
- the filter wrapper paper is particularly advantageous when using filters containing liquid flavorant which is intended to enrich the smoke stream but not to diffuse so much through the filter wrapper paper and into the mouthpiece overlay paper running around the finished cigarette outside thereof visible marks appear on the visible surface of the tipping paper.
- a mouthpiece covering paper is proposed, which is coated with a composite of nitrocellulose lacquer and a cold sensation substance.
- EP 10446115 B1 proposes a cigarette paper (ie a paper intended for wrapping the tobacco rod), which is provided with a water-repellent impregnation of cellulose derivative. In order to achieve a desired good air permeability of the cigarette paper despite the impregnation, it is proposed to apply the impregnation in several successive coating operations.
- the object underlying the invention is to provide sheathing material in particular mouthpiece covering paper in that processing state, from which only one or more customized optically and / or otherwise sensory perceptible imprints are missing until processing in the cigarette machine.
- the special requirements for the tipping paper to be provided in said processing state are: The tipping paper should actually be a paper, not a foil. (This is required mainly for haptic reasons, for reasons of further printability and for reasons of processability in the cigarette machine.)
- the tipping paper coated according to the invention is said to have a significantly lower tendency to form stains due to ingestion of aqueous, oily, greasy, waxy or alcoholic substances, and diffusion of these substances through the tipping material, irrespective of other customer-specific imprints compared to other papers used as tipping paper.
- the desired "stain prevention" of the tipping pad should be reliable and independent of the properties of the base paper used.
- Liquid volatile matrix is understood to mean all types of solvents (inorganic and organic) and dispersion media of dispersions, emulsions or suspensions.
- the purpose of the first coating process is essentially to protect the paper from damage caused by the water which is forcibly applied during the second coating process. Only with the second coating process is that coating applied, which has the decisive desired effect of "stain avoidance", in particular the lowest possible tendency to build up take and migration or diffusion of aqueous, oily, waxy and alcohol-based substances causes.
- a coating process is defined as the application of a coating material, and a coating process can also consist of a time-separated application of several overlapping layers of the coating material.
- oil-repellent or oil-tight coating materials which can be applied in liquid form, are dissolved in water or aqueous solutions, or are present as a dispersion with water as a dispersion medium.
- water as a volatile liquid matrix for paper coatings can only be used to a very limited extent because untreated paper absorbs water quickly and can change to permanent uselessness, namely becoming soft and rough, enlarging its enveloping surface, causing waves and no longer being processed can.
- the second coating can be used a much larger amount than you could otherwise and thus achieve a much better desired effect ("stain prevention"), than you could otherwise. Spots are local changes in appearance by water, alcohols, solvents, waxes, fats or oils (for example, fatty oils, mineral oils, silicone oils, essential oils).
- the invention is also applicable to such a second coating whose volatile liquid matrix, while not based on water, would also undesirably alter the properties of the paper or paperboard.
- the first coating is therefore generally formulated to the absorption capacity of the
- the coating according to the invention is particularly advantageous in the case of paper grades with a low grammage (below 80 g / m 2 , preferably below 40 g / m 2 ), since the negative influence on the paper properties increases with increasing absolute moisture in the paper.
- Fig. 1 shows the schematic representation of an exemplary coating method according to the invention.
- Figure 2 Shows as a result of an ink floating test a tipping base paper coated according to the invention and two comparative papers.
- FIG. 1 shows an exemplary online process for producing a paper coated according to the invention.
- “Online” in this context means that the paper is present as a paper web 4, which is pulled through the coating system and coated continuously.
- the paper web is usually unwound from a paper roll (mother roll or reel) and wound up again after the coating to a paper roll, or further processed directly, for example, cut into strips.
- the coating according to the invention is carried out in four steps:
- the first, lower coating is applied by a coating device 1.1.
- the first coating is dried.
- the second coating is applied over the first coating in the coating device 1.2.
- the second coating is dried.
- Step can be done multiple times.
- the first and / or second coating process can be carried out by applying a plurality of layers applied one behind the other.
- the drying can be accelerated by the action of hot air or infrared radiation.
- a particularly valuable drying method for the coating according to the invention a combination of hot air and infrared drying has been found.
- the coating is, for example, first irradiated with infrared radiation, preferably from the uncoated back side of the paper. So the coating begins first in depth, so to dry on paper. This allows the evaporated solvent (or, more generally, the volatile liquid matrix) to escape through the upper, still liquid layers of the coating that are in the air. Once sufficient solvent has evaporated from the deeper layers, the evaporation of the near-surface can be Solvent by additionally accelerating the drying with
- the number and arrangement of hot air and infrared sources (2.1, 2.2, 3.1, 3.2, 3.3), as well as the intensity and duration of exposure to them, depends on the paper used and the type and quantity of paint used, and may best be determined by experiment be determined.
- one or more infrared sources (3.1, 3.2, 3.3) may be mentioned from above (coating side), one-sided from below or on both sides; one or more hot air sources (2.1, 2.2) on one side from above, one-sided from below or on both sides; and combinations of said arrangements of infrared sources (3.1, 3.2, 3.3) and hot air sources (2.1, 2.2).
- the action of the infrared sources (3.1, 3.2, 3.3) and hot air sources (2.1, 2.2) can be carried out simultaneously or staggered.
- Starting material is an exemplary pulp fiber based base paper, as is common for tipping paper. It has a grammage (basis weight) of about 20-80 g / m 2 , in the present example 35 g / m 2 .
- the readily absorbent base paper would absorb approximately the entire amount of the liquid component of the lacquer.
- the mass of the applied liquid is 11.7 g / m 2 .
- 11.7 g of water are added per 35 g of paste. applied, which corresponds to an increase in the absolute paper moisture, defined as [(wet mass - dry mass) / wet mass], of about 25 wt .-%.
- the absolute paper moisture would only increase by 12.7% by weight.
- the Applicant has found that with an increase in the regular paper moisture (4 - 7 wt .-%) to an absolute paper moisture of about 14 wt .-%, the paper properties are so adversely affected that the tipping material can not be processed properly. This illustrates the high importance of the coating according to the invention especially for absorbent paper grades with low grammage, since the absorption capacity of the paper for the liquid content of the second coating is reduced by the first coating.
- Shellac is used as a coating material for the first coating process.
- Shellac is mixed with ethanol as a solvent until a flow time of between 18 and 22 seconds results when measuring the viscosity of the mixture with the flow cup test with a cup diameter of 4 mm (ISO cup 4 mm according to EN ISO 2431 version 1993-02-15).
- Per m 2 of paper 1 to 6 grams, preferably 3 to 3.5 grams of dry application amount of this mixture are applied evenly on the base paper by gravure printing. The dry application rate can be measured as the weight increase of the paper after drying of the coating and thus represents the mass of the applied, non-volatile coating material.
- the paper is dried in air at a temperature of 70 ° C to 120 ° C for at least 1-4 seconds.
- the second coating is applied to the same side of the paper as the first coating, covering the first coating.
- styrene-acrylate paint is used, in which water is the liquid volatile matrix.
- the proportion of water is so high that, when measuring the viscosity with the outlet cup test with a cup diameter of 4 mm (ISO cup 4 mm according to EN ISO 2431 version 1993-02-15), a flow time of between 11 and 23 seconds results.
- 1 to 6 grams of dry coating of the coating material, which is present in the liquid-volatile matrix of the liquid paint is evenly applied by gravure printing.
- the paper is dried in air at a temperature of 70 ° C to 120 ° C for at least 1-4 seconds.
- Cobb300 can be used, in which case the test must be possible with both water and oil as the test fluid.
- the test with oil is based on the standard SCAN-P 37:77, which describes the Cobb-Unger method.
- the CobbU value indicates the mass (in grams) of oil that is absorbed in a standardized period of time (6, 10 or 30 seconds) on one square meter of paper.
- the modification of the test consists in determining the CobbU300 (test duration 300 sec). Cobb300 was chosen because the test duration is approximately the same as the duration of smoking a cigarette.
- a Cobb300 value or CobbU300 value of less than 1 g / m 2 results in a successful coating at two test liquids less than 0.5 g / m 2 returnsszunah- According to the paper during the test period through the coated surface recorded test liquid.
- the standard CobbU30 value (test duration 30 seconds with oil) is therefore also less than 1 g / m 2 or less than 0.5 g / m 2 .
- the official name of the KIT test is "Grease resistance test for paper and paperboard T 559 cm-12".
- the relevant standardization body is TAPPI (Technical Association of the Pulp and Paper Industry) 12 well-defined oily liquids are added dropwise and it is observed for each drop, whether the respective liquid penetrates to the second surface within a standardized test period. The oily liquids are numbered and have more diffusibility with increasing number. The result of the test is the highest of those Numbers to which the associated liquid does not penetrate the second paper surface during the test period.)
- the first coating process are in addition to said shellac as coating materials and ethylcellulose paint (preferably applied in several layers), alkyd resin or nitrocellulose lacquer, wherein combinations of said coatings are particularly advantageous applicable, such as a mixture of shellac and nitrocellulose lacquer or ethyl - cellulosic lacquer or a mixture of alkyd resin lacquer and nitrocellulose luloselack or ethylcellulose lacquer.
- ethylcellulose paint preferably applied in several layers
- alkyd resin or nitrocellulose lacquer wherein combinations of said coatings are particularly advantageous applicable, such as a mixture of shellac and nitrocellulose lacquer or ethyl - cellulosic lacquer or a mixture of alkyd resin lacquer and nitrocellulose luloselack or ethylcellulose lacquer.
- Lacquer combinations can also be used advantageously in combination with paraffin wax, for example nitrocellulose lacquer, alkyd resin lacquer or ethylcellulose lacquer in combination with paraffin wax.
- paraffin wax for example nitrocellulose lacquer, alkyd resin lacquer or ethylcellulose lacquer in combination with paraffin wax.
- paints and coating materials with similar physical properties to the paints mentioned above, especially in terms of tightness and hydrophobicity can be used.
- an organic solvent ethyl acetate, for example, may well be used instead of ethanol.
- the viscosity of the still liquid coating mixture for the first coating process should be such that the flow-through cup test results in a flow time of between 13 and 35 seconds (preferably 18-22 seconds). As the viscosity increases, the concentration of the coating material is higher and more of it is applied per printing process, but it also becomes more difficult to get the coating tightly sealed.
- a dry application of the coating material of 1 to 6 g / m 2 should be applied to the coating mixture, preferably at least 3 g / m 2 .
- lacquers and coating materials with similar physical properties in particular with regard to impermeability, hydrophobicity and wettability by oily substances, are generally also suitable for the second coating process.
- the viscosity of the still liquid coating mixture for the second coating operation should be such that the outflow cup test results in a flow time of between 11 and 23 seconds, preferably 11 and 12 seconds.
- the coating materials of both coatings are preferably transparent and colorless, but may also contain a colorant. Furthermore, it is possible to add additives and further components such as waxes and resins, for example paraffin wax, to the coating mixtures.
- the first coating in the case of ethylcellulose lacquer, the first coating can be multilayered even when using other lacquers, the same applies to the second coating.
- the coating according to the invention is also advantageous if-unlike the example mentioned-papers are used which are already referred to as "wet-strength", because they are better wet-strength by the type of additives contained in the paper (wet strength or wet strength sizing) are as usual papers.
- the ability to absorb and diffuse aqueous or oily substances is further reduced in this case from a lower baseline.
- one can make do with less thick layer application according to the invention more or less amount of liquid coating mixture or less or more volatile liquid matrix).
- the so-called Ink-floating method very good.
- the coated paper is placed with the coated side down on the liquid level of an ink bath (with standardized ink) and it is observed whether and in which time ink penetrates to the top of the paper and discolored.
- a time of at least 15 seconds is measured before ink penetrates to the top of the paper. After the second coating process, this measured time is more than 300 seconds.
- Fig. 2 the result of the ink floating test is shown after 300 seconds.
- a typical tipping paper was used.
- the uncoated paper can be recognized as a black area bounded by a white frame, since it is already completely saturated with the ink.
- the mottled surface of the single-coated paper shows that the ink has already penetrated the paper at the black spots.
- the tipping paper provided with two different coatings according to the invention does not show any signs of discoloration and can be recognized as a white rectangle.
- the coating according to the invention Since the cigarette usually comes into contact with the lips of the smoker during smoking at its ends facing away from the tobacco rod, it is exposed to moisture in this area, which acts differently depending on the smoking habit on the cigarette. This may cause the paper to soften the cigarette and adhere to the smoker's lips.
- the coating according to the invention is also outstandingly suitable for the solution of this problem.
- the coating according to the invention is applied to the outside of the area of the smoking article which comes into contact with the lips of the smoker. In modern filter cigarettes, this is approximately the third of the mouthpiece covering paper facing away from the tobacco part.
- the tipping paper can also be coated before the composition of the cigarette.
- the second paper side is still good water absorption. This is highly desirable in the processing of tipping paper in the cigarette machine, where the speed of processing depends substantially on how quickly an adhesion of tipping paper wrapped around the filter part to the overlap location of the tipping paper has reached a certain minimum strength by itself. The increase in strength increases with the ability of the paper to absorb moisture from the glue used for said bonding. If only one paper side is coated according to the invention, at least one of the two paper surfaces to be joined together is still receptive to liquids or moisture during bonding. This achieves an acceptably rapid increase in the strength of the bond. (Tipping papers which are formed from a continuous non-absorbent film or consist of consistently high wet strength sized paper are problematic in this regard.)
- the tipping paper in both directions (out of the filter and into the filter), it makes sense to coat it on both sides according to the invention.
- the coating By applying the coating as printing, it is quite possible and advantageous to leave individual surface areas unprinted on one side of the paper, in particular precisely those surface areas which serve as bonding surfaces of the tipping paper during processing of the paper in the cigarette machine. This is especially valuable for the overlap area - and therefore bonding area - of the tipping paper on the cigarette itself. However, it is also useful for the bonding surface area of the tipping paper with the filter paper and the cigarette paper.
- the advantages of a coating according to the invention applied to the outside of the tipping paper are: a) The surface is much better suited for further printing with optical or haptic lacquers than an untreated paper surface since it is much smoother, denser and more error-free. It is therefore possible to print finer and more varied structures and generally requires less printing material. b) The surface has a so-called lip-release effect, that is, it does not tend to stick to the lips even after prolonged contact with wet lips - as is the smoking habits in some countries. It was also surprisingly found that the lip-release effect was even improved with the method according to the invention over known coating methods.
- the coated surface prevents sensory-active substances, such as typically flavorings often applied locally on the outside of the tipping paper, from spreading in the tipping paper, mixing with other materials also applied to the tipping paper, or even partially into the filter and further enter the smoke stream. It thus makes it possible to use a wider range of sensory substances, to apply a wider range of combinations of these substances to a cigarette and also to provide a greater amount of these substances on the outside of the tipping paper than would otherwise be possible.
- sensory-active substances such as typically flavorings often applied locally on the outside of the tipping paper
- the coating according to the invention When the coating according to the invention is applied to the inside of the tipping paper, its main benefit is that it prevents substances from the inside of the coated area from reaching the outside of the tipping paper diffuse there and cause visible stains and / or an undesirable odor or taste sensation. Particularly important is this type of barrier, if in the filter part or in the tobacco rod of the cigarette in addition to the present without any flavor present by the tobacco, separate flavorings are housed, which are or include oily substances. Particularly significant in number here are the originally from Indonesia so-called Kretekzigaretten in which the tobacco clove oil, as a liquid or as shredded cloves and usually various other additives such as glycerin, molasses, palm sugar, cane sugar or other flavors are added.
- a recent major trend is the use of so-called flavor capsules, mainly for attachment in the filter of cigarettes.
- a flavor capsule is a capsule whose outer shell, for example, by the exertion of pressure, is destructible. As a result, the flavorings contained in the capsule in liquid form and their carrier substances are released.
- the coating according to the invention is also ideally suited here to prevent the passage of these substances to the outside of the cigarette.
- microcapsules in the form of microscopically small aroma capsules directly on the outside of the mouthpiece covering paper.
- the coating according to the invention is suitable for preventing the passage of the substances contained therein into the interior of the cigarette.
- vanilla or menthol are used as flavorings for aroma capsules, microcapsules or direct printing.
- PEG polyethylene glycol
- the coating according to the invention is applied only to the inside of the tipping paper, it can be perceived as a haptic advantage that the tipping paper approaches the cigarette feels velvety and less film-like than it would feel if it were also coated there according to the invention.
- the invention can be remedied here by the packaging material consisting of paper or cardboard is coated according to the invention at least on the inside.
- the packaging material consisting of paper or cardboard
- the innerliner is the inner, flexible shell of a package consisting of several nested casings, with the shell surrounding the inner liner made of a stiffer material.
