Description

Printing method of patterned wrapping paper

The present invention generally relates to a method for making a cigarette wrapper having an applied pattern of additional material. In particular, the present invention relates to a method for making a cigarette wrapper having a specially formulated oxidized starch material.

The wrapper for cigarettes can be made into a pattern with additional materials to reduce the tendency of the smoking article to be made using the wrapper. The characteristic of lowering the tendency to ignite means that when the smoking article is inadvertently left on the substrate without being noticed, the ability of the smoking article to cause the burning of the substrate can be reduced.

In accordance with the present invention, a predetermined pattern of additional material containing an aqueous starch solution can be applied to the base web of the wrapper. The predetermined pattern may include a plurality of transverse strips, a plurality of longitudinal strips, a two-dimensional array of processed areas, or any other suitable pattern. These predetermined patterns are preferably applied by printing techniques such as gravure printing, lithography, ink jet printing, spray coating, stamping, and the like. The best use of gravure printing.

In order to improve the characteristics of the ignition tendency of the smoking article made of the wrapping paper, it is preferred to apply a printing solution containing oxidized starch to the pattern. Preferred printing characteristics can be achieved with an aqueous starch solution having a room temperature viscosity of no greater than about 50 mPa ‧ ns (cP) and preferably from about 4 to about 40 microns when dried. At the same time, about 90% of the particles are in the range of about 10 to about 100 microns when wet. In addition, the starch solution can preferably be slightly acidic and have a pH in the range of from about 6 to about 6.5. The starch used in the printing solution is preferably mixed with water to form a printing solution having a starch concentration of from about 20% to about 24% by weight. Another desirable property of the printing solution is a relatively high surface tension, for example, a rating of 6.5 x 10 -2 Nm -1 (65 dynes/cm) or higher.

The printing solution can be applied to the base web in two or more layers if necessary. The layers may be vertically aligned with each other, offset from each other, and some portions are spaced apart from each other. Further, if necessary, a conventional filler such as calcium carbonate may be contained in one or more layers of a thin layer.

In general, a predetermined pattern of additional material can be applied to the base web of the wrapper to achieve improved ignition tendency ("IP") characteristics, as well as improved self-extinguishing ("SE") characteristics. The tendency to ignite is a standard test conducted in accordance with ASTM E 2187-04, "Standard Test Method for Measuring the Combustion Strength of Smoking Articles," which is incorporated by reference in its entirety. Ignition propensity measures When a smoking article is placed on a substrate, the smoking article will generate enough heat to maintain the chance of static burning of the tobacco rod. It is desirable to have a low IP value because such values represent a lower likelihood of smoldering smoking articles causing the underlying substrate to burn.

In addition, the predetermined pattern of additional material is typically applied to a base web having a permeability ranging from about 20 to about 80 CORESTA units. When dry, the additional material typically forms a film on the base web that effectively reduces the permeability locally, allowing the value to range from 0 to about 10 CORESTA units. In some applications, such additional materials are applied in the form of an aqueous solution comprising starch.

I accidentally discovered that when patterned base paper is made into smoking articles Certain characteristics of the starch material can cause the preset pattern to produce a very low ignition tendency value. A more surprising understanding is that in the standard specifications of some well-known starch materials, the variation in material properties between batches affects the ignition tendency of the resulting smoking article. For example, the specifications of the Flo-Max 8 oxidized potato starch product provided by the National Starch & Chemical Company can be found that the pH of the 1% solution is in the range of 4.5 to 6.5, while the molecular weight of the particles is exceeded. 10,000. Surprisingly, when a Flo-Max 8 batch with a pH in the range of about 6 to 6.5 is applied to the base web, it is about less than 6 with other pH values but still within the manufacturer's specifications. The ignition tendency of Flo-Max 8 compared to its batch has been found to have a very significant improvement.

The starch parameters selected for the application of the film to the wrapper will require a variety of different equilibrium or exchange considerations. For example, although high molecular weight starch can effectively reduce permeability, such high molecular weight starch can only be used at low concentrations, resulting in a solution having a very high water content. However, a film having a high water content is difficult to be effectively dried on a porous wrapping paper. In addition, it has been found that the surface tension of the starch solution affects the retention of small bubbles. A low surface tension allows smaller bubbles to stay in solution, but high surface tension causes the bubbles to collect and separate from the solution, resulting in application. A more uniform and consistent material on the wrapper.

Although not fully understood, the preferred pH range for oxidized starch is believed to result in a lower degree of oxidation of the starch polymer chain - or less complete, resulting in a starch that is more acidic (ie, lower pH). More and longer polymer chains.

In addition, longer polymer chains can produce solutions with higher viscosities. When a higher viscosity starch solution is applied to the wrapper in a printing process, Better control results can be obtained.

Based on these findings, the study found that the patterned wrapper formed by the starch solution with special and improved properties has a significant improvement in the ignition tendency. The characteristics of the aqueous solution containing oxidized starch include: pH in the range of from about 6 to about 6.5; surface tension of at least about 6.5 x 10 -2 Nm -1 (65 dynes/cm); room temperature viscosity not greater than about 50 mPa ‧ s; and the particle size distribution of the dried particles is in the range of from about 4 to about 40 microns, while about 90% of the particles in the range of from 10 to about 100 microns when wet. Further, the particles preferably have a molecular weight such that the solution has a starch concentration in the range of from about 20% to about 24%. Preferably, the starch can comprise oxidized tapioca starch.

Aqueous starch solutions for use in base webs or wrappers are typically prepared by making a starch/water mixture by first applying the desired weight of dry starch powder to the desired weight of room temperature water (ie, at about 15 ° C). Mix together to about 25 ° C to obtain a starch/water mixture with a preset concentration. For example, to prepare a starch/water solution having a preset concentration of 20%, 20 parts by weight of starch must be mixed with 80 parts by weight of water. The starch/water solution is then heated in an elevated sub-boiling temperature range of from about 90 ° C to about 95 ° C (ie, a temperature below the boiling point). The starch/water solution is maintained at this elevated temperature for about 20 to about 30 minutes to render it soaked. The starch/water solution was then cooled to room temperature. The cooling step can be carried out in a passive manner, for example by a naturally occurring heat transfer method; or the cooling step can be carried out in an active (mandatory) manner, for example by immersion in a cooling bath or using a conventional mechanical cooling system. The starch/water mixture must be stirred throughout the agitation step, the heating step, the soaking step, and the cooling step. Stirring can be continuous or substantially continuous. If there is When additional ingredients, such as calcium carbonate, are incorporated into the starch/water solution, those ingredients must be added after the starch/water solution has been subjected to the soaking step and returned to room temperature.

Aqueous starch solutions having the properties listed above and prepared in the foregoing manner can be applied to the base web using any of a number of printing techniques, including (by way of example only and not limitation) by gravure, lithographic, ink jet A group of printing, painting, and stamping. Other printing methods may also be suitable for use and may be included within the scope of the teachings of this patent application. However, it is preferred to apply a starch solution to the base web using gravure printing to obtain a patterned wrapper.

For example (please refer to Figure 1), the base web 10 of the wrapper is fed from the bobbin 12 to the gravure printing system 14 where a predetermined pattern of starch solution prepared in accordance with the foregoing description is applied to the base web 10. A base web 10 having a newly applied preset pattern is collected over the collection bobbin 16. In other conventional steps, the bobbin 16 of the patterned wrapper can be used to make a tobacco rod for making a smoking article, such as a cigarette.

Gravure printing system 14 can include one, two, three or more printer operations 14a, 14b, 14c. These operations are basically the same, and the details describing one of them are sufficient to understand the corresponding details of other operations. The starch solution described above can be fed to a sump 20 which is then pumped or otherwise supplied to a gravure roll 22 having a patterned surface. This roller 22 rolls in the bath of the starch solution. When the gravure roll 22 rolls, the starch solution is wiped off the surface of the roll by the doctor blade assembly 23, so when the gravure roll 22 and the base web 10 are in the gravure roll 22 and the elastic coated reverse roll 24 The starch solution transfers the pattern on the surface of the gravure roll 22 to the base web upon contact between the nips.

After appropriate drying, the base web 10 can be sent to one or more other printing operations 14b, 14c where one or more additional starch materials can be applied to the base network in the same or different predetermined patterns. 10. The starch material in other printing operations may contain other ingredients, such as calcium carbonate, if desired. Additionally, if desired, the calcium carbonate containing starch solution can be applied to the first printing operation 14a while the calcium carbonate free starch solution is applied to the second or subsequent printing operations 14b, 14c.

The base network 10 (see Figure 2) typically has a landscape or cross-web direction (indicated by arrow 30) and a portrait orientation (indicated by arrow 32). The predetermined pattern of additional material may include a plurality of lateral (generally parallel) regions or strips 34. These strips may be evenly spaced along the length of the base web 10, or may be arranged in a repeating pattern of spacing in the direction of the length of the tobacco rod and the article of manufacture of the finished cigarette.

Alternatively, the base web 10 may include, for example, a longitudinally extending region of one or more additional materials or a predetermined pattern of stripes 36 (please refer to Figure 3). The preset pattern may also include a two-dimensional array area 38 of additional material (refer to Figure 4) that is spaced along the base web 10 and/or across the base web, if desired.

Further, as described above, the additional material may be applied to the thin layers 40, 42 of two or more layers (refer to Fig. 5). These thin layers can be perfectly aligned with each other and have a common space, if desired. Alternatively, the upper layer 42 can be divided or cut into two portions 42a, 42b, each superposed on top of the first or lower layer 40, with a space between the two portions 42a, 42b. This space may be in the longitudinal direction of the base network 10 or the horizontal axis Extend in the direction. Alternatively, the upper layer 42 may be stacked on the lower layer 40 without a common space therebetween.

The smoking article (please refer to Fig. 6) includes a tobacco rod 205 and a filter 207 which are connected to each other by a filter paper 209. The tobacco rod 205 includes a wrapper 210 constructed in accordance with the teachings of the present invention.

When the word "about" is used in conjunction with a numerical value in this patent application, it is meant that the accompanying numerical value will include the stated value plus a tolerance of ±10%. Further, when a percentage is mentioned in the application of the present invention, it means a percentage based on the weight, that is, a weight percentage.

Obviously, a new, improved and non-obvious method for making a method of making a patterned wrapper has been described in detail in the present application, which has the general technical ability in this technical field. Can understand. In addition, it will be apparent to those skilled in the art that various modifications, variations, substitutions, and equivalents may be made without departing from the spirit and scope of the invention.
