圖案化包裝紙之印刷方法Printing method of patterned wrapping paper

本發明大致上係關於一種用於製造具有附加材料之施加圖案的香煙包裝紙之方法。特別是，本發明係關於一種用於製造具有特殊配方氧化澱粉材料的香煙包裝紙之方法。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.

香煙用的包裝紙可被製作成具有附加材料之圖案，以降低使用包裝紙製作之吸煙用品的引燃傾向之特性。降低引燃傾向之特性係表示：當吸煙用品不小心在未注意的情況下被留置在底材上時，可以降低吸煙用品引起底材燃燒的能力。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.

依照本發明，可以將含有水性澱粉溶液之附加材料的預設圖案施用於包裝紙的基網。預設圖案可包括多個橫向帶狀紋、多個縱向帶狀紋、被處理區域的二維陣列或任何其它適合的圖案。這些預設圖案較佳係利用印刷技術來施用，例如凹版印刷、平版印刷、噴墨印刷、噴塗、模印等。最佳可使用凹版印刷。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.

為了改善由包裝紙所製成之吸煙用品之引燃傾向的特性，較佳是將含有氧化澱粉之印刷溶液施用於圖案上。較佳的印刷特性可以利用水性澱粉溶液來達成，其室溫黏度不大於約50 mPa‧s(厘泊,cP)，並且較佳是由乾燥時為約4至約40微米之粒子所製得，同時約有90%的粒子在潮濕時為約10至約100微米的範圍內。此外，澱粉溶液最好能夠是微酸性，pH值在約6至約6.5的範圍內。用於印刷溶液 的澱粉較好是與水混合，以形成一種具有約20%至約24%(重量%)澱粉濃度的印刷溶液。印刷溶液的另一項期望的特性是相當高的表面張力，例如，6.5×10-2 Nm-1 (65達因/公分)或更高的等級。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.

如有需要，印刷溶液可以二層或以上施用於基網。這些層可以彼此垂直對齊、彼此偏移、有些部分彼此有間隔‥等。此外，如有需要，可在一或多層的薄層中含有傳統的填料，如碳酸鈣。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.

一般而言，可以將附加材料的預設圖案施用於包裝紙的基網，以獲得改進的引燃傾向("IP")特性，以及獲得改進的自熄("SE")特性。引燃傾向是一種標準測試，其係依照ASTM E 2187-04所提出”測量吸煙用品之燃燒強度之標準測試方法”的方式來進行，其藉由引用而完全併入本文參照。引燃傾向係量測當吸煙用品被置放在底材上時，吸煙用品將產生足夠熱量以維持菸絲桿靜態燃燒的機率。期望能有低的IP值，因為這樣的數值代表悶燒吸煙用品造成下方底材燃燒的可能性較低。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.

此外，附加材料的預設圖案通常是施用於所具有之滲透率介於約20至約80 CORESTA單元範圍內的基網。當乾燥時，附加材料通常會在基網上形成一層薄膜，其可有效的局部降低滲透率，使該數值介於0至約10 CORESTA單元範圍內。在一些應用上，這種附加材料係以包含澱粉之水溶液的形式來施用。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.

吾人意外地發現，當圖案化的原紙被製成吸煙用品時 ，澱粉材料的某些特性可使得預設圖案產生非常低的引燃傾向值。更令人驚訝的瞭解是：在某些知名澱粉材料的標準規格中，材料性質在每批之間的變動會影響到所得吸煙用品之引燃傾向。舉例來說，由國家澱粉＆化學品公司所提供之Flo-Max 8氧化樹薯澱粉商品之規格可得知1%溶液的pH值是介在4.5至6.5的範圍內，而粒子的分子量則是超過10,000。令人驚訝的，當以pH值介在約6至6.5之範圍內的Flo-Max 8批料將預設圖案施加於基網時，與其它pH值約小於6但仍在製造商規格範圍內的Flo-Max 8其之批料相比，其引燃傾向已被發現有非常明顯的改善。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.

在薄膜施用於包裝紙時所選用的澱粉參數將會需要有各種不同的均衡或交換的考量。舉例來說，雖然高分子量的澱粉可以有效降低滲透率，但此種高分子量的澱粉只能以低濃度來使用，因而導致溶液具有非常高的水含量。但是水含量高的薄膜很難在多孔的包裝紙上有效地被乾燥。此外，已發現澱粉溶液的表面張力會影響小氣泡的滯留一低表面張力可使得較小的氣泡停留在溶液中，但是高表面張力則會使氣泡集結並且自溶液中分離出來，而產生可施用於包裝紙之更均勻且一致的材料。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.

雖然不是完全了解原因，但氧化澱粉的較佳pH範圍相信應會造成澱粉聚合物鏈的氧化程度較低--或較不完全，而產生比更酸(亦即較低pH值)之澱粉還要更多、更長的聚合物鏈。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.

此外，較長的聚合物鏈可產生具有較高黏度的溶液。當較高黏度之澱粉溶液在印刷方法中被施用於包裝紙時， 可以得到較佳的控制結果。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.

基於這些瞭解，研究結果發現：對於具有特殊和改良特性的澱粉溶液所形成之圖案化包裝紙而言，其在引燃傾向方面有明顯的改善。含有氧化澱粉之水溶液的特性包括：pH值在約6至約6.5的範圍內；表面張力至少為約6.5×10-2 Nm-1 (65達因/公分)；室溫黏度不大於約50 mPa‧s；並且乾燥粒子的粒徑分佈是在約4至約40微米的範圍內，而在潮濕時大約有90%的粒子在10至約100微米的範圍內。此外，粒子所具有的分子量較好是能使溶液所具有的澱粉濃度在約20%至約24%的範圍內。較佳的是，澱粉能包含氧化樹薯澱粉。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.

施用於基網或包裝紙之水性澱粉溶液通常是藉由製造澱粉/水混合物而製得，其係首先將所需重量的乾燥澱粉粉末與所需重量的室溫水(亦即在約15℃至約25℃)混合在一起，以獲得具有預設濃度之澱粉/水混合物。例如，要製備一種預設濃度為20%的澱粉/水溶液，須將20重量份的澱粉與80重量份的水混合。接著將澱粉/水溶液在約90℃至約95℃的升高次沸騰溫度範圍內(亦即低於沸點的溫度)加熱。使澱粉/水溶液維持在此高溫約20至約30分鐘以使其均熱。接著將澱粉/水溶液冷卻至室溫。冷卻步驟可以被動的方式來進行，例如藉由自然發生的熱傳方法；或者是冷卻步驟以主動(強制)的方式來進行，例如藉由浸入冷卻浴液或者是使用傳統的機械冷卻系統。在攪拌步驟、加熱步驟、均熱步驟和冷卻步驟的整個過程中須攪拌澱粉/水混合物。攪拌可以是連續或是實質上連續的。如果有 額外的成分，如碳酸鈣，要摻入澱粉/水溶液之中時，那些成分必需在澱粉/水溶液於均熱步驟之後並回復到室溫以後再添加。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.

具有上述所列特性且依前述方式來製備的水性澱粉溶液可以利用許多印刷技術中的任一種方法施用於基網上，包括(僅為舉例而非加以侷限)由凹版印刷、平版印刷、噴墨印刷、噴塗和模印所構成之組群。其它印刷方法也可能適合使用，並且可列入本專利申請書所教示的範圍內。然而，較佳係使用凹版印刷將澱粉溶液施用至基網上，以獲得一種圖案化的包裝紙。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.

例如(請參考第1圖)，將包裝紙的基網10由筒管12送出至凹版印刷系統14，在該處將依照前述說明所製備之澱粉溶液的預設圖案施加於基網10。具有新施加預設圖案的基網10係在收集筒管16之上收集。在其它的傳統步驟中，圖案化包裝紙的筒管16可用來製作用於製造吸煙用品(例如香煙)之菸絲桿。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.

凹版印刷系統14可包括一、二、三或更多個印刷器操作14a、14b、14c。這些操作基本上是相同的，描述其中一個的細節即足以了解其它操作的相對應細節。上述的澱粉溶液可以供料至貯液槽20，再由它抽送或以其它方式供應到具有圖案化表面的凹版印刷輥筒22。該輥筒22在澱粉溶液的浴液中滾動。當凹版印刷輥筒22滾動時，澱粉溶液會被刮刀組合23自輥筒表面擦去，因此當凹版印刷輥筒22與基網10在凹版印刷輥筒22和彈性包覆之逆向輥筒24 之間的壓印線接觸時，澱粉溶液可將凹版印刷輥筒22之表面上的圖案轉移到基網。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.

在經過適當的乾燥之後，可以將基網10送去進行一或多項其它的印刷操作14b、14c，在該處可將一或多層額外的澱粉材料以相同或不同的預設圖案施用於基網10。如有需要，在其它印刷操作中的澱粉材料可包含其它成分，例如碳酸鈣。此外，如有需要，可將含有碳酸鈣的澱粉溶液施用第一印刷操作14a中，同時將不含碳酸鈣的澱粉溶液施用於第二或後續的印刷操作14b、14c中。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.

基網10(請參考第2圖)通常具有橫向或跨網方向(以箭號30來標示)以及縱向(以箭號32來標示)。附加材料的預設圖案可包括多個橫向的(一般是平行的)區域或帶狀紋34。這些帶狀紋可沿著基網10的長度方向上均勻地間隔，或者是在菸絲桿長度和香煙成品的製造物的方向上以重覆出現的間隔性圖案來安排。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.

或者是，基網10可包括例如一或多個附加材料之縱向延伸區域或條紋36的預設圖案(請參考第3圖)。如有需要，預設圖案也可包含附加材料的二維陣列區域38(請參考第4圖)，其係沿著基網10和/或橫跨基網分隔開來。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.

此外，如前所述，附加材料可以施用於二層或以上的薄層40、42中(請參考第5圖)。如有需要的話，這些薄層可以彼此之間完全對齊並且有共同空間。或者是，上層42可以劃分或切割成兩個部分42a、42b，每一個皆是疊置在第一層或下層40之上，而在兩個部分42a、42b之間存在了一個空間。此空間可以在基網10的縱軸方向或者是橫軸 方向上延伸。又或者是，上層42可疊置在下層40之上，但是其間沒有共同空間。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.

吸煙用品(請參考第6圖)包含了菸絲桿205和濾嘴207，其係藉由濾嘴紙209而彼此連接在一起。菸絲桿205包括依照本發明所教授構成的包裝紙210。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.

當”大約”乙詞連同數值一起被用於本專利申請書中時，其係表示所伴隨的數值將包括所陳述數值再加上±10%的容差。此外，當本發明申請書中提及到百分比時，其係表示以重量為基準的百分比，亦即重量百分比。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.

很明顯地，在本發明申請書中已充份詳細的描述了一種新的、改良的且非顯而易見的方法，其係用於製造圖案化包裝紙之方法，對於在此技術領域具有通常技術能力者當可了解。此外，對於習於本技術領域者而言，可以明顯的看出本發明之特性存在了許多不同的修改、變異、取代及等效的作法，而不會實質偏離本發明的精神和範疇。因此，所有如同申請專利範圍中所定義之此類落於本發明之精神和範疇內的修改、變異、取代及等效作法皆明確被視為包含在本發明申請專利的範圍內。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.
