Benefits of technology

The coating composition in this patent can make cigarettes last longer and have a nicer taste. It can also improve the viscosity and retention rate of the coating, increase the amount of coating on the cigarette, and make the coating process more efficient and cost-effective. Additionally, it can allow the coating to dry at room temperature and reduce the manufacturing time of the cigarettes.

Problems solved by technology

However, it may be less than 2 months to maintain the properties of the coating composition at 20° C. or more due to the inherent aging characteristics of the starch, and the service life may further be shortened because the aging occurs drastically when the coating composition is exposed to the low temperature.
In addition, such coating composition may reduce the low ignition performance at the high temperature drying, and it may be difficult to dry the coating composition coated on the cigarette paper at the room temperature drying.
In addition, such coating composition may have a large change in viscosity in a dynamic state such as rotation, such that a coating amount may decrease during coating, and the workability may decrease.

example 1

[0096]Arabic gum, maltose, ethanol, and water are weighed according to a mixing ratio, respectively, and water is mixed with ethanol to prepare a dispersion medium, and the temperature of the dispersion medium is maintained at about 30° C. through heating or cooling.

[0097]Maltose is dispersed in this dispersion medium at a unit dispersion amount of about 15 g / L / min by using an impeller at a rotational speed of about 18000 rpm. Arabic gum is then dispersed at a unit dispersion of about 15 g / L / min at a rotational speed of about 18000 rpm. At this time, the temperature of the composition may rise by the rotation, and the temperature is controlled so as not to exceed about 45° C.

[0098]Next, the composition is rotated at a speed of about 300 rpm by using a double cross-type impeller, so that the viscosity becomes uniform. The temperature of the homogenized mixture is then lowered to about 30° C. and the composition is rotated at a speed of about 200 rpm by using a homomixer.

Abstract

A coating composition for low ignition propensity cigarette paper, according to one embodiment of the present invention, comprises 10-30 wt % of gum arabic, 25-35 wt % of maltose, 15-30 wt % of ethanol and 10-40 wt % of water.

Description

TECHNICAL FIELD[0001]A coating composition for a low ignition propensity cigarette paper, a cigarette using the same, and a method for manufacturing a low ignition propensity cigarette paper are provided.BACKGROUND ART[0002]In general, in order to manufacture a tobacco, various kinds of leaf tobaccos are processed by blending them to the desired aroma and taste. The processed tobacco leaves are then carved out to produce cut tobacco leaves, which are surrounded by a cigarette paper to produce a filter-less cigarette. A filter is then attached to the filter-less cigarette as needed.[0003]The cigarette paper may be made of flax, wood pulp, and the like, which is required to maintain the combustibility and the taste of the tobacco when the cigarette paper is burned. The tobacco filter may include an activated carbon, a flavoring material, and the like, and may be composed of a mono-filter or a multi-filter, and the cigarette filter is surrounded by a cigarette filter wrapping paper.
