Rolling paper for non-combustion-heating-type smoking product, non-combustion-heating-type smoking product, and electric-heating-type smoking system

Abstract

Provided is rolling paper for a non-combustion-heating-type smoking product, the rolling paper having a section in which a heat-sensitive material is added on a surface that serves as an outer circumferential surface of a non-combustion-heating-type smoking product, wherein a color difference ΔE* between the color of, before heating the rolling paper, the section in which the heat-sensitive material is added and the color of, after heating the rolling paper for five minutes at 200° C., the section in which the heat-sensitive material is added is 15 or greater.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of PCT International Application No. PCT / JP2018 / 017407, filed on May 1, 2018, which is hereby expressly incorporated by reference into the present application.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a wrapping paper for a non-combustion-heating-type smoking product, a non-combustion-heating-type smoking product, and an electric-heating-type smoking system.[0003]A non-combustion-heating-type smoking product of a type, in which heating is performed from the periphery of a tobacco rod including shredded tobacco and in which a volatile component is delivered to a user, is known. In the non-combustion-heating-type smoking product, the tobacco rod wrapped with a wrapping paper is heated, but unlike conventional cigarettes, the tobacco rod remains unburned after use (after heating).[0004]In conventional cigarettes, white (colorless) paper is generally used as a wr...

AI Technical Summary

Benefits of technology

The present invention provides a wrapping paper for a non-combustion-heating-type smoking product that does not show an unpleasant visual appearance due to heating. The goal is achieved by using a wrapping paper that has a section with a certain color difference after heating compared to before heating. This results in a more pleasant appearance of the smoking product and enhances the user's experience.

Problems solved by technology

It was found that, when a wrapping paper used in conventional cigarettes is used as a wrapping paper for wrapping shredded tobacco in non-combustion-heating-type smoking products, heating thereof during use may cause discoloration that is unpleasant to a user.

Paper made mainly of pulp burns and turns brown when heated at a certain temperature or higher, but since the change in color is caused physically due to thermal decomposition of pulp and paper constituent components, it is not possible to simply prevent such discoloration.

However, the inventors have found that, even if discoloration occurs due to burning, in order to prevent the discoloration from being recognized as an unpleasant color, by adding a specific heat sensitive material to the wrapping paper in advance so that a certain color difference or more occurs between before heating and after heating, the unpleasant discoloration can be made unapparent.
