SMOKING ARTICLE (VARIANTS), A PAPER WRAPPER FOR THE SMOKING ARTICLE, WHICH HAS TREATED AREAS FOR REDUCING IGNITION PROCLIVITY CHARACTERISTICS, AND A METHOD TO FORM THEREOF

摘要

Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a paper wrapper containing cellulosic fibers and filler particles. The paper wrappers are formed so that the filler particles form a concentration gradient throughout the thickness of the wrapper. More particularly, a greater concentration of filler particles are present at a first surface in comparison to the amount of filler particles present at the opposite surface. In accordance with the present disclosure, an ignition reducing composition is applied to the first surface, in this manner, treated areas having more uniform properties are formed.
