PAPER WRAPPER FOR REDUCTION OF CIGARETTE BURN RATE

摘要

A method of reducing the burn rate of a smoking article is provided. Specifically, the burn rate is reduced by incorporating into a paper wrapper of the smoking article a filler (e.g., precipitated calcium carbonate) having a median particle size greater than about 2.5 microns. For instance, such paper wrappers formed according to the present invention typically have a Diffusion Conductance Index (DCI) of less than about 15 cm-1 and a Static Burn Rate (SBR) of less than about 5 millimeters per minute.
