More Information
Summary:A smoking article such as a cigarette has a rod of smoking material wrapped in a wrapper of which the substantially uniform air permeability due to viscous flow is not more than 3 and preferably not more than 2 Coresta Units and of which the Do/t value is in the range of 0.08 to 0.65 cm sec-1, preferably 0.15 to 0.25 cm sec-1. The length of the rod of smoking material may suitably be within a range of 25 to 55 mm. A reduction in sidestream TPM delivery of 40% or more can be obtained. The invention is also concerned with a smoking-article wrapper material which satisfies the above permeability and Do/t value requirements.
