Cigarette paper has a dynamic interaction with the cigarette tobacco column. Ion exchanges occur between the tobacco column and cigarette paper during cigarette ageing. Previous reports have discussed ion transfer from the tobacco column to conventional cigarette paper. This presentation will review and report on ion transfer from the tobacco column to cigarette paper with bands applied to the paper to provide >75%SE on the ASTM test method E2187-09. Cigarettes with American type and special blends will be investigated to identify if there are any differences and levels of ion transfer. In addition diffusion of base and bands will be investigated. The influence of these ions on base paper and band diffusion under lab conditions (23 °C and 50%RH) and after heating to 230 °C for 30 minutes will also be discussed.

Preliminary investigations showed that band diffusion after heating at high temperature for papers removed from the cigarette after ageing is different than control papers (not taken from cigarette).
