Q.1018: Why cigarette wrapping paper does not burn as fast as normal paper?

Ans. One of the objective of cigarette paper is to match its burning rate with that of tobacco. CaCO3 (Calcium Carbonate), a filler used in cigarette tissue retard burning rate of paper. Other reason of adding Calcium Carbonate to paper is that, on burning, CaCO3 produces Carbon dioxide (CO2) and CaO. CO2 is harmless when inhale.

To match burning rate more preciously, other chemicals are added in the paper.
