Abstract
A cigarette paper contains pulp fibers and filler particles, whereby at least 20% of the filler particles, by mass or by particle number, have a flaked shape. The flaked filler particles have a length l, a width b and a thickness d, which correspond to the respective maximum extension in three mutually orthogonal spatial directions, whereby the length l as well as the width b are at least twice as large as the thickness d. The mass-specific median value d50 of the particle size distribution measured according to ISO 13317-3 is between 0.2 μm and 4.0 μm, and the flaked particles are formed by calcium carbonate.
