The invention relates to a cigarette paper that has the following properties across at least one section of its surface: no artificial perforation; the air-permeability is at least 15 CU, preferably at least 20 CU and especially preferred at at least 25 CU; and for the exponent k, which is measured with a measurement head having a rectangular opening of 2 mm x 15 mm according to ISO 2965:2009, and which is defined as (I), with Q1: air flow through the paper at pressure difference p1 = 1.00 kPa, and Q2: air flow through the paper at pressure difference p2 = 0.25 kPa, the following applies: k < 0.98, preferably k <= 0.95 and especially preferred k <= 0.93, and k >= 0.8, preferably k >= 0.85. |
