Abstract
A low ignition propensity wrapping paper includes a paper web and bands arranged on the web at predetermined intervals in a longitudinal direction of the web. These bands are formed by applying a combustion-inhibition liquid onto the web. The combustion-inhibiting liquid contains a solvent and a combustion inhibitor that is sodium alginate or pectin dissolved in the solvent. The solvent is treated water obtained by substantially removing at least calcium ions and magnesium ions from raw water of a water supply or a well.
