Tobacco product wrapping material with controlled burning properties

A method for the production of a tobacco product wrapping material, wherein the method comprises:

• forming a pulp suspension, wherein the pulp suspension comprises a cellulose pulp and composite particles, wherein the composite particles are obtained according to a method comprising:
• (a) preparing an aqueous suspension containing calcium carbonate particles;
• and
• (b) adding a metal salt to the aqueous suspension, wherein the metal salt comprises an aluminum cation, and further wherein the metal salt:
• (i) forms a basic metal component in the suspension;
• and
• (ii) has a solubility of greater than 9.0 mg/L, in water, measured at the pH value of the prepared suspension and at a temperature of 20° C.;
• draining the pulp suspension;
• and
• drying the pulp suspension.

A tobacco product, characterized in that it comprises a tobacco product wrapping material comprising composite particles obtained according to a method comprising:

• (a) preparing an aqueous suspension containing calcium carbonate particles;
• and
• (b) adding a metal salt to the aqueous suspension, wherein the metal salt comprises at least one aluminum nitrate, polyaluminum chloride, and aluminum nitrate sulfate, and further wherein the metal salt:
• (i) forms a basic metal component in the suspension;
• and
• (ii) has a solubility of greater than 9.0 mg/L in water, measured at the pH value of the prepared suspension and at a temperature of 20° C.

A method for the production of a tobacco product wrapping material, wherein the method comprises:

• forming a cellulose pulp suspension;
