ABSTRACT:
The present invention is directed to a tipping paper adapted for wrapping a filter of a smoking article. The tipping paper contains a pigment made from calcium carbonate particles having a median size of between about 0.1 microns to about 0.5 microns. The calcium carbonate pigment can be used to create a tipping paper having an opacity of up to at least 89%. In comparison to conventional tipping papers, it has been surprisingly discovered that the tipping paper of the present invention reduces knife wear of a cutting instrument used to cut the paper and is less retentive to solvents when the paper is printed with a solvent based ink or covered with a solvent based coating.
