摘要：
The present invention is generally directed to low weight cigarette wrapping papers. In particular, the wrapping papers, although having a low basis weight, have an opacity of at least 70% and a tensile strength comparable with conventional papers. Wrapping papers made according to the present invention contain a white pigment having a medium particle size of from 0.1 microns to about 0.5 microns. In one embodiment, a black pigment can also be combined with the white pigment in small amounts.
