摘要： The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself. Specifically, it has been unexpectedly discovered that the ash characteristics of a paper wrapper are noticeably improved when a calcium carbonate filler having a median particle size of from about 0.15 microns to about 0.5 microns is incorporated into the paper. Paper wrappers made with the calcium carbonate particles of the present invention have superior ash characteristics in comparison to paper wrappers incorporating calcium carbonate particles of larger or smaller sizes. Further, the ash characteristics of the paper are improved without having to alter total filler levels in the paper.

摘要翻译： 本发明涉及一种用于改善吸烟制品的纸包装物的灰分特性并改善吸烟制品本身的灰分特性的方法。 具体地说，意外地发现当中等粒度为约0.15微米至约0.5微米的碳酸钙填料掺入纸中时，纸包装物的灰分特性明显改善。 与包含较大或较小尺寸的碳酸钙颗粒的纸包装纸相比，用本发明的碳酸钙颗粒制成的纸包装纸具有优异的灰分特性。 此外，纸的灰分特性得到改善，而不必改变纸中的总填料水平。
