Description

[0001] This application is a divisional application of the original Chinese patent application number 201580003693.2, the application date was October 15, 2015, and the invention name is "hydrophobic packaging material". technical field [0002] The present invention relates to paper for smoking articles wherein the wrapper has a hydrophobic surface and is used with a tobacco substrate having a higher degree of moisture. Background technique [0003] Combustible smoking articles, such as cigarettes, typically include a cylindrical rod of tobacco cut filler surrounded by wrapper material, and a cylindrical filter axially aligned in contiguous end-to-end fashion with the wrapped tobacco rod. Cylindrical filters typically comprise filter material defined by a mouthpiece segment wrapper. The wrapped tobacco rod and filter are joined by a strip of tipping wrap material, usually formed of paper material, which defines the entire length of the filter and the adjacent portion of the...
