Abstract
A single-segment filter having a filter plug uses a high-rigidity and high-permeability paper longitudinal rigidity of which is 30 or higher as measured in accordance with JIS P8143 and air permeability of which is 1000 CORESTA units or greater as a filter plug wrapper wrapping a filter material, and a multisegment filter having a plurality of filter plugs uses the high-rigidity and high-permeability paper as a filter plug wrapper wrapping a filter material and/or a shaping paper joining plurality of filter plugs. A cigarette comprises the particular filter.
Claims17
A cigarette filter comprising:
- a filter plug comprising a cylindrical body of a filter plug wrapper which is cylindrically shaped and a filter material disposed in the cylindrical body,
- wherein the filter plug wrapper is formed of a high-rigidity and high-permeability paper longitudinal rigidity of which is 30 or higher as measured in accordance with JIS P8143 and air permeability of which is 1000 CORESTA units or greater.
A cigarette filter comprising:
- a plurality of filter plugs comprising a most upstream filter plug and a most downstream filter plug, each comprising a cylindrical body of a filter plug wrapper which is cylindrically shaped and a filter material disposed in the cylindrical body;
- and
- a shaping paper configured to wrap the circumference of the plurality of filter plugs and join the plurality of filter plugs to each other,
- wherein the filter plug wrapper of at least one of the plurality of filter plugs is formed of a high-rigidity and high-permeability paper longitudinal rigidity of which is 30 or higher as measured in accordance with JIS P8143 and air permeability of which is 1000 CORESTA units or greater.
