Description

In this example, the columnar element 20 includes a fibrous filter material 25 that is coated on the entire circumference within a wrapping paper (in this case, a plug web) 26 and whose longitudinal ends are left uncoated. Yes. In alternative embodiments, the cylindrical element 20 may be formed in other ways. Alternatively, the columnar element 20 may be formed from other fiber materials and may be configured to have a different structure. The cylindrical element 20 may be formed, for example, from a rigid paper, plastic, card, or other material as an open or closed end hollow tube . Cylindrical element 20 also need not be coated with wrapping paper, but can also be formed without wrapping paper, such as uncoated acetate (NWA) plugs formed from cellulose acetate fibers. The fibrous filter material 25 is composed of cellulose acetate fiber and / or polyvinyl alcohol (PVOH), polylactic acid (PLA), polycaprolactone (PCL), poly (1-4 butanediol succinate) (PBS), poly Other materials used to form fibers, such as (butylene adipate-co-terephthalate) (PBAT), starch-based materials, paper, cotton, aliphatic polyester materials and polysaccharide polymers can be included.
