Title (EN) BIODEGRADABLE CIGARETTE FILTER
(FR) FILTRE À CIGARETTE BIODÉGRADABLE
Abstract:
(EN) A biodegradable fiber (including fiber tow) and/or biodegradable paper substrate may be coated with cellulose acetate and/or plasticized cellulose acetate for use in a filter material configured for application in a filter of a smoking article. A filter made in accordance with this design may also include non-biodegradable material.
(FR) Selon l'invention, une fibre biodégradable (comprenant une mèche de fibre) et/ou un substrat de papier biodégradable peuvent être recouverts d'un acétate de cellulose et/ou d'un acétate de cellulose plastifié en vue d'être utilisés dans un matériau de filtre destiné à une utilisation dans un filtre d'article à fumer. Un filtre élaboré selon ce modèle peut également comprendre un matériau non biodégradable.
