Abstract

Cigarette filters having satisfactory characteristics as regards strength under mechanical and pneumatic compressions as well as their efficiency for tar tetention, are produced by extruding a mixt of an open cell foamed thermoplastic resin of high density, e.g. polyethylene or polypropylene, the moulding being cut first into rods and then into lengths for the separate filters Chemically active agents for the partial or complete elimination of harmful substances are included as well as other cpds for imparting a flavour or aroma to the smoke.
