ABSTRACT:
A ventilated filter for a smoking product, particularly a smoking tobacco product, is provided by adhering inherently porous tipping wrap to inherently porous plug wrap by a multiplicity of randomly positioned, nonporous discrete areas of adhesive, thus leaving open areas for the air to enter the filter. Production of the porous filter can be accomplished by observing proper adhesive viscosities and solids weight content and by ensuring the adhesive is applied on the applicator in a film having the appropriate depth and on the tipping paper in the appropriate amount per unit area.
