Abstract
Abstract A composite structure for use on a smoking product including a non-porous tipping paper coated with a heat-activatable adhesive in a selected pattern, having areas void of adhesive and microscopic openings through the tipping paper within the void areas. The method of manufacturing the composite structure includes applying a non-conductive, heat-activatable adhesive coating on the paper web in a specific pattern having void and adhesive coated areas and forming perforations in the void areas of the paper web.
