  • Smoking rod wrapper and compositions for their production
    Patent number: 4889145

  • Process for producing smoking rod wrapper and smoking rod containing same
    Patent number: 4784163
    Abstract: A printing ink comprises a liquid vehicle, containing a binder, and a smoke-enhancing additive in the form of particles that are insoluble in the liquid vehicle and that have sizes in the range 5-80 microns, preferably at least 90% of the particles having sizes in the range 10-50 microns. The inks are printed onto the inner surface of a smoking rod wrapper in amounts such that the weight of dry deposits is in the range 20 to 60 mg per wrapper.

  • Smoking rod wrappers and compositions for their production
    Patent number: 4784164
    Abstract: A smoking rod wrapper material has porosity apertures which are partially or fully blocked by a coating of a heat-removable, porosity-reducing composition. The composition melts as the burning tip of the smoking rod approaches to increase the porosity of the wrapper.
