Abstract

With the present invention a tobacco sheet or foil is proposed which has an elevated filling force and consists of tobacco particles, water, binders and moisturizers, and relatively gas-impermeable, in particular surface-sealed cover layers being connected together by a spongy structure which is formed by gas-filled bubbles, and in which cavities are formed having a shaggy, furrowed and/or torn surface.
