Abstract

The tobacco products incorporate binder systems. The binder systems possess or exhibit thermoplastic properties, characteristics or behaviors. The binder system can incorporate at least one type of binding agent that exhibits thermoplastic properties (e.g., the binding agent can be composed of at least one thermoplastic polymeric material). Additionally, the binder system can incorporate ingredients or materials so as to provide a binding agent that exhibits thermoplastic characteristics (e.g., the binding agent can be composed of at least one thermoplastic binding material in combination with a plasticizer). Tobacco products are produced by contacting tobacco, together with other desired ingredients, in the presence of a binder system, and forming (e.g., by extrusion) the resulting mixture into a shape. Of particular interest are processing conditions that most preferably involve exposing a tobacco formulation to a temperature of less than about 100° C. during processing conditions (such as those experienced during extrusion), that involve use of a binding agent that can be employed in relatively low amounts, that involve use of a binding agent that exhibits desirable thermoplastic behavior (and hence can act to provide good physical integrity to the formed tobacco product) at processing conditions of less than about 100° C., and that involve the use of relatively low to moderate amounts of liquid processing aids (e.g., water or other liquid carriers).
