Abstract

Methods for encasing bodies including smokeless tobacco or a tobacco substitute with a polymeric casing can include coating a compressed body with microfibers, applying tubular casings to compressed bodies, printing netting and webs on compressed bodies, injection molding around compressed bodies, applying a webbing to compressed bodies, placing compressed bodies into a skin forming bath, and including thermoplastic polymers in a compressed body.

Claims (11)

1. A method of making a polymer encased smokeless tobacco or tobacco substitute product comprising:

forming a compressed body including smokeless tobacco, a tobacco substitute, or both smokeless tobacco and a smokeless tobacco substitute;

placing the compressed body in a mold cavity having dimensions closely approximating a shape and size of the compressed body;

injecting polymeric material around the compressed body in the mold cavity to form a webbing around the compressed body; and

curing the webbing to form an encased body.

2. The method of claim 1 , wherein the polymeric material injected around the compressed body is foam.

3. The method of claim 1 , further comprising:

depositing a dissolvable material on select portions of the compressed body before placing the compressed body in the mold cavity, wherein the dissolvable material at least partially contacts walls of the mold cavity.

4. The method of claim 3 , further comprising removing the dissolvable material from the encased body to produce pores in the webbing.

5. The method of claim 3 , wherein the dissolvable material is configured to dissolve in a mouth of an adult tobacco consumer.

6. The method of claim 5 , wherein the dissolvable material comprises a flavorant.
