Polymer encased smokeless tobacco products
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.
1. A method of making a polymer encased smokeless tobacco or tobacco substitute product, the method comprising:
forming a compressed body including smokeless tobacco, a tobacco substitute, or both the smokeless tobacco and the tobacco substitute;
applying an electrostatic charge to the compressed body to form a charged body;
coating the charged body with microfibers to form a microfiber-coated body, the microfibers including a polymeric material; and
heating the microfiber-coated body to melt bond the microfibers to form an encased body.
2. The method of claim 1 , wherein the coating the charged body with microfibers is performed in a chamber having circulating microfibers.
3. The method of claim 2 , wherein the coating the charged body with microfibers comprises:
carrying the charged body through the chamber on a conveyor.
4. The method of claim 3 , wherein the coating the charged body with microfibers comprises:
rotating, using the conveyor, the charged body.
5. The method of claim 4 , wherein the conveyor comprises at least two rods.
6. The method of claim 1 , wherein the coating the charged body with microfibers comprises:
rolling, tumbling, or both rolling and tumbling the charged body down a sloped surface, the microfibers being disposed on the surface.
7. The method of claim 6 , wherein the coating the charged body with microfibers further comprises:
vibrating the surface during the rolling, the tumbling, or both the rolling and the tumbling the charged body down the surface.
8. The method of claim 1 , wherein the charged body has less than about 10 weight percent oven volatiles during coating the charged body with microfibers.
9. The method of claim 8 , further comprising:
hydrating the encased body to form an encased product having greater than about 10 weight percent oven volatiles.
10. The method of claim 1 , wherein the heating the microfiber-coated body includes exposing the microfiber-coated body to infrared (IR), ultraviolet (UV), convection heat, or combinations thereof.
11. The method of claim 1 , wherein the polymeric material is selected from the group consisting of: polypropylene, polyurethane, styrene, and combinations thereof.
12. The method of claim 1 , wherein the polymeric material includes an elastomer and a polyolefin.
13. The method of claim 1 , wherein the compressed body further comprises a flavorant comprising wintergreen, cherry, berry, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cinnamon, cardamom, apium graveolens, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, Japanese mint, cassia, caraway, cognac, jasmine, chamomile, menthol, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, liquorish, mint oils from a species of the genus Mentha, a sub-combination thereof, or a combination thereof.
