Abstract

A melt-blown fabric for pouching smokeless tobacco or a smokeless tobacco substitute can include melt-blown polymer fibers. The fabric can have a basis weight of less than 10 gsm and a tensile strength of at least 4 mJ in at least one predetermined direction. Method of making the fabric can include melt-blowing a polymeric material against a support surface and bonding the fibers or arranging them in a predetermined orientation. Pouched smokeless tobacco or tobacco substitute products including the fabrics provided herein can provide desirable flavor and tactile experience.

Claims

1. A smokeless tobacco product comprising:

a pouch including,

a non-woven fabric including a polymer and a colorant, the colorant being configured to increase a hydraulic permittivity of the non-woven fabric, the non-woven fabric having a basis weight ranging from about 10 grams per square meter (gsm) to about 30 gsm; and

smokeless tobacco within the pouch.

2. The smokeless tobacco product of claim 1, wherein the non-woven fabric includes a plurality of fibers, the plurality of fibers including the polymer.

3. The smokeless tobacco product of claim 2, wherein the polymer is mouth-stable.

4. The smokeless tobacco product of claim 2, wherein the polymer includes an elastomer.

5. The smokeless tobacco product of claim 2, wherein the polymer includes polyurethane.

6. The smokeless tobacco product of claim 2, wherein at least a portion of the fibers of the plurality of fibers have a diameter of less than about 30 microns.

7. The smokeless tobacco product of claim 2, wherein the plurality of fibers includes melt-blown fibers.

8. The smokeless tobacco product of claim 1, wherein the smokeless tobacco has an average length ranging from about 0.1 inches to about 1 inches and an average width ranging from about 0.009 inches to about 0.1 inches.

9. The smokeless tobacco product of claim 1, wherein the smokeless tobacco includes cured tobacco.

10. The smokeless tobacco product of claim 1, wherein the smokeless tobacco product has an overall oven volatiles content ranging from about 4 percent by weight to about 61 percent by weight.

11. The smokeless tobacco product of claim 10, wherein the smokeless tobacco product has an overall oven volatiles content ranging from about 30 percent by weight to about 61 percent by weight.

12. The smokeless tobacco product of claim 11, wherein the smokeless tobacco product has an oven volatiles content ranging from about 50 percent by weight to about 60 percent by weight.

13. The smokeless tobacco product of claim 1, further comprising:

a flavorant.

14. The smokeless tobacco product of claim 1, wherein the colorant comprises a brown colorant.

15. A pouch for a pouch product, the pouch comprising:

a non-woven fabric including polyurethane and a colorant, the colorant being configured to increase a hydraulic permittivity of the non-woven fabric, the non-woven fabric having a basis weight ranging from about 10 grams per square meter (gsm) to about 30 gsm.

16. The pouch of claim 15, wherein the non-woven fabric includes a plurality of fibers, the plurality of fibers including the polyurethane and the colorant.

17. The pouch of claim 16, wherein at least a portion of the fibers of the plurality of fibers have a diameter of less than about 30 microns.

18. The pouch product of claim 15, wherein the colorant comprises a brown colorant.

19. A non-tobacco product comprising:

a pouch including,

a non-woven fabric including a polymer and a colorant, the colorant being configured to increase a hydraulic permittivity of the non-woven fabric, the non-woven fabric having a basis weight ranging from about 10 grams per square meter (gsm) to about 30 gsm; and

a non-tobacco cellulosic mixture within the pouch.

20. The non-tobacco product of claim 19, wherein the polymer comprises a mouth-stable elastomer.

21. The non-tobacco product of claim 20, wherein the mouth-stable elastomer comprises polyurethane.
