Abstract

An apparatus for enrobing a product portion can include at least one polymer spray head adapted to create at least one flow of polymeric fibers to produce at least one polymer enrobing zone and a conveyor system adapted to move at least one product portion from at least one position below at least one polymer enrobing zone and to at least one position above at least one polymer enrobing zone to drop each product portion through one or more polymer enrobing zones a plurality times at different orientations to enrobe each product portion with polymeric fibers.

Claims (31)

1. An oral product comprising:

tobacco; and

a fiber wrap surrounding the tobacco, the fiber wrap being seamless and comprising a plurality of melt-blown fibers, the melt-blown fibers including,

a polymer, and

a colorant configured to increase a hydraulic permittivity of the fiber wrap.

2. The oral product of claim 1 , wherein the tobacco includes fibers having an average particle aspect ratio of greater than 3.

3. The oral product of claim 1 , wherein the tobacco has a total oven volatiles content ranging from 45% by weight to 65% by weight.

4. The oral product of claim 1 , wherein the polymer includes an elastomer.

5. The oral product of claim 4 , wherein the elastomer includes polyurethane.

6. The oral product of claim 1 , wherein at least a portion of the fibers of the plurality of melt-blown fibers have a diameter of less than 100 microns.

7. The oral product of claim 6 , wherein the diameter ranges from 0.5 microns to 5 microns.

8. The oral product of claim 7 , wherein the diameter is less than 1 micron.

9. The oral product of claim 1 , wherein the polymer is hydrophilic.

10. The oral product of claim 1 , wherein the polymer is mouth-stable.

11. The oral product of claim 1 , wherein the fiber wrap further includes a filler, the filler being configured to increase the hydraulic permittivity of the fiber wrap.

12. The oral product of claim 1 , wherein the colorant includes a brown colorant.

13. The oral product of claim 1 , wherein the polymer is present in the oral product in an amount less than or equal to 200 mg.

14. An oral product comprising:

non-tobacco cellulosic fibers; and

a fiber wrap surrounding the non-tobacco cellulosic fibers, the fiber wrap being seamless and comprising a plurality of melt-blown fibers, the melt-blown fibers including,

a polymer, and

a colorant configured to increase a hydraulic permittivity of the fiber wrap.

15. The oral product of claim 14 , wherein the non-tobacco cellulosic fibers have an average particle aspect ratio of greater than 3.

16. The oral product of claim 14 , wherein the non-tobacco cellulosic fibers have a total oven volatiles content ranging from 45% by weight to 65% by weight.

17. The oral product of claim 14 , wherein the polymer includes an elastomer.

18. The oral product of claim 17 , wherein the elastomer includes polyurethane.

19. The oral product of claim 14 , wherein at least a portion of the fibers of the plurality of melt-blown fibers have a diameter of less than 100 microns.

20. The oral product of claim 14 , wherein the non-tobacco cellulosic fibers have a total oven volatiles content ranging from 10% by weight to 20% by weight.

21. The oral product of claim 14 , wherein the non-tobacco cellulosic fibers have a total oven volatiles content ranging from 25% by weight to 35% by weight.

22. The oral product of claim 14 , further comprising:

nicotine.
