What is claimed is: 1. A method of controlling odor in a disposal system comprising: providing a cassette having a non-resilient flexible tubing, said tubing being positioned in an annular space of said cassette, said tubing comprising a mono-layer high density polyethylene film resin with an Elmdorf tear strength in the range of 9 g to 20 g in the mold direction and in the range of 30 g to 400 g in the direction transverse to the mold direction, a melt index in the range of 0.1 g/10 min to 0.50 g/10 min and a density in the range of 0.90 g/cm3 to 0.99 g/cm3; depositing waste into said tubing; and manipulating said tubing into a discrete area of enclosure for said waste. 2. The method of claim 1, wherein said film has an organic permeant transmission rate of less than about 3.3횞106 μl/m 2-day, said organic permeant transmission rate being measured based upon transmission of 1-pentanethiol, valeric acid, p-cresol and indole. 3. The method of claim 1, wherein said density is about 0.90 g/cm3. 4. The method of claim 1, wherein said film has a tensile strength at break in a mold direction of 7,000 psi to 13,000 psi. 5. The method of claim 1, wherein said film has a tensile strength at break in a transverse direction of 6,000 psi to 10,000 psi. 6. The method of claim 1, wherein said film has an elongation at break in a mold direction of 250% to 500%. 7. The method of claim 1, wherein said film has an elongation at break in a transverse direction of 300% to 700%. 8. The method of claim 1, wherein said tubing has a thickness in the range of 7 μm to 30 μm. 9. The method of claim 1, further comprising adding a colorant to said film. 10. The method of claim 1, further comprising adding a deodorant to said film. 11. The method of claim 1, further comprising adding a fragrance to said film. 12. A method of controlling odor in a disposal system comprising: providing a cassette having a non-resilient flexible tubing, said tubing being positioned in an annular space of said cassette, said tubing comprising a mono-layer high density polyethylene film resin with an Elmdorf tear strength in the range of 9 g to 20 g in the mold direction and in the range of 30 g to 400 g in the directrion transverse to the mold direction, a low melt index and a high density, wherein said flexible tubing has an organic permeant transmission rate of less than about 3.3횞106 μl/m2-day, said organic permeant transmission rate being measured based upon transmission of 1-pentanethiol, valeric acid, p-cresol and indole; depositing waste into said tubing; and manipulating said tubing into discrete areas of enclosure for said waste. 13. The method of claim 12, wherein said melt index is in the range of 0.1 g/10 min to 0.50 g/10 min. 14. The method of claim 12, wherein said density is in the range of 0.90 g/cm3 to 0.99 g/cm3. 15. The method of claim 12, wherein said film has a tensile strength at break in a mold direction of 7,000 psi to 13,000 psi. 16. The method of claim 12, wherein said film has a tensile strength at break in a transverse direction of 6,000 psi to 10,000 psi. 17. The method of claim 12, wherein said film has an elongation at break in a mold direction of 250% to 500%. 18. The method of claim 12, wherein said film has an elongation at break in a transverse direction of 300% to 700%. 19. The method of claim 12, wherein said tubing has a thickness in the range of 7 μm to 30 μm. 20. The method of claim 12, further comprising adding a colorant to said film. 21. The method of claim 12, further comprising adding a deodorant to said film. 22. The method of claim 12, further comprising adding a fragrance to said film.
