Abstract
A film is provided for use in a cassette. Preferably, the cassette is used in a waste disposal system. The film is a high density polyethylene film resin having both a low melt index and a high density, thereby providing improved odor control capabilities and enhanced tear strength and assembly strength.
Claims22
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.

- depositing waste into said tubing;
- and
- manipulating said tubing into discrete areas of enclosure for said waste.
