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.
Claims20
A cassette for holding waste in a waste disposal system, the cassette comprising:
- a body having a top, said body defining an annular space therein, said body being adapted to rotate in a container of the system a length of non-resilient flexible tubing positioned for use in a tight layer in said annular space, said tubing being a film having odor control capability for an amount of odiferous gas that penetrates said film, said tubing having high tear strength and being capable of being sealed, wherein said tubing is dispensed through the top of said body when said body rotates to seal said tubing thereby enclosing the waste, and wherein said film is formed of a high density polyethylene film resin with both a low melt index and a high density, wherein said tubing has an organic permeant transmission rate of less than about 3.3×106 μl/m2-day, said organic permeant transmission rate being measured based upon transmission of 1-pentanethiol, valeric acid, p-cresol and indole.
A cassette for holding waste in a waste disposal system, the cassette comprising:
- a body having a top, said body defining an annular space therein, said body being adapted to rotate in a container of the system, a length of non-resilient flexible tubing positioned for use in a tight layer in said annular space, said tubing being a film having odor control capability of an amount of odiferous gas that penetrates said film and high tear strength and capable of being sealed, wherein said tubing is dispensed through the top of said body when said body rotates to seal said tubing thereby enclosing the waste, wherein said film is formed of a high density polyethylene film resin with both a low melt index and a high density and wherein said tubing has a deodorant added thereto.
