Abstract

The invention features a single film construction with two distinctly different surface characteristics for a trash compactor bag composite. The high slip interior layer integrally bonded to a tacky carbon outside layer forms a moisture proof, odor adsorbing trash compactor refuse receptacle. The construction may be made of biodegradable plastic.

Claims

1. A refuse bag for a trash compactor, said trash compactor including an inner wall, said refuse bag comprising a flexible envelope, said envelope including a unitary wall, said unitary wall comprising an inner layer and outer layer, said inner and outer layer integrally formed of plastic fabricated by blow film coextrusion while said plastic is in a liquid state, said unitary wall having a size selected to engage the inner wall of said trash compactor, said inner layer of said wall having a slippery surface, and said outer layer of said wall containing carbon and having a tacky surface, whereby said outer layer'"'"'s tacky surface is adapted to non-slidably engage said inner wall of said trash compactor and also adsorb odor.

2. The refuse bag of claim 1, wherein said inner layer comprises a polyethylene plastic.

3. The refuse bag of claim 1, wherein said odor adsorbing outer layer comprises a carbon-containing polyethylene plastic.

4. The refuse bag of claim 3, wherein said carbon-containing polytheylene plastic comprises carbon by weight in an approximate range of from one to ten per cent.

5. The refuse bag of claim 3, wherein said carbon-containing polyethylene plastic comprises carbon by weight in an approximate range of from ten to twenty per cent.

6. The refuse bag of claim 2, wherein said odor adsorbing outer layer comprises a carbon-containing polyethylene plastic.

7. The refuse bag of claim 1, wherein said inner layer has a thickness in a range from approximately one to four mils.

8. The refuse bag of claim 1, wherein said outer layer has an approximate thickness in a range from one to four mils.

11. The refuse bag of claim 1 including at least one gusset.

9. A refuse bag for a trash compactor, said trash compactor including an inner wall, said refuse bag comprising a flexible envelope, said envelope including a unitary wall, said unitary wall comprising an inner layer and outer layer, said inner and outer layer integrally formed of plastic fabricated by blow film coextrusion while said plastic is in a liquid state, said unitary wall having a size selected to engage the inner wall of said trash compactor, said inner layer of said wall including material imparting a slippery surface to said wall, said outer layer of said wall containing carbon, and said outer layer further including material imparting a tacky surface to said wall, whereby said outer layer'"'"'s tacky surface is adapted to non-slidably engage said inner wall of said trash compactor and also adsorb odor.

10. In combination with a trash compactor a refuse bag, said refuse bag comprising a flexible envelope, said envelope including a unitary wall, said unitary wall comprising an inner layer and outer layer, said inner and outer layer integrally formed of plastic fabricated by blow film coextrusion while said plastic is in a liquid state, said inner layer of said wall having a slippery surface, said outer layer of said wall containing carbon and having a tacky surface, and said outer layer of said wall engaging the inner wall of said trash compactor, whereby said outer layer'"'"'s tacky surface non-slidably engages said bag at said inner wall of said trash compactor and also adsorbs odor.

12. In combination with a trash compactor a refuse bag, said refuse bag comprising a flexible envelope, said envelope including a unitary wall, said unitary wall comprising an inner layer and outer layer, said inner and outer layer integrally formed of plastic fabricated by blow film coextrusion while said plastic is in a liquid state, said inner layer of said wall including material imparting a slippery surface to said wall, said outer layer of said wall containing carbon, and said outer layer further including material imparting a tacky surface to said wall, and said outer layer of said wall engaging the inner wall of said trash compactor, whereby said outer layer'"'"'s tacky surface non-slidably engages said bag at said inner wall of said trash compactor and also adsorbs odor.
