Abstract

Bags or liners having incorporated therein an effective amount of odor management agents including a counteractant agent, a neutralizing agent and optionally, a masking agent, whereby the odor management agent imparts no perceptible scent to the bags or liners, such that the bags or liners are substantially free of fragrance while the odor management agent reduces malodor emanating from products disposed within the bag. Further, the invention is drawn to web materials for use in forming the bags or liners having odor management agents. The odor management agent is disposed within the bag or dispersed substantially uniformly throughout the web.

Claims (22)

1. A bag having odor management capabilities, the bag comprising:

a pair of opposing body panels joined together along a pair of opposing sides, and a bottom bridging the sides; and

an odor management agent distributed in at least one of the body panels for release into an interior of the bag to substantially reduce malodors emanating from products disposed within the bag,

wherein the odor management agent comprises a counteractant; and

wherein the bag is substantially free of fragrance.

2. The bag of claim 1 , wherein the counteractant is selected from the group consisting of 1-cyclohexyl-1-ethyl formate, 1-cyclohexyl-1-ethyl acetate, 1-cyclohexyl-1-ethyl proprionate, 1-cyclohexyl-1-ethyl isobutyrate, 1-cyclohexyl-1-ethyl n-butyrate, 1-cyclohexyl-1-propyl acetate, 1-cyclohexyl-1-propyl n-butyrate, 1-cyclohexyl-2-methyl-1-propyl acetate, 2-cyclohexyl-2-propyl acetate, 2-cyclohexyl-2-propyl propionate, 2-cyclohexyl-2-propyl isobutyrate, 2-cyclohexyl-2-propyl n-butyrate, 1-cyclohexylethan-1-yl acetate, 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-ol, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate, 2′-hydroxyl-1′-ethyl(2-phenoxy)acetate.

3. The bag of claim 1 , wherein the odor management agent is distributed substantially uniformly throughout the at least one of the body panels.

4. The bag of claim 1 , wherein the odor management agent is activated by humidity or by contact with an aqueous solution or liquid.

5. The bag of claim 1 , wherein the odor management agent is activated by contact with the products disposed within the bag.

6. The bag of claim 1 , wherein the at least one body panel comprises a first layer and a second layer, the odor management agent distributed in one of the first layer and the second layer.

7. The bag of claim 1 , wherein the at least one body panel comprises a first layer and a second layer, the odor management agent distributed in one of the first layer and the second layer, and the other of the first layer and second layer is a barrier material.

8. The bag of claim 1 , wherein the at least one body panel comprises a first layer and a second layer, the odor management agent distributed in one of the first layer and the second layer, and the other of the first layer and second layer is a diffusion layer.

9. The bag of claim 1 , wherein the odor management agent further comprises a neutralizing agent.

10. The bag of claim 9 , wherein the neutralizing agent is selected from the group consisting of lauryl methacrylate, a biguanide, a quaternary ammonium compound, an ester of unsaturated monocarboxylic acid, an uncomplexed cyclodextrin, a zinc ricinoleate compound, and an alkoxylated amine having the formula R(nAO) s NH t , wherein R is a saturated or unsaturated, linear or branched alkyl containing from 8 to 22 carbon atoms, AO is a C 2 -C 6 alkoxylate, n is the number of moles of AO and is from 1 to 50, s is 1, 2 or 3, t is 0, 1 or 2, and the sum of s and t is 3.

11. The bag of claim 10 , wherein the neutralizing agent is a zinc ricinoleate compound.

12. The bag of claim 9 , wherein the counteractant is loaded in the at least one of the body panels at about 0.05% to 5% (wt), and the neutralizing agent is loaded in the at least one of the body panel at about 0.005% to 0.5% (wt).

13. A bag having odor management capabilities, the bag comprising:

a pair of opposing body panels joined together along a pair of opposing sides, and a bottom bridging the sides; and

an odor management agent associated with at least one of the body panels for release into an interior of the bag to substantially reduce malodors emanating from products disposed within the bag,

wherein the odor management agent comprises a counteractant and a neutralizing agent; and

wherein the bag is substantially free of fragrance.

14. The bag of claim 13 , wherein the association is by being distributed in at least one of the body panels for release into an interior of the bag.
