Abstract
Official abstract text for this publication.
The use of a palladium-doped zeolite for the adsorption of volatile organic compounds is described wherein the zeolite has a CHA framework type and is polymer-bound. Such zeolites have been found to have particular utility as packaging materials for the adsorption of volatile organic compounds, such as those originating from organic matter.
First claim
Opening claim text (preview).
What is claimed: 1. A packaging material for the adsorption of volatile organic compounds, wherein the packaging material comprises a coating on its surface, and wherein the coating comprises a polymeric binder and particles of a palladium-doped zeolite with a CHA framework type, wherein the packaging material is a lid for a container. 2. The packaging material according to claim 1 , wherein the packaging material is a bottle lid. 3. The packaging material according to claim 1 , wherein the packaging material is a lid of a clamshell box. 4. A packaging material for the adsorption of volatile organic compounds, wherein the packaging material comprises a coating on its surface, and wherein the coating comprises a polymeric binder and particles of a palladium-doped zeolite with a CHA framework type, wherein the packaging material is a strip. 5. The packaging material according to claim 4 , wherein the packaging material is a strip comprising high-density spunbound polyethylene fibers. 6. The packaging material according to claim 1 , wherein the zeolite comprises 0.2 to 2 wt % palladium based on the total weight of doped zeolite. 7. The packaging material according to claim 1 , wherein the zeolite has a silica to alumina molar ratio (SAR) of less than or equal to 100:1. 8. A packaging structure comprising the packaging material according to claim 1 . 9. The packaging material according to claim 4 , wherein the zeolite comprises 0.2 to 2 wt % palladium based on the total weight of doped zeolite. 10. The packaging material according to claim 4 , wherein the zeolite has a silica to alumina molar ratio (SAR) of less than or equal to 100:1. 11. A packaging structure comprising a packaging material according to claim 4 .
