  • Patent number: 9332782
    Abstract: The invention relates to an article for oxygen absorption that is a container containing a water-soluble on source, a water activated oxygen scavenger, and a rupturable canister of hydrated polymer. The hydrated polymer comprises a superabsorbent polymer. The water-soluble on source comprises a salt. The invention in another embodiment relates to a method for providing timed oxygen absorption using the article as above with rupturing of the canister to release the water carrying superabsorbent such that it will contact the oxygen scavenger and on source thereby leading to activating the oxygen scavenger.

  • Patent number: 8927078
    Abstract: The present invention relates to encapsulated activated carbon and a method of preparing the same to protect the structure of the activated carbon and preserve the odor absorbing capability of the activated carbon particles. Particularly, the present invention is directed to a polymer article having odor absorption capabilities comprising a film comprising a matrix polymer and activated carbon particles at least partially encapsulated with a non-water soluble amorphous polymer, wherein the non-water soluble amorphous polymer is incompatible with the matrix polymer. The polymer article can be a bag.

  • Publication number: 20130102695
    Abstract: Single and multilayer porous polyolefin films are prepared by extruding polyolefin with poly(lactic acid) (PLA) and followed by uniaxial or biaxial stretching. PLA is used as a pore former that creates porosity. The film provides adjustable gas and water vapor transmission rate by varying the PLA content. Sorbents may optionally be added in the formulation in selective layers. The porous films are useful in packaging and consumable applications. In particular, partially miscible blends of PP and PLA is useful for creating fine porosity due to the fine PLA domains in the miscible blends.
