Abstract:
The invention provides a biodegradable oxygen absorbing plastic comprising a biodegradable substrate a sufficient concentration of reduced iron particles to adsorb oxygen in significant quantities and reduce the deformation temperature of the substrate substantially below the deformation temperature without iron particles present.
Abstract:
A material handling apparatus for conveying an article having a ferromagnetic component includes a hopper, a discharge, and a magnet. The hopper has an inlet and outlet and defines a hopper volume for receiving a plurality of the articles to be conveyed. The discharge is spaced from and downstream of the hopper. The magnet is movable between an attracting position proximate the hopper and a discharge position proximate the discharge.
Abstract:
The invention provides for an extended shelf life single portion package including a container having therein a material for mammal ingestion that degrades by exposure to oxygen, water vapor, or carbon dioxide, an absorber selected from at least one of a carbon dioxide absorber, water vapor absorber, and oxygen scavenger wherein the container is substantially impervious to oxygen, carbon dioxide, and water vapor.
Abstract:
A sulfur dioxide reducing composition for reducing the headspace concentration of sulfur dioxide in fruit packages includes a sulfur dioxide absorber having pores sized to retain sulfur dioxide therein and a clinching absorber on the sulfur dioxide absorber with which the sulfur dioxide reacts irreversibly with the sulfur dioxide.
Abstract:
Multilayer oxygen absorbing structure comprising at least two reactive oxygen scavenging layers arranged in sequence: a rapidly absorbing highly reactive oxygen-scavenging system, comprising an oxygen permeable matrix polymer and an oxygen scavenger, and a long life layer comprising high passive oxygen barrier matrix polymer, and an oxygen scavenger.
Abstract:
The invention general provides a method of absorbing gases from manufactured articles comprising providing a gas absorbent in gaseous contact with the manufactured article wherein the gas absorber comprises activated carbon, molecular sieve, and alkaline salt.
Abstract:
The invention provides for an extended shelf life package comprising a material for human ingestion that degrades by oxidation, comprising an oxygen scavenger comprising a transition metal oxygen scavenger, a container substantially impervious to oxygen, wherein the container has a filter suspended in the container, the filter holds the material for human ingestion, and the container also holds the oxygen scavenger. In another embodiment, the invention provides for an extended shelf life package comprising human ingestible material that degrades by giving off CO 2 comprising a carbon dioxide scavenger, a container substantially impervious to carbon dioxide, wherein the container has a filter suspended in the container, the filter holds the human ingestible material, and the container also holds the carbon dioxide scavenger.
Abstract:
The invention relates to an oxygen scavenging material comprising an oxygen scavenger disbursed in a low density foam, wherein the oxygen scavenger has a particle size of less than 25 µm. In another embodiment the invention relates to a product package comprising a foam tray, product in the tray, and a polymer cover surrounding the meat and tray, wherein the foam tray comprises an oxygen scavenging material, wherein the oxygen scavenging material comprises an oxygen scavenger disbursed in the foam and wherein the oxygen scavenger has a particle size of less than 25 µm.
