摘要:
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.
摘要:
An oxygen absorbing composition having an effective amount of at least one oxygen absorbent contained in an emulsion. An oxygen absorbing product is produced by dispersing an oxygen absorbent in an emulsion to form an oxygen absorbing composition and transferring the oxygen absorbing composition onto a substrate.
摘要:
A device for controlling relative humidity in an environment with a solidified humectant composition. The solidified humectant composition is made from a humectant salt, water, and a carrier. The solidified humectant may be formed into a tablet with the aid of a binder, or it may be contained within a thermoformed felt material, a sachet, or a water permeable canister. In a preferred embodiment, the sachet is made of a micro-perforated polyester/paper/polyethylene material. Preferred humectant salts include CaCl2, K2CO3, LiCl, NaCl, K2SO4, and combinations thereof. A preferred embodiment of the present invention includes the use of one or more of: an antimicrobial agent, activated carbon, a volatile organic, a moisture adsorber and an oxygen absorber, in combination with the solidified humectant salt.

摘要:
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.
摘要:
A water vapor adsorption and water retaining composition containing particulate calcium chloride and particulate vermiculite in a flexible container having a side of spun-bonded polyethylene heat sealed to a side of extrusion coated polyethylene on polyester. The foregoing composition can also contain clay.
摘要:
An oxygen-absorbing label and a moisture-sensitive label. The oxygen-absorbing label consists of a base sheet, adhesive on the base sheet for securing the base sheet to an internal surface of a container, an oxygen-absorbing composition on the base sheet, and a permeable cover sheet secured to the base sheet to confine the oxygen-absorbing composition therebetween. The moisture-sensitive label is one wherein a moisture-sensitive material is used as part of the label instead of the oxygen-absorbing composition. The moisture-sensitive material may be a moisture adsorber such as silica gel or molecular sieve, or it may be a moisture supplier such as hydrogel. A plurality of the foregoing labels are mounted on a web to be used with conventional labeling equipment.
摘要:
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.
摘要:
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.
