An oxygen scavenging polyolefin composition and methods of making thereof are described herein. In one approach, the composition includes a continuous non-polar polyolefin matrix having oxygen scavenging domains dispersed therein. The oxygen scavenging domains include an oxidizable polymer, a transition metal catalyst or salt thereof, and a catalytic promoter effective to bind with oxygen passing through the continuous non-polar polyolefin matrix. The oxygen scavenging domains forming a discrete polar region within the continuous non-polar polyolefin matrix. The composition further includes a polymeric compatibilizer having a polar moiety and a non-polar moiety and in amounts effective to uniformly disperse the polar oxygen scavenging domains in the continuous non-polar polyolefin matrix.

Two compartment container

A food product container includes a molded tray having at least one cell for holding a food product. A removable cover, such as lidding film, seals the cell in preparation for shipment. A utensil, such as a spoon or knife or the like, is integrally molded with the container.

Polypropylene ultra-lightweight food containers are provided which have good impact resistance at low temperatures. Such polypropylene ultra-lightweight containers can be used for packaging refrigerated or frozen food products. The use of polypropylene to prepare such containers allows for significant reduction in the thickness of container components without significant reduction in impact strength. The polypropylene ultra-lightweight containers of the present invention are prepared by injection molding. The polypropylene useful in preparing the food containers of this invention contains about 15 to about 25 molar percent polyethylene and has a melt flow index of about 30 to about 50 g/10 min. Weight reductions of about 20 to 40 percent can be obtained without significantly reducing impact resistance as compared to conventional polyethylene containers.
