A modified atmosphere package includes first and second compartments separated by a partition member that is substantially permeable to oxygen. The first compartment contains an oxygen scavenger activated with an oxygen scavenger accelerator. The second compartment contains a retail cut of raw meat. Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member, while other techniques directly absorb oxygen within the second compartment by locating a second oxygen scavenger within the second compartment.

Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member to a level inhibiting the formation of metmyoglobin in the raw meat.

A carton for a bag stack comprises a bottom wall, opposing front and back walls, and opposing first and second side walls bridging the opposing front and back walls. The first side wall forms a first pair of detents in proximity to the respective front and back walls. The second side wall forms a second pair of detents in proximity to the respective front and back walls. The front and back walls each include a profiled upper edge forming a window adapted to accommodate a human hand and allow retrieval of the plastic bags within the carton via the window. The bag stack includes first sets of plastic bags and second sets of plastic bags interleaved (alternately-arranged) with each other. Each set of plastic bags may include one or more plastic bags. The first and second sets of plastic bags are oriented in opposite longitudinal directions. The thickened portions of the first sets of bags are adjacent to and extend across the width of the front wall, while the thickened portions of the second sets of bags are adjacent to and extend across the width of the back wall. The distance between the first and second side walls is such that the first and second pairs of detents inhibit inward sliding of the interleaved sets of plastic bags, thereby maintaining the orderliness of the stack.
