Abstract
A case-ready package and method of reducing discoloration in meat or poultry products enclosed within such packages when the packages are disposed in a stack of two or more packages. A non-textured and substantially smooth gas-permeable substrate is attached to the lower surface of the packages to allow air to flow into an underlying package in a stack of packages, thereby preventing or minimizing premature discoloration of packaged fresh meat or poultry product due to insufficient oxygen flow into such packages when disposed in a stack. In addition, the substrate may contain printed product indicia either directly or in the form of a label attached thereto.
