A multi-panel sterilization assembly that includes a barrier panel formed of a permeable material, barrier panel bolsters at or adjacent at least a portion of two edges of the barrier panel, a fold protection panel, and at least one panel attachment means. The barrier panel has a first end and a second end opposite the first end such that the barrier panel has a length that is the distance from the first end to the second end and a midpoint along the length generally delineating the barrier panel into a content receiving region and a content covering region. The barrier panel bolsters prevent the edges of the barrier panel from folding back onto itself, i.e. back towards the unfolded position, during unfolding of the barrier panel after sterilization.
