Wound packing material comprising a resilient polymer-based foam sheet of a predetermined thickness. The foam sheet includes at least one slit of a predetermined length that extends from the foam surface into the foam to a predetermined depth. This slit, or slits, permits the foam, when folded upon itself, to occupy a smaller volume than the foam would occupy when folded over upon itself in the same manner, but in the absence of the slit.
