Abstract: A separator sheet for disposition between layers of newspaper bundles on a movable pallet, for stabilizing the newspaper bundles as the pallet is moved. The separator sheet has a central portion and an outer portion circumscribing the central portion. The outer portion includes inclined sections extending at acute angles to, and in both directions from, the central portion. The inclined sections engage, and exert pressure against the peripheral edges of the layers of newspaper bundles both above and below the separator sheet for stabilizing the layers of newspaper bundles on the pallet. The separator sheet is preferably a unitary structure, formed of a resilient plastic material.
