Abstract: A wrinkle-reducing insert for suitcases and the like containers within which folded, wrinkleable, cloth-like garments and the like items are packed for travel purposes, comprises a stack of substantially identical, thin, smooth, plastic sheets which are flexible, but generally stiff enough to avoid crumpling or wrinkling. The stack of sheets is held together as a unit by a cord-like or rod-like connector loosely fitted through adjacent aligned holes formed in the sheets so that the sheets may be freely separated apart from each other. The sheets are sized to closely fit within the walls defining the container for limiting transverse movement of the sheets within the container. Folded cloth-like items are packed, layer-by-layer, between adjacent pairs of sheets for substantially filling the container, so that the container may be transported and stored during travel and the packed items will substantially resist wrinkling while packed in the container.
