ABSTRACT Cushioned packaging and protecting with laminate of a thin resilient resin foam layer adhered to a strong supporting sheet. Laminate may also have metal foil or metallized layer, and/or water-repellent surface layer, and/or anti-stat surface layer and/or volatile corrosion inhibitor and/or a cohesive-nonadhesive surface coating or a low-tack pressure-sensitive adhesive coating. Automatic packaging of a series of articles between long webs of wide cushioning laminates having faces of heat-sealable foam. One web is fed foam-face-up across a table, the articles to be packaged placed on it in spaced locations, heat applied to foam edges to just about melt the foam there, and a second web applied foam face-down over the spaced articles and heat-sealed to the lower web at its edges. Transverse heat sealing, and severings, are effected between successive articles. The heat-sealings can be set by cold pressings. Web backings can be made relatively nonporous to minimize bleed-through of melted foam.
