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 antistat 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 non-porous to minimize bleed-through of melted foam.
