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. Tranverse 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.

Abstract: Heat sealing of foam-paper laminates and the like around articles to cushion them. Foam can be coated with anti-stat and/or corrosion inhibitor to protect articles against static electricity and/or corrosion. Such coatings can reduce the heat sealing temperature. Laminate portions to be heat sealed can be pre-heated to shorten heat sealing dwell.

Abstract: Surface such as an airplane fuselage or wing, boat deck, floor or vehicle hood or fender, is protected by a thin foam laminate having a nonabrasive foam face laminated to a sheet of paper or other stiffening support and carrying a stratum of adhesive that adheres to, or reduces the tendency of the laminate to slide, when applied over that surface. Protective laminate can also contain volatile corrosion inhibitor (VCI) which can be incorporated in a cohesive-nonadhesive coating or in a pressure-sensitive adhesive coating. A water-repellent layer can also be applied to the outer surface of the foam laminate. A protective laminate with cohesive-nonadhesive coating can also be made anti-static, and any of the laminates can be strengthened with or made of fibers that make them very difficult to tear.

Abstract: A padded packaging sheet for guarding against rust and corrosion, incorporates a coating of volatile corrosion inhibitor (VCI) on a pliable layer of a sealed cell micro-porous foam. The VCI can be incorporated in a cohesive non-adhesive coating on the micro-porous layer or directly on the micro-porous layer in the absence of such cohesive coating. The effectiveness of the VCI can be further enhanced by incorporating in the padded sheet a vapor barrier such as for example, aluminum foil or a film of hydrophobic polymer such as a silicone or a polyester such as Mylar (polyethylene terephthalate). A water-repellent layer can also be added. The sheet can be made anti-static and/or opaque, and strengthened with fibers that make it almost impossible to tear.

Abstract: A padded sheet material for packaging a moisture-sensitive material has a layer of paper which is adhered on one side of a layer of a sealed cell microporous foam polymer, such as microfoam. It is coated on the other side with a layer of a polymer, which excludes the passage of drops of water, but transmits moisture vapor through it whereby any condensate within the package evaporates out through the material. The paper may be reinforced with strands of fiberglass to strengthen it.

Abstract: A padded wrapping and packaging material is comprised of laminated layers of kraft paper and a sheet of closed cellular microfoam, either reinforced by an intermediate fiberglass insert or with the face of the microfoam coated with a cohesive material, or both features may be utilized with the laminate.
