    Abstract: A method for forming a protective film on a foam cushion including steps of preparing the cushion, applying a hot-melt adhesive, hot pressing a resin film, and cutting. Therein, the cushion is applied with a hot-melt adhesive layer, and a heated metal roller is used to press the resin film onto the hot-melt adhesive layer. The melting point of the resin film is greater than that of the hot-melt adhesive layer, and the heating temperature of the metal roller is between the melting point of the resin film and the melting point of the hot-melt adhesive layer, so that while the resin film is pressed on the hot-melt adhesive layer by the metal roller, the resin film is stuck by the hot-melt adhesive layer, thereby forming a protective film on the outer surface. The method features quick resin film and reliable film affixation.

    Abstract: A foam pad structure having a protective film includes a substrate layer, a hot glue layer, a printed pattern layer, and an adhesive film. The substrate layer is made of a foam material. The substrate layer has two surfaces arranged oppositely on its upper and lower sides. The hot glue layer is coated on at least one of the two surfaces of the substrate layer. The hot glue layer has an adhesive surface facing away from the substrate layer. The printed pattern layer is composed of a pigment containing the same composition as the hot glue layer. The printed pattern layer is printed on the adhesive surface of the hot glue layer. The hot glue layer and the printed pattern layer are melted between the substrate layer and the adhesive film.

    Abstract: A method for patterning a foam pad includes transversely cutting the foam pad so that the foam pad has a cut surface; covering the cut surface with a dye paper on which a predetermined pattern is formed using a dye, performing a first hot press process on the dye paper so that the dye on the dye paper is vaporized and transferred to the cut surface, and removing the dye paper; applying a transparent PU resin onto the cut surface that has been dyed, and curing the PU resin; and performing a second hot press process on the PU resin on the cut surface, so that the cut surface is increased in density and the PU resin encloses the dye, thereby making the dye firmly attached to the cut surface.
