There is provided a resin-impregnated decorative paper (2) formed by impregnating a decorative paper (4) with an impregnating resin (5). The decorative paper (4) includes: a base paper (6); a picture pattern layer (7) provided on a surface (6a) side of the base paper (6); a filling layer (8) provided on a surface (7a) of the picture pattern layer (7); and a foamed resin layer (9) provided on a surface (8a) of the filling layer (8). The filling layer (8) contains at least one of an epoxy-based resin, an acrylic-based resin, a urethane-based resin, and a casein-based resin.

A resin foam composition comprises, at least, a resin emulsion and cellulose nanofibers.

A resin foam composition comprises, at least, a resin emulsion and cellulose nanofibers.

Disclosed are polymeric foamed compositions, foam padded materials that include such polymeric foamed compositions disposed on a sheet material, and packaging articles (e.g., envelopes) made from such foam padded materials. The polymeric foamed composition on the sheet material has a plurality of foamed structures formed from the foamable composition attached to the sheet material by a layer of the foamable composition, and the plurality foam structures each having a hollow core and a foam exterior shell.
