A resin-additive masterbatch is provided in which a low-melting resin additive can be contained in a high concentration and which can be continuously produced without suffering strand breakage. The surface of the masterbatch has reduced tackiness. The resin-additive masterbatch is characterized by comprising 100-900 parts by mass of a resin additive (B), 0.1-10 parts by mass of a metal salt (C) of an organic acid which is not a fatty acid, and 0.1-10 parts by mass of a gellant (D) relative to 100 parts by mass of a crystalline resin (A), wherein the resin additive (B) is a resin additive which, when melted by heating to 250 DEG C, subsequently cooled to 80 DEG C, and then held for 30 minutes, remains liquid. |
