The invention provides a resin additive master batch which can contain a resin additive having a melting point of not higher than 80°C to a high concentration, with which breakage of a strand does not occur and continuous production can be attained, and with which the surface tackiness of pellets is improved.
The resin additive master batch comprises 80 to 150 parts by weight of (B) resin additive having a melting point of not higher than 80°C, and 0.3 to 5 parts by weight of (C) organic acid metal salt, with respect to 100 parts by weight of (A) polyolefin resin. As the (B) resin additive having a melting point of not higher than 80°C, a UV absorber, a hindered amine compound or a mixture thereof is preferred.
