POLYAMIDE RESIN COMPOSITE PELLET, PELLET AGGREGATE, RESIN FILM, AND MULTILAYER FILM

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin composite pellet and a pellet aggregate that can form a film in which the mixing of foreign matters such as dust or the like is suppressed and the generation of a gel-like material is suppressed without using an expensive equipment and are excellent in extrusion processability, to provide a resin film produced by melting and mixing the pellet aggregate and molding the same, and to provide a multilayer film having at least one layer of the resin film.SOLUTION: The polyamide composite pellet is composed of (X) a polyamide containing a diamine unit containing 70 mol% or more of a meta-xylylenediamine unit and a dicarboxylic acid unit containing a 70 mol% or more of an α, ω-linear aliphatic dicarboxylic acid unit, (A) one or more kinds of components selected from the group consisting of a surfactant, a polyether, a quaternary ammonium salt and a sulfonate, and (B) one or more kinds of components selected from the group consisting of an alkali metal salt and an alkaline earth metal salt. The polyamide resin composite pellet is produced by contacting at least a part of the component (A) on the surface of the pellet substrate produced by molding a resin composition including the polyamide (X).
