摘要

A resin composition is provided which, even when the film forming temperature is set high, can suppress excessive increases in torque while suppressing neck-in during film production, which can form, continuously over a long period of time, molded bodies with excellent appearance in which defects such as fish eye and streaks are suppressed, and which can produce, continuously over a long period of time, multilayer structures which can be thermoformed into thermoformed bodies with excellent appearance; a production method of said resin composition, and a molded body and a multilayer structure containing said resin composition are also provided. This resin composition contains (A) an ethylene-vinyl alcohol copolymer with an ethylene unit content of 20-60 mol%, and a boron compound (B), wherein the boron compound (B) contains free boric acid (C), and, in terms of orthoboric acid, the content of the boron compound (B) relative to the ethylene-vinyl alcohol copolymer (A) is 100-5000 ppm, and the ratio of free boric acid (C) in the boron compound (B) in terms of orthoboric acid is 0.1-10 mass%.
