Abstract
The present disclosure provides a resin composition which contains: (A) a saponified ethylene-vinyl ester copolymer; and (B) a cinnamate; wherein the cinnamate (B) is present in a proportion of 0.01 to 10 ppm based on the amount of the saponified ethylene-vinyl ester copolymer (A). Therefore, the use of the resin composition makes it possible to produce a film which is highly transparent, capable of absorbing ultraviolet radiation of a specific wavelength range (e.g., UV-B and UV-C having a wavelength shorter than 320 nm) and free from an odor problem and the like.
