Zusammenfassung:	Provided are a resin composition and the like which contain an ethylene-vinyl alcohol copolymer (EVOH) and which are suppressed in necking and die build-up during melt molding. A resin composition which contains EVOH (A) and crotonaldehyde (B1), and further contains at least one substance selected from the group consisting of 2, 4-hexadienal (B2) and 2, 4, 6-octatrienal (B3), and which satisfies formulae (1) and (2). In formulae (1) and (2), b1 is the content (ppm) of crotonaldehyde (B1) with respect to EVOH (A), b2 is the content (ppm) of 2, 4-hexadienal (B2) with respect to EVOH (A), and b3 is the content (ppm) of 2, 4, 6-octatrienal (B3) with respect to EVOH (A). 2.0 < = b1/(b2 + b3) lt; 150.0... (1). (2) b2 + 2b3 < = 0.65. 提供包含乙烯-乙烯醇共聚物(EVOH)且熔融成型时的缩颈和口模积料受到抑制的树脂组合物等。树脂组合物，其包含EVOH(A)和巴豆醛(B1)，还包含选自2,4-己二烯醛(B2)和2,4,6-辛三烯醛(B3)中的至少1种，所述树脂组合物满足下述式(1)和(2)。式(1)和(2)中，b1为巴豆醛(B1)相对于EVOH(A)的含量(ppm)，b2为2,4-己二烯醛(B2)相对于EVOH(A)的含量(ppm)，b3为2,4,6-辛三烯醛(B3)相对于EVOH(A)的含量(ppm)。2.0≤b1/(b2+b3)
