The present invention provides a resin composition comprising a saponified ethylene-vinyl acetate copolymer (A) and a substituted 9,10-anthraquinone (B) having a substituent at at least one of the 2-, 3-, 6- and 7-positions and showing a percent weight loss when stood with heating at 250° C. for 60 minutes of not more than 5% and a multilayer structure including the resin composition as an intermediate layer. This multilayer structure is superior in appearance, oxygen barrier property, further forming stability, resistance to pinholes, adhesion between layers and the like, and is useful for packaging of foods such as meat, ketchup, soybean paste, beer and the like.
本发明提供了一种树脂组合物,该树脂组合物由皂化乙烯-醋酸乙烯共聚物(A)和取代9,10-蒽醌(B)组成,取代基至少位于2-、3-、6-和7-位中的一个,在250℃加热60分钟后重量损失率不超过5%,并提供了一种多层结构,其中包括作为中间层的树脂组合物。这种多层结构在外观、氧气阻隔性、进一步成型稳定性、抗针孔性、层间粘合性等方面都很出色,适用于肉类、番茄酱、豆酱、啤酒等食品的包装。
