Resin composition for skin packaging, film for skin packaging, method for producing film for skin packaging, skin packaging material, and skin packaging body

The resin composition for skin packaging contains an ionically crosslinked polymer (A) of an ethylene-unsaturated carboxylic acid copolymer, and the ionically crosslinked polymer (A) of the ethylene-unsaturated carboxylic acid copolymer satisfies 11 < = (X * Y * 0.01)/Z. The resin composition for skin packaging contains an ionomer (A) of an ethylene-unsaturated carboxylic acid copolymer, and the melt tension of the ionomer (A) of the ethylene-unsaturated carboxylic acid copolymer as measured by a specific measurement method is 320 mN or more. 贴体包装用树脂组合物，其包含乙烯·不饱和羧酸系共聚物的离子交联聚合物(A)，前述乙烯·不饱和羧酸系共聚物的离子交联聚合物(A)满足11≤(X×Y×0.01)/Z。贴体包装用树脂组合物，其包含乙烯·不饱和羧酸系共聚物的离子交联聚合物(A)，由特定的测定方法测得的前述乙烯·不饱和羧酸系共聚物的离子交联聚合物(A)的熔融张力为320mN以上。
