Resin composition for sealant, laminate, packaging material, and package

A resin composition for a sealant, comprising:

• a resin (A) that is an ethylene-(meth)acrylic acid ester copolymer in which a content of a (meth)acrylic acid ester unit is from 10% by mass to 25% by mass;
• a tackifying resin (B) having a ring and ball method softening point of from 100° C. to 130° C.;
• a resin (C) that is an ethylene-vinyl ester copolymer in which a content of a vinyl ester unit with respect to a total amount of the ethylene-vinyl ester copolymer is from 7% by mass to 13% by mass;
• a resin (D) that is at least one selected from the group consisting of an ethylene-α-olefin copolymer elastomer and a styrene-based elastomer;
• and
• an erucic acid amide,
• wherein a density of the ethylene-α-olefin copolymer elastomer is from 850 kg/m3 to less than 900 kg/m3,
• a content of the resin (A) is more than 45% by mass with respect to a total amount of resin components in the resin composition for a sealant,
• a content of the tackifying resin (B) is from 0.1% by mass to 3% by mass with respect to a total amount of resin components in the resin composition for a sealant,
• a content of the erucic acid amide is from 0.01% by mass to 0.096% by mass with respect to a total amount of resin components in the resin composition for a sealant,
• a total content of resin components is 80% by mass or more with respect to a total amount of the resin composition for a sealant, and
• an elution amount of the resin composition for a sealant into normal heptane is 30 μg/mL or less.
