Abstract: A resin composition according to an aspect of the present invention comprises: an ethylene-vinyl alcohol copolymer (A); and a block copolymer (B) having a block (b1) that includes a vinyl aromatic monomer unit, and a block (b2) that includes an isobutylene unit, wherein the ethylene-vinyl alcohol copolymer (A) and the block copolymer (B) form a co-continuous phase structure; and a DSC curve obtained following heating the resin composition up to a melting point and cooling at a rate of 50° C./min in a differential scanning calorimetry analysis shows two peaks, with a higher peak top temperature falling within a range of 130° C. or greater and 170° C. or less, and a lower peak top temperature falling within a range of 100° C. or greater and less than 130° C. A resin composition may thus be obtained that is able to give a molded article that is superior in balance between gas barrier properties and flexibility.

Abstract: A composite structure disclosed includes a base (X) and a layer (Y). The layer (Y) includes a mixture of a metal oxide (A), a phosphorus compound (B), and a compound (La) (silicon compound). Examples of the phosphorus compound (B) and the compound (La) include a compound containing a site capable of reacting with the metal oxide (A). When the number of moles of metal atoms (M) derived from the metal oxide (A) is denoted by NM and the number of moles of Si atoms derived from the compound (La) is denoted by NSi, 0.01≦NSi/NM≦0.30 is satisfied. When the number of moles of phosphorus atoms derived from the phosphorus compound (B) is denoted by NP, 0.8≦NM/NP≦4.5 is satisfied.
