Product

A product comprising:

• a package comprising a multilayer structure;
• and
• a content contained in the package, the content having a sodium chloride content of 1% by mass or more,
• wherein
• the multilayer structure comprises:
• a barrier layer (A) comprising an ethylene-vinyl alcohol copolymer (a) as a main component;
• an inorganic vapor-deposited layer (B) laminated on the barrier layer (A), the inorganic vapor-deposited layer (B) having an average thickness of 7 nm or more and 100 nm or less;
• and
• a heat-sealing layer (E) which is an outermost layer on a side opposite to 1 a side of the barrier layer (A) on which the inorganic vapor-deposited layer (B) is laminated, the heat-sealing layer (E) comprising a polyolefin (e) as a main component,
• wherein
• a total average thickness of layers comprising a polyolefin resin as a main component and being laminated on a side opposite to a side of the barrier layer (A) on which the inorganic vapor-deposited layer (B) is laminated is 45 μm or more, and
• the heat-sealing layer (E) is positioned on an inner surface side of the package.
