1. A laminate comprising:
a protection layer;
a barrier layer; and
a heat sealing layer,
wherein the barrier layer has a polyamide-based resin layer and an ethylene-vinyl alcohol-based copolymer layer,
the heat sealing layer contains a polypropylene as a main component,
when an orthogonal direction to a thickness direction of the laminate is used as a reference direction, a product of a tensile elastic modulus A in the reference direction, a tensile elastic modulus B in a direction forming an angle of 45° with respect to the reference direction, and a tensile elastic modulus C in a direction forming an angle of 90° with respect to the reference direction is 0.22 (GPa)3 or less, and
a value of the ratio of the tensile elastic modulus B to the tensile elastic modulus A, a value of the ratio of the tensile elastic modulus C to the tensile elastic modulus A, and a value of the ratio of the tensile elastic modulus C to the tensile elastic modulus B are each 0.1 to 10,
wherein the polyamide-based resin layer contains nylon 6.
