Abstract
The present invention relates to a laminate including a protection layer, a barrier layer, and a heat sealing layer, in which a product of a tensile elastic modulus A in a 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 tensile elastic modulus B to the tensile elastic modulus A, a value of the tensile elastic modulus C to the tensile elastic modulus A, and a value of the tensile elastic modulus C to the tensile elastic modulus B are each 0.1 to 10.
Claims7
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 optional direction orthogonal 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 tensile elastic modulus B to the tensile elastic modulus A, a value of the tensile elastic modulus C to the tensile elastic modulus A, and a value of the tensile elastic modulus C to the tensile elastic modulus B are each 0.1 to 10.
