PROBLEM TO BE SOLVED: To provide a multilayer sheet whose surface layer can be delaminated.SOLUTION: Since a second substrate layer of the multilayer sheet contains at least one adhesive, bonding strength between the second substrate layer and a first substrate layer can be increased. The adhesive is at least one selected from the group consisting of a urethane-based elastomer, a styrene-based elastomer, a maleic anhydride-modified polyethylene, a maleic anhydride-modified polypropylene, and an ethylene-vinyl acetate (EVA). In the case of using the multilayer sheet for a container body 2 of an easily unsealable container 1, the first substrate layer and a surface layer can be appropriately delaminated when unsealing a lid 3, thereby allowing the easily unsealable container 1 to be easily unsealed. Furthermore, high sealability can be obtained without requiring a decrease in bonding strength between the surface layer and the first substrate layer. |
