Packaging material, blank sheet, and packaging method

Abstract

A packaging material comprising a body, a lid provided to be openable and closable on the main body and a lock tab provided on the body. The lid has a first main surface and a second main surface opposite to the first main surface. The lid is provided with a through-hole penetrating in a first direction from the first main surface toward the second main surface. The lock tab has an outer shape at least partially larger than the through-hole. In a state where the lid is closed with respect to the body and the lock tab is disposed on the first main surface side, when the lock tab moves in the first direction, at least one of the lock tab or the through-hole is deformed, the lock tab is inserted into the through-hole, and the lock tab is disposed on the second main surface side.
