摘要： PROBLEM TO BE SOLVED: To provide an easily openable multi-layer package which a wide heat-seal processing temperature range, and a simple structure, which is strong against shocking external forces, and also, is stable in strength, and satisfies both of sealability and easy openability. SOLUTION: This easily openable multi-layer package 1 includes a container body 10, and a lid member 20 having an opening tab. In this case, the container body is formed by molding a multi-layer sheet of five layers or more, and on the opening section peripheral edge of which a flange section 14 is formed. The lid member having the opening tab is heat-sealed to the flange section, and closes the opening section 13. The innermost layer of the container body, which is the heat-sealing section 16 of the flange section is peeled together with the lid member when opening. The easily openable multi-layer package 1 is heat-sealed by a first sealing section 16A which is formed in a manner to surround the opening section, and a second sealing section 16B which is formed in a manner to surround the opening section along the first sealing section in the region of the first sealing section, and has a narrower width than the first sealing section. At a position according to the opening tab of the lid member, the second sealing section projects to the outer peripheral side of the flange section, and the second sealing section is discontinuous for the easily openable multi-layer package.
