Surface bonding fastener

A surface bonding fastener, comprising:

• first and second members capable of being fastened with each other, each of the first and second members comprising:
• a base sheet;
• and
• a plurality of fastening units on and integrally molded with the base sheet, the plurality of fastening units arranged at intervals in a longitudinal direction and staggered in a transverse direction perpendicular to the longitudinal direction,
• each of the plurality of fastening units comprising:
• a first hook having a first body extending from the base sheet and a first hook portion extending from the first body and bended toward a first direction;
• and
• a second hook having a second body extending from the base sheet and a second hook portion extending from the second body and bended toward a second direction opposite to the first direction,
• wherein the second body is adjacent to the first body in the transverse direction and integrally formed with the first body,
• wherein the first body and the second body only partly overlap with each other in the longitudinal direction, and an overlapping degree between the first body and the second body in the longitudinal direction is configured to be determined based on a desired fastening strength between the first member and the second member, and
• wherein when the first member and the second member are fastened with each other, the first hook portions of the first member are configured to be engaged with the first hook portions of the second member, and the second hook portions of the first member are configured to be engaged with the second hook portions of the second member.
