Abstract (en)
[origin: EP4306440A1] The present disclosure providing a cushion pad (100, 300) includes at least one cushion unit (10, 30) including at least one die-cutting region (10, 320), a length of the die-cutting region (10, 320) increased when the die-cutting region (10, 320) is unfolded; the die-cutting region (10, 320) is unfolded to form a buffer layer that causes a second surface (32) to expand in a thickness direction of the second surface (32) to play a buffering and protective role thereof; the die-cutting region (10, 320) is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag (200, 400) with the cushion pad (100, 300) is of a plane structure after production; when the packaging bag (200, 400) is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion pad (100, 300) is expanded to form the buffer layer (14, 321), to protect the object inside the packaging bag (200, 400). The cushion pad (100, 300) and the packaging bag (200, 400) are of plane structures after being manufactured, which can save transportation costs; the cushion pad (100, 300) can be expanded by placing objects or stretching the cushion pad (100, 300) when in use, the cushion pad (100, 300) can be used as a cushion material for filling or wrapping the object, and the packaging bag (200, 400) is used for receiving the object.
