Title:
BUFFER PAD AND PACKAGING BAG
Document Type and Number:
WIPO Patent Application WO/2023/142461
Kind Code:
A1
Abstract:
A buffer pad (100, 300). The buffer pad comprising at least one pad unit (10, 30). The pad unit (10, 30) comprising at least one die cutting region (12, 320). When the die cutting region (12, 320) is unfolded, the length increases. The die cutting region (12, 320) unfolds to form a buffer layer. The buffer layer enables the second surface (32) to expand in the thickness direction, so as to have a buffering and protecting effect. After the die-cutting region (12, 320) is unfolded, a three-dimensional grid structure is formed. Further disclosed is a packaging bag (200, 400) manufactured with the pad units. The packaging bag (200, 400) is of a planar structure after being manufactured. When the packaging bag (200, 400) is used after transportation, the buffer pad(100, 300) is expanded to form a buffer layer (14, 321) by means of placing an object thereon or being under a pushing force, so that the loaded object is protected, and the transportation cost can be saved. When in use, the buffer pad (100, 300) can be expanded by placing an object thereon or stretching, the buffer pad (100, 300) can be used as a buffering material to fill or wrap an object, and the packaging bag is used for holding an object.
