Foldable air cushioned structure

A foldable air cushioned structure formed by two outer films, comprising:

• a plurality of heat-sealing lines formed by linear heat-sealing the two outer films for attaching parts of the two outer films, wherein the heat-sealing lines are arranged with substantially the same interval;
• a plurality of air cylinders positioned between the heat-sealing lines;
• a plurality of nodes disposed inside the air cylinders by heat-sealing for attaching parts of the inner surfaces of the two outer films, wherein the nodes are arranged in lines perpendicular to the heat-sealed lines to form a plurality of foldable lines;
• and
• a plurality of clasp points formed on the outer surface of the two outer films by heat-sealing for attaching parts of the outer surfaces of the two outer films,
• wherein after folded along the foldable lines, each of the air cylinders forms:
• two side portions forming a receiving space therebetween;
• at least one supporting portion formed in the receiving space and the supporting portion comprising a propping section and two connecting sections positioned at two sides of the propping section after the air cylinders are folded via the nodes, wherein at least one of the clasp points is positioned corresponding to two adjacent connecting sections to attach the two adjacent connecting sections, and at least two of the clasp points are positioned corresponding to one of the connecting sections and the adjacent side portion to attach the connecting sections and the adjacent side portion;
• and
• at least two bottom portions connecting to at least one of the connecting sections and the side portions, wherein each of the bottom portions is formed a support bottom surface between each of the side portions and the adjacent connecting section or between two adjacent connecting sections.
