An airbag with a bent head portion and a repeated sealing and filling effect comprises a bag body formed of buffer air columns, and heat-sealing nodes formed on the air column, such that the air column is bent when passing the node. A containing groove is formed in the bag body, and the bag body includes a bag mouth interconnected to the containing groove; a plurality of inflatable extended-section air columns arranged on a side of the external periphery of the bag mouth, and a non-inflatable protruding plate is arranged at an edge of the extended-section air column; an extended-section plate, disposed on the other side of the bag mouth, and a disposing entrance is formed between the extended-section plate and the protruding plate for a repeated use of the airbag. The airbag and its manufacturing method overcome the problem of the conventional packaging bag that cannot be used repeatedly. |
