Abstract: An air-evacuable storage bag with multiple air exit holes includes two sheets of outer film, two sheets of inner film, a crosswise hot sealing line formed by hot-sealing the two sheets of outer film and the two sheets of inner film, a storage space used for accepting an article, and an air exhaust area; the two sheets of outer film includes a first end and a middle end; the two sheets of inner film are placed in between the two sheets of outer film; the storage space is formed between the crosswise hot sealing line and the first end; the air exhaust area is formed between the crosswise hot sealing line and a top end of the two sheets of outer film; a plurality of air outlets are formed intermittently between the two sheets of inner film at the crosswise hot sealing line; the air outlets can be opened automatically.

Abstract: A multi-sectional clamping type air enclosure is constituted by connecting a second, a third, and a fourth air cylinder sheet(s) sequentially in series to a first air cylinder sheet, in which an air filling passageway is disposed in the first air cylinder sheet to allow air to be filled in a plurality of first air cylinders and the second air cylinder sheet(s), the third air cylinder sheet and the fourth air cylinder sheet(s) communicated therewith to be filled with air and expanded. Thereafter, the second air cylinder(s) and the fourth air cylinder sheet(s) are bended toward the third air cylinder sheet to form approximately a U-typed body, and auxiliary air cylinders of the air cylinder sheet are then bended toward main air cylinders of the air cylinder sheet to cause side air cylinders of the air cylinder sheet to be approximately perpendicular to the main air cylinders.

Abstract: A method for making a cushioning air bag with a predetermined opening in an air cylinder turning zone, including: providing an air cylinder sheet; adhering the two sheets of outer film to form turning points; determining a turning middle line on the air cylinder sheet; configuring nodes on two respective sides of the turning middle line; turning the air cylinder sheet along the turning middle line; and adhering two sides of the turned air cylinder sheet with lateral heat sealing lines; wherein two lateral sides of the air cylinder sheet between nodes and the turning middle line form a non-heat sealing section; a bottom surface is formed between turning points, the non-heat sealing section of the turning zone is expanded to form a lateral polygonal opening, and a supporting surface is formed on a bottom of the opening, after the air cylinder sheet is filled with air.

Abstract: An apparatus and method for manufacturing a double layer air cylinder type air enclosure uses a middle film conveying unit to provide a middle film, a plurality of inner film conveying units to provide a plurality of inner films to stack on two sides of the middle film, a first hot sealing apparatus to hot-seal the plurality of inner films and the middle film to allow two sides of the middle film to be respectively formed with a check valve with an air passageway, an outer film conveying unit to provide two sheets of outer film to respectively stack on the outside of the check valve and a second hot sealing apparatus to hot-seal the plurality of outer films and the middle film to allow an air storable air chamber to be formed between the middle film and the each sheet of outer film.
