Gas-sealed body with cushioning function

A gas-sealed body with cushioning function, the gas-sealed body being adapted to be inflated by a processing machine, wherein

• the processing machine comprises an inflation bar and a plurality of pressing wheels adjacent to the inflation bar,
• the inflation bar is adapted to inflate the gas-sealed body, and
• the pressing wheels are adapted to roll on a rolling track of the gas-sealed body for conveying the gas-sealed body,
• the gas-sealed body comprising:
• two outer films and two inner films, wherein
• the inner films are between the outer films, and
• a length of each of the inner films is shorter than a length of each of the outer films;
• an inflation channel formed between a first transversal heat-seal line and a second transversal heat-seal line of the gas-sealed body, wherein
• the first transversal heat-seal line and the second transversal heat-seal line are not intersected with each other,
• the inflation channel comprises an inflation port, and
• the inflation bar is adapted to be put in the inflation port;
• a plurality of gas inlets formed between the two inner films, wherein
• one of opposite surfaces of the two inner films has a heat-resistant area;
• after a heat-resistant material is coated on the heat-resistant area, the gas inlets are formed when the second transversal heat-seal line is formed by heat sealing;
• wherein
• the gas inlets are at positions between the inner films and the positions correspond to the heat-resistant material, and
• the two inner films are not adhered with each other at positions having the gas inlets;
• a plurality of pillow structures formed by heat sealing and spaced apart from each other, wherein
• each of the gas inlets is located between two adjacent pillow structures,
• each of the pillow structures comprises an upper pillow portion and a lower pillow portion connected to the upper pillow portion,
• the upper pillow portion is located in the heat-resistant area,
• the lower pillow portion is located out of the heat-resistant area,
• each of the outer films adheres with the inner films at the lower pillow portion,
• a bottom portion of the lower pillow portion is connected to a rolling line of the gas-sealed body, and
• the rolling line is aligned transversally,
• a width range of the rolling track encompasses the rolling line and at least a portion of the inflation channel, and
• the pillow structures are adapted to be pressed by and positioned with the pressing wheels stably to allow a pressure from the pressing wheels to be distributed over the gas-sealed body when the pressing wheels roll on the pillow structures;
• and
• a plurality of gas chambers formed by intersecting a plurality of longitudinal heat-seal lines with the second transversal heat-seal line, wherein
• the longitudinal heat-seal lines are spaced apart from each other;
• each of the gas chambers comprises at least one of the gas inlets, at least one cushion-part gas column, and a main-part gas column, wherein
• the at least one cushion-part gas column is located and defined between adjacent two of the pillow structures, and extends from the corresponding gas inlet toward the rolling line,
• the main-part gas column communicates with the at least one cushion-part gas column at the rolling line,
• when the inflation bar inflates each of the inflation inlets, the at least one cushion-part gas column and the main-part gas column are inflated and expanded in order, and
• the at least one cushion-part gas column provides a holding force for the pressing wheels when the pressing wheels roll on the gas-sealed body.
