Summary: | The utility model relates to a buffering packaging bag. A two-layer bag body is composed of an inside wall and an outside wall and processed through a static electricity removing way in advance. A hermetic cabin is arranged between the inside wall and the outside wall. The center of the inside wall which is positioned at the inner layer is surrounded into containing space with an opening for containing articles, and a corner of the packaging bag is provided with a choke valve. The choke valve is filled into the hermetic cabin to cause the buffering packaging bag to intumesce and force the air in the containing space to discharge from the opening, and the inside wall is tightly coated and contacted on the articles. The air which is filled in the hermetic cabin forms a favorable buffering coating effect to the articles. |
