The present invention relates a universal vinyl bag for packaging high viscosity liquid and a method for manufacturing the same. According to the present invention, the universal vinyl bag has a unique structure allowing a pumping body of a gun to be coupled to a coupler of a second opening part when liquid is pumped to be discharged by using the gun, which is widely used and has a pumping and injection function, such as a grease gun, thereby allowing the gun to have a universal size and having an airtight structure. Therefore, the universal vinyl bag can be used without pollution caused by the leakage of content when pumping. Moreover, when a manufacturer charges high viscosity liquid into the bag, discharges a large amount of content, and discharges less amount of residual content, a first opening part can be conveniently used. The second opening part has an airtight coupler grade structure fitted to the gun. The first opening part is included to be used in a poor environment through the second opening part, is tied up into a nipple shape to be closed, and is opened to be used if necessary. |
