Liquid transport system and a liner bag and a method of using the same

A liquid transport system comprising an intermediate bulk container and a liner bag, wherein the intermediate bulk container comprises a base and a side wall mounted to the base, the base is provided with a valve port, and the liner bag comprises a liner bag body and a discharge port, characterized in that:

• the liner bag body is formed by hermetically welding a front panel and a rear panel along the periphery thereof, the discharge port is hermetically connected to the liner bag body, and a minimum distance between an edge of the discharge port and an weld line of the liner bag body is L, wherein 0≤L≤20 cm, or 0≤L≤0.1*D, where D is the minimum of lengths and widths of the front and rear panels;
• the liner bag is disposed in the intermediate bulk container and the discharge port of the liner bag is installed in the valve port;
• and
• the liner bag is arranged in such a manner that after the liner bag is filled, a plane where the weld line is located is perpendicular to the base.

A method for using a liner bag, characterized in that:

• providing a liner bag comprising a liner bag body, which is formed by hermetically welding a front panel and a rear panel along the periphery thereof;
• and a discharge port, which is hermetically connected to the liner bag body, and the minimum distance between an edge of the discharge port and a weld line of the liner bag body is L, wherein 0≤L≤20 cm, or 0≤L≤0.1*D, where D is the minimum of lengths and widths of the front and rear panels;
• placing the liner bag in an intermediate bulk container, wherein the intermediate bulk container comprises a base and a side wall mounted to the base, the base is provided with a valve port where the discharge port of the liner bag is installed;
• arranging the liner bag in such a manner that after the liner bag is filled, a plane where the weld line is located is perpendicular to the base.
