## Abstract

A liquid transport system, a liner bag and a method of using the same are disclosed. The liquid transport system includes a intermediate bulk container and a liner bag, wherein the intermediate bulk container includes a base and a side wall mounted to the base, the base is provided with a valve port, and the liner bag includes a liner bag body and a discharge port. The liner bag body is formed by hermetically welding a front panel and a rear panel along the periphery thereof, and the discharge port is hermetically connected to the liner bag body, and the distance between an edge of the discharge port and a weld line of the liner bag body is set to a minimum. The liner bag is placed in the intermediate bulk container and the discharge port of the liner bag is installed in the valve port.

## Claims

### Claim at position 1

1-15. (canceled)

### Claim 16

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, wherein the discharge port is hermetically connected to the liner bag body, and a 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.

### Claim 17 (depends on 16)

The liner bag according to claim 16, wherein the front panel and the rear panel are rectangular flexible sheets.

### Claim 18 (depends on 16)

The liner bag according to claim 16, wherein a minimum distance S between the discharge port and a corner of the liner bag body is greater than 20 cm.

### Claim 19 (depends on 16)

The liner bag according to claim 16, wherein a primary weld line is formed around the liner bag body and an secondary weld line is also formed between the at least two primary weld lines, and is connected to the two primary weld lines.

### Claim 20 (depends on 16)

The liner bag according to claim 16, wherein at least one side of the liner bag body includes at least two sections of weld lines which are connected to each other at an angle.

### Claim 21 (depends on 20)
