After the bag type filling of the printing ink is adopted, the end user who uses the printing ink only needs to use one hand-operated two-roller extruder, and the residual printing ink in the aluminum-plastic composite packaging bag can be cleaned at one time, so that the time, the labor and the labor are saved. Experiments prove that the residual amount of the ink in the bag is less than 0.01 percent after the ink is cleaned by the two-roller extruder, and compared with the traditional barrel-type packaging ink cleaning mode, the residual amount of the ink is greatly reduced.
