currently, large bags are often produced by hand-held machining, mainly for the following reasons:

1. because the liquid bag has larger volume and complex bagging process, the occupied area is larger when the machine is adopted for processing;

2. when the machine bagging is adopted, the PE double-layer cylindrical film needs to be paved on the workbench surface, so that the bagging has the following disadvantages:

(1) If the workbench is not clean, the sanitation of the liquid bag production is easily caused to be not up to the standard;

(2) If the working surface is uneven, the PE double-layer cylindrical film is easily scratched in the bagging process, and the sealing performance of the liquid bag is affected;
