(2) The error between the pre-adjusted film feeding length (when adjusting blank bag) and the actual bag-making size is too large, so the line making length should be reset or the pressure should be adjusted and the device adjusted.

(3) The film resistance is too large or the quality of the previous process is poor, the material should be checked and replaced.
