What Problems Occur During the Operation of Bag Making Machines?
2026-09-29IP location 江苏常州 电信0

The bag making machine is equipment for producing various plastic bags, woven bags and other packaging materials. Common problems, causes and solutions:

1. Inaccurate bag size - causes: uneven feeding roller pressure, unstable feeding motor speed, wrong control system parameters; solutions: adjust the roller pressure evenly, check the feeding drive system for stable speed, and recalibrate the control parameters.

2. Weak sealing - causes: temperature set too low, sealing time too short, insufficient sealing pressure; solutions: raise the sealing temperature, extend the sealing time and increase the pressure accordingly.
