A. Irregular folding is mainly due to the large gap between the channels and the packaging material is difficult to close to the packaging object. The packaging material exceeds the packaging object more than the packaging object, and there is irregularity.
B. The parts used for folding are not installed well, deviated or not in place, causing the material to fail to be folded in place according to the predetermined requirements, and the deflection causes the product to fold irregularly.
C. The braking force of the packaging material is too small, and the film is slack when the film is stretched.
D. The packaging speed is too high, causing the packaging to shift during the transfer process.
