There is also the misplacement of bag making, which is one of the common problems in bag making. The reasons for this problem are as follows.
1. The thickness of printing and composite materials is uneven, with flounces, swinging edges or depressions produced by materials.
2, printing or composite process temperature or tension, pressure instability, poor setting, resulting in raw material stretching or shrinkage;
3. During plate making, the concentricity of plate rollers is uneven, and the pasting of big head and small tail or electric carving mother film is not allowed to produce skew. Multiple pieces of electric carving plate making produce gradual skew phenomenon, resulting in bag making dislocation.
4. When making bags, the tension of the double floating rollers is too small (too large), or some rollers rotate unsteadily;
5. The tension is not stable or the discharge speed is too low when making bags;
6. The pressure on the left and right sides of the bag-making package specification board is uneven, and the tightness is improper;
7. Material moisture absorption deformation, poor working environment temperature and humidity;
8, the use of solvents containing alcohols when printing, residual solvents exceed the standard;
9. When compounding, the water content of ethyl acetate exceeds the standard.
10. Other reasons (equipment error reasons)
