1. Increase the viscosity of the label, as far as possible to make the label paste firmly.
2. The use of soft label materials as far as possible, good label ductility will also greatly improve the warping.
3. Change the shape of the label. The bottom of the label to make an arc, as far as possible to avoid sealing deformation area, of course, the arc can not open too deep, or because the label itself is easy to cause wrinkles, add unnecessary trouble.
4. Eliminate the impact of static electricity. Labeling process is easy to produce static electricity, this will have an impact on the labeling effect, appropriate to improve the humidity of the site, there will be a certain improvement, the use of ion blower is also an effective solution.
