PVC shrink film printing notes
1 overprint problem. PVC shrink film is very sensitive to the temperature, when printing, the oven temperature can not be too high, generally does not exceed 40 °C.
2 PVC shrink film is more sensitive to solvents, such as butanone and other highly soluble solvents can not be used, otherwise it will cause the film to dissolve and affect the printing quality.
3 The thickness deviation of PVDC film produced by blow molding process is relatively large, which easily causes uneven printing tension and affects the printing quality.
4 The PVDC film produced by the blow molding process does not have good plasticization of the crystal grains, which may cause missing dots and lack of ink on the printed products and affect the printing quality.
