Commonly used plastic films are: PE, PP, PVC, PS, PVA, PC, PET, CA, NY. The printing characteristics of these plastic films are:
â‘ Plastic film is a non-polar polymer compound, which has poor adhesion to printing ink. In order to make the plastic film surface have good ink adhesion and enhance the firmness of the printed product, surface activation treatment is performed before printing:
â‘¡The hygroscopicity is mostly affected by the relative humidity of the surrounding air and expands and contracts, resulting in poor overprinting;
â‘¢Due to the change of tension, in the printing process, in the allowable range of strength, the elongation rate increases with the increase of tension, which makes the accuracy of color printing overprint difficult:
â‘£The surface is smooth, there is no capillary holes, the ink layer is not easy to fix or is not fixed firmly, after the first color is printed, it is easy to be stuck by the ink of the next color overprint, which makes the pattern and text incomplete and causes defects;
⑤ The oil layer on the surface oozes out. Films made with additives can easily bleed out during the printing process, forming an oily layer, ink layer, paint or other adhesives on the surface of the film.
â‘¥Since the plastic film is a non-polar material, there are no capillary holes, and the ink is not easy to dry. These characteristics are not conducive to printing, so the plastic film must be surface-treated before printing.
