    by：POLYVA     2021-11-14
    In order to make printing inks and composite adhesives have good wettability and adhesion on the surface of the plastic film, the surface tension of the film should reach a certain standard, otherwise it will affect the adhesion of the ink and adhesive on the surface. And adhesion, thereby affecting the quality of printed matter and composite products. For example, the surface tension of biaxially oriented polypropylene film and low-density polyethylene film is required to reach above 3.8E-2N/m, and the surface tension of nylon film, polyester film and polyester aluminized film is generally required to reach 4.5E-2N/m above. Generally speaking, the plastic film must undergo surface treatment before printing or laminating to increase its surface tension, so that it can be printed and composited smoothly.
