Abstract: In order to meet the increasing requirements of the electromagnetic shielding, the principle and manufacture process of a film-taped metallic mesh were introduced and the influence of the parameters (such as the line width, period, duty ratio,et al) on optical and electromagnetic features were analyzed. By using the flexographic printing technology, the metal mesh film with the line widthes of 20, 30, 40 m and the periods of 300, 400 m on PET substrate were made, and the maximal electromagnetic shield effectiveness was more than 15 dB, while the UV-Vis transmission of metallic mesh on PET substrate was between 70% and 80%. The results indicate that the optical and electrical performance of metallic mesh film is inconsistent, and it is better to select a thinner line width and smaller period to obtain optimal shielding effectiveness.
