Film is a kind of plastic, belonging to polymer materials, is widely used in the modern packaging industry, used for moisture-proof, some are directly made into a film to wind and disturb the goods, to avoid the goods in the process of transportation by the rain, some are made into plastic bags, printed with text patterns, used to promote their own brand, can also be made into tape paper, used to package, tape paper can also be printed on their own trademarks and logos, used for identification.
When producing the film, or when printing on the surface, static electricity often occurs, especially in autumn and winter, because the air is dry, and the film is a polymer material, with strong insulation performance, so under the action of friction, a large amount of electrostatic charge will be generated when printing, slitting and winding, and the electrostatic charge will form static electricity if it cannot be dissipated in time, which will affect printing and film production.
When the film is printed, the influence of static electricity is mainly manifested in the adsorption of dust, ink layer adhesion, ink color transfer, electrostatic ink spots, ink whiskers, etc., which will make the text pattern blurred, and will also lead to film adhesion, rewinding, and difficulty in separating. Seriously affected the quality of printing, although it will not affect the packaging function, but the impact on the brand of the enterprise is still there, you are a large enterprise, the printed tape paper is blurred, it can be seen that the product quality is not good, which will give consumers a negative impression.
For companies that produce thin films, the impact of static electricity is mainly manifested in the impact of winding, cutting error, dust adsorption and static electricity. Due to the influence of static electricity, it will cause abnormalities such as film winding or wrinkling during winding;The finished film sheets are either attracted to each other or repel each other, and it is difficult to tidy up, which will cause cutting errors;Static electricity will absorb a large amount of dust on the surface of the film, which will affect the cleanliness of the film product and the subsequent processStatic electricity can lead to employee errors and accidents. Therefore, it is recommended to use ZS-80Z series anti-static humidifier to eliminate and prevent static electricity.
ZS-80Z series anti-static humidifier adopts ultrasonic oscillation atomization technology, which can atomize water into 1-10 micron particles, and the air humidity can be increased after the mist particles are quickly vaporized, and the microcomputer control system can control the air humidity between 60-65%RH, which can not only eliminate the electrostatic charge on the surface of the film, but also spray directly on the surface of the film to achieve the purpose of eliminating static electricity. Film printing is not affected by static electricity.
