Electrostatic charges develop on surfaces of film webs as they are transported through various converting processes such as rewinding, slitting, coating, laminating, bag making and sheeting. These charges often cause attraction of particulate to the web material and defects in printing and coating uniformity resulting in quality problems and customer dissatisfaction. Significant static charges can also cause operator shocks, interruption of process control electronics, fires in solvent coaters and reduction in machine speeds to overcome web transporting problems.

This paper will discuss the basic theory of static generation and the practical use of ionizing equipment to control charges to a manageable level. This will result in reduced down time, safer operating conditions, higher productivity and enhanced product quality.

Ionizers are critical to the web handling process, controlling electrostatic charges to enhance product quality and throughput. In solvent coating and printing processes, they are critical to safety, reducing the chance of fires and explosions.

All ionizers require periodic cleaning and performance verification, but this is rarely done due to lack of understanding of the importance and little knowledge of the ionizers and how to evaluate and service them. New technology ionizers solve these problems, offering constant monitoring of system operating status and performance. Local display or remote computer display indicates when maintenance is required.

The plain brown box isn’t what it used to be! Today, corrugated boxes are used to sell the products they protect. In some instances, the box costs more than the product. Slitter dust, chaff from sheeting, and other environmental contaminants on the surface of the material make it impossible to achieve production goals, and difficult to maintain quality print standards set by the customer.

Learn more about cleaning corrugated material from this article that appeared in Package Printing Magazine.
