Choose antistatic film for electronics processes

3M ET 40 is listed as an unprinted antistatic polyester film tape; 3M ET 40PR is the printed version. Both product families appear in different widths in the listing. If your workflow needs visible marking, examine the printed version; otherwise, the unprinted version may be an option. Selection also requires information about the component, surface and processing. The electrical behaviour of the finished bond depends on the complete application; the product name alone cannot determine it.

No. An antistatic film is not automatically an electrical insulating film. The listed products are assigned here because of their antistatic product classification. For an insulation task, check the data for products designed for that purpose and the conditions of your application. The insulating film page covers that separate selection question. State the electrical requirement explicitly in your enquiry so that the material and product review addresses the intended function.

A printed version is a relevant selection criterion when marking is needed during your handling or packaging step. The range lists 3M ET 40PR as printed and 3M ET 40 as unprinted. Check the width offered for the specific product and decide where the tape needs to be visible. Printing does not replace an assessment of the electrostatic requirements of the component or the full process.

Describe the component and its surface, the intended antistatic function, the required tape or part geometry and the process step. Also specify whether the printed or unprinted version is intended and how the material will later be removed. Krückemeyer GmbH uses these details to review which listed starting material and converting option fit the application. Cutting or die-cutting does not give the material additional properties; whether the finished part meets the required function must be checked for the specific application.
