Barrier Film: Selecting Shielding Materials

It shows products classified as “shielding” in the catalogue, including copper foil tapes and tapes with other backings. This classification does not automatically mean they form a barrier against moisture or gases. If your application requires such a barrier, the property must be documented for the specific product and intended construction. Tell us what the component needs protection from and how the material will be processed.

That cannot be inferred from a “shielding” classification alone. Electrical or electromagnetic shielding and a barrier against moisture are different requirements. The particular material, its construction, adhesive layer and conditions on the component all matter. Selecting a barrier film therefore requires suitable product evidence for the required protective effect. Without that evidence, the claimed property should not be extended to the finished component.

The catalogue includes copper foil tapes with both conductive and nonconductive adhesives. That distinction matters when an electrical connection is required through the bonded surface; the foil backing alone does not fully describe contact at the component. Check the specific product, the intended contact path, the substrate and the processing method. Whether a shielding design works depends on the complete application and cannot be promised from the product category alone.

State the required protective function, component, substrate, desired shape and planned processing. Krückemeyer GmbH can cut suitable source material and produce die cut parts; whether a particular shielding material is suitable depends on its construction and geometry. A moisture or gas barrier also requires product specific evidence of the required performance. This separates the choice of material from the choice of supplied format.
