Zoned Adhesive Lamination

Zoned adhesive lamination describes the process of laminating a selective pattern of PSA (pressure sensitive adhesive) onto another material to achieve a specific function. This occurs through a process of conversion - laminating materials together, precisely die cutting those materials, and pulling away the unwanted PSA material from the finished part.  

Zone-Coating

Zoned adhesive patterns are often required for filter and venting die cut components. As you can see in this image, the mesh is cut into a circle while the adhesive is cut into a ring, which allows air and sound to flow through the center of mesh.  

 

 

Many applications require filters and vents to act as barriers to dust, dirt, and moisture to protect the components within the product while allowing air and sound to pass. The precise zone of adhesive allows for secure bonding while also allowing the filter or mesh to function appropriately.  

Check out the various layers in the diagram below. Each layer is cut precisely and laminated together, including the zoned adhesive. The final part is used in an acoustic speaker.
