ADHESIVE LAMINATION CAPABILITIES

Many of the die cut parts Knowell Corporation manufactures require the lamination of an adhesive with two or more materials. Most common is the addition of pressure-sensitive adhesive (PSA) backing to another substrate, like sponge, foam, rubber, or films.

It is important, even critical, to accomplish this lamination without entrapping air or contaminates between the two substrates. Knowell Corporation is very experienced at adhesive laminating dissimilar materials for complex applications. Our adhesive laminating capabilities include:

  • Adhesive backing
  • Double and single-sided
  • Multi-layer
  • Dissimilar materials
  • Zoned
  • PSA composites

ZONED ADHESIVE LAMINATION

Zoned adhesive lamination describes a die-cut part with only partial adhesive coverage of a selected pattern. This is achieved through a process of converting: laminating materials together, precisely die cutting those materials, and pulling away the unwanted adhesive material from the finished part.

Zoned adhesive patterns are often required for filter and venting components. 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.

SOLUTION CASE STUDY: LAMINATED PORON® FOAM GASKET USED IN OUTDOOR CAMERA SYSTEM

Knowell Corporation created a gasket with zone laminated double-sided adhesive die cut to the specific shape required and provided on a roll, which streamlined the manufacturing process.
