noppen

Noppen is the Dutch word for bumps or protrusions on a surface. The term is used across everyday language to describe small rounded or conical elevations that serve protection, grip or cushioning. Noppen can be found on many materials and products, and the specific form and function vary by context.

One common use is in sports footwear, where noppen refer to studs on the outsole of shoes such as football boots. These noppen provide traction and stability on different surfaces, including natural grass and artificial turf. The design distinguishes between conical and bladed studs, and between molded noppen and screw-in or modular systems.

Noppenfolie, literally bubble or air-noppen film, is a packaging material with evenly spaced air-filled bubbles that cushion items during transport. The noppen create a layer of air that dissipates shocks and protects fragile goods. It is usually made of polyethylene and comes in various bubble sizes and thicknesses.

Noppen appear on a range of products for grip and texture. For example anti-slip mats and some tires or vehicle components have noppen to increase grip or to channel liquids. In textiles and surfaces, noppen can describe raised textures or patterns that provide tactile feedback or improved grip.
