Fibrillating tape (also known as fibrillated tape or fibrillated yarn) is a specialized form of plastic tape that has been mechanically or pneumatically processed to create a network of interconnected fibers, resulting in a mesh-like or net-like structure. Unlike flat tape, which remains as a solid, continuous strip, fibrillated tape splits into a fibrous network when twisted or stretched, giving it properties similar to natural fibers .

The term “fibrillation” comes from the Latin word fibrilla, meaning small fiber. In the context of plastic extrusion, fibrillation refers to the process of deliberately creating a structure of interconnected fibrils (tiny fibers) from a solid plastic tape .

Fibrillating tape (fibrillated tape) is a specialized plastic tape with a mesh-like, fibrous structure used primarily in applications where high knot strength, flexibility, abrasion resistance, and durability are essential. Unlike flat tape, which remains as a solid strip, fibrillated tape splits into a network of interconnected fibers when twisted, making it ideal for twisting into ropes, twine, and cordage .

fibrillating tape machine (or extrusion line) is a comprehensive system composed of several integrated components. Each part plays a specific role in the continuous process of converting raw plastic granules into a finished, fibrillated tape product.
