The demand for toothbrushes made of biologically renewable raw materials to protect the environment has increased significantly in recent years. However, it‘s difficult for existing wire geometries to meet the tuft retention requirements for these new renewable materials. Enter a new anchor wire for bamboo toothbrushes from the market leader bedra: bercobrush® arrow.
Our innovative design dramatically improves tuft retention, exceeding industry requirements by more than 100%. Due to the arrow-like shape of the anchor wire, the wooden bamboo fibers are displaced smoothly during the punching process. The fibers then relax and distribute themselves into the interstices of the wire, delivering the increase in tuft retention.
The dimensions for bercobrush® arrow are 2.00 x 0.30 mm. Closest tolerances, high tensile strength and reproducibility are certainly standard. On request we also develop wires to your specific requirements.
