Fortisblades specializes in providing high-quality industrial blades for various machines used for medical tube cutting. With extensive experience in this field, Fortisblades ensures that the industrial blades meet the highest standards of precision, durability and performance.
Film tape yarn is a type of yarn that originates from extruded polymer films, slit into narrow tapes. Film tape slitting requires precision to ensure the integrity of the tapes and the quality of the final product. Razor blades used in slitting film tapes can be compromised due to the abrasiveness of the material and (mineral) dust may form on the cutting edge of the blade. Thanks to our experience in the field of film tapes, we provide these blade categories to precisely align with your specific requirements.
Antiblocking agents are additives incorporated into plastics to prevent the adhesion of film layers. The typical silicon dioxide (SiO2) materials are effective antiblocking agents for plastic films. These additives have substantial impact on blade wear, slit quality and lifetime.
Pearlized or pearlescent films are often used in packaging and decorative applications. The presence of calcium carbonate (CaCO3) and pearlite pigment serves to achieve the desired visual (white, opaque and pearlescent appearance) and performance characteristics. The film is abrasive due to the presence of CaCO3, so it's crucial to choose cutting tools and parameters that can withstand such abrasion.
When it comes to PCR shrink foil, it's important to note that slitting this material poses certain challenges that may not be encountered when working with standard shrink foil. Fortisblades has found that our Fortis+ products have the best qualities to tackle these challenges.
Titanium dioxide (TiO2) pigments present a significant but addressable cause of industrial blade wear. Engineered for optimal performance across various types, film thicknesses, and operational speeds, we provide three blade categories to align with your requirements.
We initiated a study on film slitting to confirm the impact of blade choice on slit quality. It was found that the performance of the various types of blades seemed to decline over time as the appearance of dust particles and the “postage stamp” effect increased during the hourly inspections.
Breakage of zirconia ceramic razorblade during the slitting process is to be avoided at all cost. The solution may lie in the choice for blades with more resilience like Fortis or Fortis + .
Fortisblades found a solution for slitting Kraft paper with a 40 µm thickness, all while maintaining the more simple free cut like that of a razorblade. The result: we realise a 30 times longer lifespan without web breakage with the Fortius TC blades.
