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.
Bandera – Extrusion Intelligence® is participating at NPE Plastics Show 2024, Fortisblades is a proud partner and is available at the Bandera booth to meet customers and give advice in slitting. The razorblade serves as the final point of contact in the production process, critically defining the quality of the final plastic roll. Make sure every element in your extrusion line is of the highest quality.
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.
Implementing safety guards as physical barrier to address safety hazards is a great way to ensure the correct handling of industrial razorblades. At Fortisblades we designed our packaging with safety in mind, forcing the operator to handle the blade in a safe way.
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.
