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.
TTR stands for 'Thermal Tranfer Ribbons' and are widely used in label printers. These ink ribbons are cut from a thermal-transfer ink mother film. Many colours and in general 3 qualities are available: wax, wax resin and resin.
The plastic film processing industry participates in the circular economy to reduce the environmental foot print. Many new film products are produced with substantial content of recycled plastics.
Well engineered agricultural mulch films and bale wrapping stretch films have become increasingly important. Fierce competition in these films market has led to stronger films in terms of mechanical performance and lifetime. All efforts to produce excellent films can be lost due to poor slitting (high reels, breaking of the web and jagged edges).
Is the excessive wear of blades due to mineral TiO2 familiar to you?
We are daily challenged by the innovations and problems in the film and foil industry to develop a cutting tool that corresponds to the requested properties of the film, to highest outputs and lowest manufacturing costs.
Film slitting is critically important in film production, especially with state-of-the-art tough films. When performed well, slitting can provide smooth winding and less wrinkling of film. However, poor cuts can generate a series of many negative effects.
