The Problem for Converters
BBOPP / PET / PVC / LLDP / Laminate / Co polycarbonate crystalline ‐ the films of today can be devastatingly hard and abrasive. Modern lifestyle demands for high % recycling and bio-degradable films that will still withstand the temperatures of a modern oven or microwave. Basic steel blades are no longer able to offer the performance required; they lack the wear resistance and life expectancy needed in modern converting and their high coefficient of friction levels easily melts the films slit edge. However only the big corporate manufacturers running 24/7 can afford to use the modern blade materials, like tungsten carbide and zirconia ceramic, which are good but brittle and susceptible to breakage.
