Slitting Pearlized Film for Flexible Packaging
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.
