Overview
Tospearl 120FL is 2 micron size micro-fine silicone resin that is used as an additive in biaxially oriented polypropylene (BOPP) films as a slip and antiblocking agent. As a slip agent it improves the Coefficient of Friction (COF) to facilitate easier processing, faster line speeds and prevents the film from tearing.
Tospearl when used as a antiblocking agent prevents adhesion during film production both on a finished roll or on the inside of the bubble.
