Polymers have a tendency to stick to one another during processing.

In film extrusion, the adhesion between film layers (called blocking) occurs during processing and when plastic films are wound onto and off film rolls.
Film surfaces, copolymers, static electricity, corona treatment, high temperatures, high pressure during winding and during storage - all of these have an influence on blocking capabilities.
Kafrit offers a wide range of solutions with varying particle sizes and different characteristics to assist with the above and improve your performance.
