During processing, polyolefins often stick to themselves or to a metal surface. A desirable friction coefficient for polyolefins in solid form typically lies between 0.15 and 0.35 In day-to-day production, however, the steady state form of polyolefin films rarely achieves this coefficient value.

Polyfil offers a wide array of migratory and non-migratory slip masterbatches that can help flexible packaging manufacturers meet and keep their COF targets over time, even after lamination.
