Friable bales

A process to make a friable bale, wherein the friable bale is formed from a composition comprising coated polymer particles, which comprise polymer particles formed from a polymer composition comprising an olefin-based polymer, and a coating formed from a coating composition comprising an aqueous metal acid dispersion, and an aqueous polysiloxane emulsion, said process comprising adding the coated polymer particles to a baling machine to form the friable bale;

• and wherein the friable bale has a compression force ≤1.00 MPa.

The process of any one of the previous claims, wherein the weight ratio of the polysiloxane to the metal acid, in the coating, is from 0.15 to 0.50.

The process of any one of the previous claims, wherein the metal acid is present in an amount from greater than zero to 5000 ppm, or greater than zero to 2000 ppm, or greater than zero to 1000 ppm, or greater than zero to 500 ppm, or greater than zero to 300 ppm, based on the weight of the coated polymer particles.

The process of any one of the previous claims, wherein the metal acid is present in an amount from 20 ppm to 5000 ppm, or from 20 ppm to 2000 ppm, or from 20 ppm to 1000 ppm, or from 20 ppm to 500 ppm, or from 20 ppm to 300 ppm, based on the weight of the coated polymer particles.
