Abstract

The invention discloses a process for agglomerating a fluff comprising one or more polymer(s), optional fines, and optional additives, said fluff having a high load melt index (HLMI) of from 0.1 to 20 g/10 min, by submitting said fluff to a mechanical force under a temperature sufficient to soften and deform the polymer grains.
