An investigation into the phenomenon known as “bagging” on a rubber mill was made. Based upon the assumption that bagging is a manifestation of a viscoelastic hydrodynamic instability, a scale‐up criterion for the onset of bagging was developed. The derived scale‐up method was tested over wide ranges of elastomer compounds and mills and found to hold within the estimated experimental error.
