Abstract
Die build-up is a persistent issue in plastic film extrusion, causing surface defects, product inconsistencies, and increased machine downtime. The use of Polymer Processing Aids (PPAs) is used in industry to reduce Die build-up. The aim of this study is to investigate the effect of PPA to reduce DBU during polypropylene (PP) cast film extrusion. In a first step, four different PP formulations with three manufacturing conditions are evaluated in order to get DBU. Then, in a second step, reduction of DBU is performed using the formulation with the highest DBU tendency with 1 phr and 3 phr PPA additives. Experimental results, observed over 30 minutes, indicate that the incorporation of 3 phr PPA significantly reduces DBU, improves film surface quality, and reduces the need for frequent equipment cleaning. The findings demonstrate the potential of PPA as a practical solution to enhance extrusion process stability and operational efficiency.
