Stretch Film Extrusion Machines: Controlling PIB Cling Layer
Advanced multi-layer stretch film extrusion machines—Semi-Automatic, 3-Layer, Fully Automatic, 5-Layer, and 2-Layer models—now offer precise control of PIB cling layers during co-extrusion. Optimized screw mixing ensures uniform distribution of low-molecular-weight polyisobutylene masterbatches within LLDPE matrices. This critical process dictates predictable post-extrusion molecular migration toward designated surfaces, enabling flexible switching between single or double-sided tack while preventing pallet adhesion and roll blocking.
