Processing Recommendations
EVASIN EV4451 EVOH Resin is typically processed via multilayer co-extrusion, blown film, sheet extrusion and blow molding. Because EVOH is sensitive to moisture, pre-drying is recommended before processing.
In multilayer structures, EVOH is commonly sandwiched between polyolefin layers (PE or PP) using tie-layer adhesives to ensure adhesion and barrier performance.
