Professional screw barrel for LDPE, LLDPE, and mLLDPE blown film extrusion lines. Uniform melting, stable bubble formation, and high output efficiency.
Vanwell blow film screw barrels are specifically engineered for high-speed blown film extrusion lines. The screw design features a low compression ratio and shallow flight depth to handle the high shear requirements of LDPE, LLDPE, and metallocene LLDPE (mLLDPE) materials.
Our blow film screws deliver uniform melt distribution, stable bubble formation, and consistent film thickness control across the full width of the die. Available for monolayer and multi-layer coextrusion lines from small bags to industrial stretch wrap applications.
Optimized compression ratio for gentle material processing and uniform melt.
Specialized barrier flights ensure even melt distribution across the die width.
Wear-resistant barrel for long life with abrasive fillers and recycled materials.
Optimized screw geometry enables high throughput with lower energy consumption.
Handles mixed recycled plastics with stable performance and minimal wear.
Fits W&H,莱芬, Reifenhäuser, and other standard blown film lines.
Independent temperature zones for precise melt temperature control.
tight manufacturing tolerances for minimal clearance and maximum efficiency.
