Application
PIPLL Blowing Film Extrusion Screw Barrels are engineered for versatile compatibility, powering a wide range of film blowing extruders. They are tailored to meet diverse production needs, including:
· Barrier Membranes: For PP, PA, EVOH, mLLDPE, LLDPE, and HDPE.
· Packaging Films: Suitable for LDPE, mLLDPE, LLDPE, PP, bipolymer PP, terpolymer PP, and other composite packaging materials.
· High-Barrier Shrink Films: Optimized for PA and EVOH.
· POF Shrink Films: Compatible with PP, PE, and PP-structured formulations.
· Geomembranes: Ideal for LLDPE, mLLDPE, LDPE, HDPE, and EVA.
· Agricultural Films: Supports LLDPE, mLLDPE, LDPE, HDPE, and EVA.
· High-Transparency Packaging: For mLLDPE, LLDPE, LDPE, and EVA.
· TPU Films: Dedicated to TPU film extrusion.
PIPLL Film Blowing Extrusion Screw Barrels are designed for demanding blown film applications requiring stable output, uniform plasticization, and consistent melt quality.
With optimized screw geometry, barrier sections, and customized mixing elements, PIPLL screw barrels can be configured for different film materials and production requirements, from standard packaging films to high-barrier, agricultural, geomembrane, and specialty films.
Excellent Melt Homogeneity
Optimized barrier and mixing sections promote uniform melting and melt homogenization, helping reduce unmelted particles and improve film consistency.
Stable Extrusion Output
A balanced feeding, melting, and metering design helps maintain stable melt pressure and consistent output during continuous film production.
Flexible Material Compatibility
The screw barrel can be configured for LDPE, LLDPE, mLLDPE, HDPE, PP, EVA, PA, EVOH, TPU, and other film-grade materials according to the application. These material and application ranges are already specified on PIPLL's current product page.
Optimized Mixing Performance
Customized Maddock, pineapple, or other mixing elements can be incorporated according to the material and required melt homogenization.
Controlled Shear & Temperature
Screw geometry is optimized to provide efficient melting while controlling excessive shear and melt temperature.
Wear-Resistant Options
Nitrided and bimetallic screw and barrel configurations are available for different materials, production conditions, and service-life requirements.
The barrier section separates solid and molten material during the melting process, improving melting efficiency and melt uniformity for demanding film extrusion applications.
Maddock, pineapple, and other mixing configurations can be selected according to material characteristics and the required level of distributive or dispersive mixing.
Grooved-feed barrel configurations can be matched with the screw design to improve solid conveying and support stable feeding for high-output film extrusion.
Screw length and L/D ratio can be customized according to resin characteristics, film application, output requirements, and extruder configuration.
Screw flight geometry, surface finish, straightness, and critical dimensions are controlled during machining to ensure reliable screw barrel performance.

PIPLL provides application-specific screw and barrel solutions rather than a one-size-fits-all design.
Our engineers can customize screw geometry, barrier section, mixing elements, L/D ratio, material, surface treatment, and barrel configuration according to the actual film extrusion process.
Whether you are replacing a worn screw barrel or optimizing an existing blown film extruder, PIPLL can develop a suitable configuration based on your extruder model, screw dimensions, film material, application, and target output.
Send us your extruder model, screw diameter, L/D ratio, film material, film application, target output, or original drawing.
PIPLL will evaluate your requirements and recommend a suitable screw barrel configuration for your film blowing extrusion line.
