Producing high-quality LLDPE blown film demands precision. If your current screw struggles with gels, unmelted particles, or inconsistent melt, a custom barrier screw for LLDPE blown film can significantly enhance product quality and boost production efficiency. This specialized screw design addresses LLDPE’s unique processing challenges, ensuring a more homogeneous and gel-free melt.
Why LLDPE Needs a Specialized Barrier Screw
LLDPE’s rheological properties often cause gels and inconsistent melt with standard screws, impacting film clarity, strength, and throughput. A custom barrier screw is engineered to optimize melting and mixing, delivering a superior melt for blown film.
Custom Barrier Screw Design & Materials
Juyuan Machinery designs custom barrier screws with:
- Barrier Flight Design: Separates solids from melt, preventing gels.
- Optimized Mixing Elements: Ensures thorough melt homogenization for uniform film properties.
- Material Options: For standard LLDPE, a 38CrMoAlA nitrided screw offers durability. For LLDPE with additives (e.g., 2% slip agent) or recycled content, bimetallic alloys or wear-resistant coatings extend lifespan.
Benefits for Your Blown Film Line
Upgrading to a custom barrier screw delivers:
- Reduced Gels: Clearer, smoother films, cutting scrap.
- Increased Throughput: Higher output (e.g., a 65mm, L/D 30:1 custom barrier screw can significantly boost output).
- Enhanced Film Quality: Uniform thickness and improved mechanical properties.
- Longer Lifespan: Minimized wear reduces maintenance.
When to Request a Quotation
Consider a custom barrier screw if your LLDPE blown film line experiences:
- Frequent gels or black specks.
- Inconsistent film quality or thickness.
- Lower than desired production rates.
- Excessive screw wear.
