EVA films are soft, transparent, low-temperature resistant, and offer excellent adhesion. They are widely used in footwear, packaging, solar encapsulant films, and agricultural mulch. Good plasticization and low gel content are essential for high-quality film. PIPPL conical twin screws with enhanced mixing sections and dual-alloy barrels deliver uniform VA distribution and gel-free melt for reliable EVA film production.
Key Features
• Enhanced mixing sections on conical twin screw ensure uniform VA distribution across different EVA grades.
• Low-shear design minimizes gels and thermal degradation.
• Dual-alloy barrel provides excellent wear resistance for filled or recycled EVA formulations.
• Fast self-cleaning reduces cross-contamination between different VA-content runs.
• Stable output for consistent film thickness and optical quality.
Product Types
Packaging films, solar encapsulant films, adhesive films, and agricultural mulch films with various VA contents and thicknesses.
