Melt Pump for BOPP Film Extrusion Production Line
As a critical component in BOPP (Biaxially Oriented Polypropylene) film production, the plastic film extruder pump (also known as melt gear pump) has become indispensable for modern extrusion lines pursuing precision and efficiency. Installed between the extruder and die head, this positive-displacement device addresses the core pain points of traditional production by stabilizing pressure, metering flow, and boosting process stability.
In BOPP film extrusion, the plastic film extruder pump delivers three key benefits: first, it eliminates pressure pulsations to ±0.5% fluctuation, reducing film thickness deviation from ±5% to ±1.5% or lower ; second, its precise flow control (adapting to 2,000–12,000 kg/h output) supports high-speed lines (400–600 m/min) and ultra-thin film production (3–50 μm) ; third, it cuts energy consumption by 15–30% by reducing extruder load, extending equipment lifespan . Constructed with high-alloy gears (Hastelloy) and precision clearances (≤0.02 mm), it withstands temperatures up to 400°C and pressures of 250 bar, ideal for BOPP’s high-viscosity PP melt processing .
This equipment’s versatility shines in multi-layer co-extrusion and functional BOPP films, with modular designs supporting food-grade, metallized, and capacitor film production . Integrated with PLC systems and pressure sensors, it enables real-time monitoring, critical for maintaining consistent quality in large-width (8–12 m) BOPP lines . For manufacturers, investing in a specialized plastic film extruder pump is a strategic move to enhance competitiveness in the global BOPP market.
