Product Description

Product Description

Three-Layer Co-extrusion IBC Internal Cooling Blown Film Machine (Model: ES-3-2800)

Our Three-Layer Co-extrusion IBC Internal Cooling Blown Film Machine (Model ES-3-2800) is a high-performance, high-precision blown film production line designed for manufacturing multi-layer films with superior thickness uniformity, excellent transparency, and outstanding mechanical properties.

This advanced blown film machine integrates internal bubble cooling (IBC) technology, precision extrusion control, and automated winding, making it ideal for producing high-quality LDPE, LLDPE, HDPE, and EVA films used in packaging, agriculture, industrial laminates, and more.

Key Features

High Efficiency & Stability

Advanced Co-extrusion Technology

IBC (Internal Bubble Cooling) System

Max Output: 500 kg/h, Max Film Width: 2600mm
Single-layer thickness range: 0.025 – 0.15mm, ensuring versatility for various applications.

Three-layer structure (outer/middle/inner) with precise material distribution.
Optional hydraulic screen changer for continuous production without downtime.

Ultrasonic bubble diameter control (±5mm accuracy)
Dual-speed fans (7.5KW each) ensure rapid cooling and stable bubble formation.

High-Quality Extruders

Precision Die & Air Ring

Fully Automated Winding

SJ90/30 (main) + SJ75/30 ×2 (auxiliary) extruders
38CrMoALA alloy nitride steel screw (30:1 L/D ratio) for superior plasticizing & wear resistance

Φ700mm optimized co-extrusion die (chrome-plated flow channels) eliminates material stagnation.
Taiwan-style dual-port air ring enhances cooling efficiency & film surface smoothness.

Dual-position friction rewinder with PLC tension control.
Max roll diameter: Φ800mm, auto-cutting, and edge trimming functions.

Smart Control System

 Durable & Low Maintenance

10.4" Touchscreen PLC with Delta frequency inverter
Ultrasonic edge guiding (Germany P+F sensor) ensures straight & tight rolls.

Hardened gears, precision reducers, and industrial-grade electrical components (Schneider) ensure long service life.
