Name: Three layer co-extrusion film blowing machine | max. roll width 1200 mm
SKU: 2102
Availability: PreOrder

⚙️ Production Overview

The three-layer co-extrusion film blowing system is designed for continuous manufacturing of multilayer polyethylene film with stable thickness and uniform structure. It supports a maximum film width of 1200 mm and produces LD film within a thickness range of 0.015–0.15 mm. Output capacity can reach up to 140 kg/hour depending on raw material type and processing formula, ensuring steady industrial performance.

⚙️ Compatible Materials

This equipment processes LDPE, LLDPE, EVA, and HDPE polymers. It is suitable for producing packaging film, lamination layers, protective sheets, industrial wrapping film, agricultural film, and flexible bag materials. The multi-layer extrusion process allows combining different materials to improve strength, flexibility, and barrier properties in the final product.

⚙️ Extrusion and Die Structure

The extrusion die for LD material features a diameter of ϕ250/300 mm, enabling balanced melt distribution and stable bubble formation. The co-extrusion configuration maintains uniform layer bonding and supports consistent film quality across long production cycles. This setup ensures reliable thickness control and smooth output during operation.

⚙️ Winding System

A surface-friction double winder is installed for accurate roll formation. The roller width reaches 1300 mm, and the winding motor rated at 16 N·m provides stable tension control. Rewinding speed is adjustable between 5–60 m/min, allowing operators to adapt to different film thicknesses and production requirements.

⚙️ Power and Series Options

The machine operates on 380 V / 50 Hz / 3-phase electrical supply. Making it suitable for industrial installation. Within this series, other models are available with different technical parameters and price levels. These variations allow manufacturers to choose the configuration that best matches production capacity, material type, and budget.

🏭 Machine Overview
The three-layer co-extrusion film blowing system is built for industrial multilayer film production with consistent thickness and high output stability. It delivers a maximum film width of 1200 mm and operates within a thickness range of 0.015–0.15 mm, making it suitable for flexible packaging and technical film manufacturing. The production capacity can reach up to 140 kg/hr depending on raw-material formulation. Powered by 380 V / 50 Hz / 3-phase, the machine supports continuous high-volume operation in modern factories.

🧪 Compatible Materials
This equipment processes LDPE, LLDPE, EVA, and HDPE resins. These materials are widely used for manufacturing shopping bags, food packaging films, shrink films, agricultural covers, protective sheets, and multilayer industrial liners. The extrusion die size of ϕ250/300 mm ensures balanced melt distribution across all three layers, improving tensile strength, transparency, and sealing performance.

⚙️ Winding & Performance
The surface-friction double winder allows stable roll formation with minimal downtime during roll changes. With a roller width of 1300 mm and a winding motor rated at 16 N·m, the system maintains steady film tension. Rewinding speed ranges from 5–60 m/min, enabling efficient roll collection and consistent film quality during long production runs.

🏢 Application Fields
This line is suitable for plastic packaging factories, agricultural film plants, food-packaging suppliers, retail bag manufacturing, and industrial sheet production. Businesses producing large-scale film rolls benefit from the 1200 mm width capacity and multilayer structure that improves durability and barrier performance. It supports operations producing several tons of film per day.

💡 Series Options & Differences
Other machines in the same series are available with different outputs, die sizes, and automation levels. Technical specifications and pricing vary depending on configuration and production capacity. Manufacturers can choose a model that aligns with material requirements, daily output targets, and investment planning for long-term efficiency.
