7-Layer Composite Bubble Film Machine with Triple-Screw Extruders and Full Automation for High-Performance Insulation Film

The global demand for high-strength insulation bubble film and advanced protective packaging is rapidly increasing. To meet these requirements, manufacturers are turning to upgraded equipment such as the 7-layer composite Bubble Wrap Manufacturing Machine, specially engineered with three extruders, three extrusion die heads, and a fully automated downstream system. This production line combines high output, stable operation, and excellent product quality, making it ideal for factories targeting professional-grade insulation materials.
 

Triple-Screw Extruder System for Precise Multi-Layer Structure

The machine features three independent screw extruders, each designed to process different resin formulas. This configuration offers advantages such as:

More precise material temperature control
Flexible layer formulation for barrier, strength, and insulation
Consistent and stable melt flow
Improved bonding between the 7 layers

The triple-extruder layout ensures each layer contributes effectively to bubble strength, insulation, and long-term air retention.
 

Three Extrusion Die Heads Ensure High Output and Uniform Bubble Formation

The line incorporates three extrusion die heads, allowing the 7-layer composite structure to be formed with exceptional accuracy. This design ensures:

Uniform layer thickness
Stable bubble formation
Higher tensile and compression resistance
Enhanced thermal insulation performance

This makes the machine suitable for producing construction insulation bubble wrap, reflective insulation film, cold-chain packaging, and other industrial-grade products.
 

Full Automatic Cutting, Rewinding, and Roll Change for Continuous Production

To support uninterrupted production, the 7-layer bubble film machine includes a fully automated finishing section:

Automatic cutting provides clean and precise separation of film rolls
Automatic rewinding ensures tight, uniform rolls ready for shipment
Automatic roll changing keeps the machine running continuously without manual intervention

These features significantly reduce labor intensity while boosting productivity.
 

Edge Trim Recycling System Reduces Material Waste

The production line integrates an edge trim recycling unit, which immediately crushes and feeds scrap material back into the extruder. Benefits include:

Lower material consumption
Cleaner working environment
Improved extrusion stability
Reduced overall production cost

This system ensures efficient, cost-effective, and environmentally friendly manufacturing.
 

PLC Intelligent Control System for Stable and User-Friendly Operation

The machine is fully operated through a PLC intelligent control panel, which provides:

Real-time temperature and pressure monitoring
Automated parameter adjustments
Production data tracking
Fault detection and safety alerts

The PLC system helps operators manage the entire line easily, ensuring stability and high repeatability.
 

Applications of 7-Layer Composite Bubble Film

Thanks to its excellent structure, the final product is widely used in:

Building insulation materials
HVAC reflective insulation
Export packaging
Industrial cushioning
Cold-chain protection
E-commerce and logistics

The film produced offers superior insulation, strong puncture resistance, excellent compression strength, and long-term air retention.
