High-Efficiency 7-Layer Bubble Film Machine for Premium Insulation and Industrial Packaging

Manufacturers in the insulation and protective packaging industry are increasingly looking for equipment that delivers stable output, reduced labor demand, and consistent multi-layer film quality. The 7-layer composite Air Bubble Film Extrusion Machine is designed to meet these requirements with advanced extrusion technology and a fully automated production system.

This machine is widely used to produce insulation bubble film, reflective insulation materials, industrial cushioning film, cold-chain packaging, and other high-performance products.
 

Advanced Triple-Screw Extrusion for High-Quality Multi-Layer Output

A major advantage of this machine is its triple-screw extruder configuration, allowing the operator to run multiple material formulations at once. Each screw is engineered for:

- Uniform melt mixing
- Stable extrusion pressure
- Excellent temperature distribution
- Improved bonding between composite layers

The result is a stronger and more durable 7-layer bubble film with better insulation capability and air retention.
 

Three Extrusion Die Heads for Stable Layer Distribution

The machine features three precision-engineered extrusion die heads, ensuring optimal flow and accurate layer arrangement during film formation. This design provides:

- Enhanced consistency for each film layer
- Reduced thickness deviation
- More stable bubble formation
- Improved resistance to puncture and compression

This makes the product suitable for demanding applications in construction insulation and long-distance logistics.
 

Integrated Edge Trim Recycling System for Cost Control

To reduce production waste, the line includes a built-in edge trim recycling system. The system immediately reprocesses scrap film and reintegrates it into the extrusion cycle. Key benefits include:

- Lower raw material usage
- Continuous production efficiency
- Cleaner working conditions
- More sustainable manufacturing
 

Automatic Cutting, Rewinding, and Roll Change for Operator-Free Production

The downstream section of the machine is fully automated to support 24-hour production:

- Automatic cutting ensures each roll is precisely separated
- Automatic rewinding forms tight, uniform rolls with stable tension control
- Automatic roll changing eliminates downtime and avoids manual handling

This level of automation significantly reduces labor dependence and increases production stability.
 

PLC Control System for Easy and Accurate Operation

The entire line is centrally managed by a PLC control system, which provides:

- Real-time monitoring of temperature, pressure, and speed
- Automatic adjustment to maintain consistent quality
- Fault detection and safety alerts
- Easy recipe switching for different bubble film specifications

Even new operators can manage the production line efficiently with the intuitive interface.
 

Applications of 7-Layer Composite Bubble Film

The 7-layer bubble film produced by this equipment is ideal for:

- Construction thermal insulation
- Air duct insulation and reflective systems
- Cold-chain packaging and food transport
- Precision instrument protection
- Export packaging and logistics cushioning

Its superior insulation, compression strength, and long-lasting air sealing make it an excellent choice for high-end markets.
