Fully Automatic 7-Layer Air Bubble Film Machine for Recycled LDPE, High-Speed Production

Seven-Layer Air Bubble Film Machine (Side Extruder Type)

The Seven-Layer Air Bubble Film Machine (Side Extruder Type) represents a pinnacle in automated production technology, engineered specifically for the high-volume manufacturing of superior multi-layer air bubble film and bubble bags. This advanced system guarantees exceptional product consistency, characterized by stable film thickness, uniform bubble formation, and flawless roll winding. At its core lies a robust twin-screw extrusion system paired with a state-of-the-art T-die design, offering unparalleled flexibility in film width and bubble configuration. Optimized for LDPE-based polymers, including 100% recycled LDPE feedstock, this production line empowers manufacturers to achieve significant material cost savings without compromising on output quality or the essential cushioning properties of the final protective packaging.

Product Features

Enhanced Multi-Layer Construction: Offering configurable production from 2 to 7 layers, this machine creates films with significantly improved structural integrity. The multi-layer design dramatically enhances impact resistance, puncture strength, and overall cushioning performance compared to single-layer alternatives, allowing for tailored solutions that meet packaging demands ranging from lightweight to heavy-duty industrial protection.

Advanced Extrusion and Die Technology: The integrated twin-screw extrusion system ensures highly efficient plasticizing and homogeneous material mixing, leading to stable melt flow and consistent film quality. Complemented by the latest T-die technology, the machine achieves precise and uniform thickness distribution across the entire film width, ensuring reliable and stable performance during extended, continuous production runs.

Versatile Material Compatibility: Designed for operational flexibility, the machine is fully compatible with a wide range of materials including LDPE, LLDPE, PP, and notably, 100% recycled LDPE. This broad compatibility provides manufacturers with diverse sourcing options, supports sustainability initiatives, and enables the production of cost-effective, eco-conscious packaging without sacrificing performance.

High-Efficiency Cooling and Output: The incorporation of an inner water cooling system stabilizes the bubble forming process, ensuring consistent product quality. This efficient thermal management supports high-speed production with an output range of 20 to 50 meters per minute, delivering dependable productivity across various film widths and bubble specifications.

Fully Automated Operation: The production line integrates a fully automatic winding system, which minimizes manual intervention, enhances roll consistency and quality, and boosts overall floor efficiency. The high degree of automation standardizes the production process, reduces labor intensity, and contributes to a more streamlined and reliable manufacturing operation.
