Automatic 2-7 Layer Air Bubble Film & Bag Machine, Twin Screw, 100% Recycled LDPE

Product Introduction

The Seven-Layer Air Bubble Film Machine (Side Extruder Type) is a high-efficiency, fully automatic extrusion line engineered for the continuous production of multi-layer air bubble film and bubble bags. Designed around a twin-screw plasticizing system and an upgraded T-die, the line delivers stable melt flow, uniform thickness distribution, consistent bubble formation, and reliable winding quality—key requirements for long, uninterrupted industrial production. With multiple width configurations and bubble size options, it enables manufacturers to produce cushioning materials tailored to different protection grades, from lightweight wrapping to heavy-duty shock absorption. Optimized for LDPE-based formulations and compatible with 100% recycled LDPE, this system helps reduce raw material cost while maintaining dependable output and repeatable product performance, making it well-suited for modern packaging plants focused on productivity, quality consistency, and sustainable material utilization.

Product Features

2–7 Layer Structures for Customized Protection

Configurable from 2 to 7 layers, the machine supports flexible structure design to match diverse packaging needs. Multi-layer lamination improves impact resistance, cushioning resilience, and puncture strength, while maintaining stable thickness across the entire web. This allows producers to supply different market segments with a single production line, improving equipment utilization and product portfolio coverage.

Twin-Screw Extrusion + Newest T-Die for Stable Film Quality

The twin-screw configuration enhances material plasticizing and mixing efficiency, contributing to more stable extrusion and better dispersion when using recycled inputs. Combined with the newest T-die design, the line achieves improved thickness uniformity and smoother film surfaces, supporting consistent bubble geometry and roll appearance during extended production runs.

Wide Material Compatibility Including 100% Recycled LDPE

The line is compatible with LDPE, LLDPE, PP, and 100% recycled LDPE, enabling manufacturers to select materials based on performance targets, availability, and cost control. This flexibility supports recycled-content packaging initiatives while maintaining reliable forming behavior and finished-film cushioning performance for transport protection.

Inner Water Cooling for Reliable Forming at High Output

Inner water cooling strengthens forming stability by improving temperature control during bubble shaping. This helps reduce deformation, supports consistent bubble height and spacing, and enables stable production at 20–50 m/min across various film widths and bubble specifications—ideal for high-throughput operations requiring predictable productivity.

Full-Automatic Winding and Standardized Operation

The integrated full-automatic winder reduces manual handling, improves roll tightness and alignment, and supports consistent roll quality for downstream converting and packaging use. With an automatic operation design, the line helps standardize production, reduce operator workload, and enhance shop-floor efficiency, especially in continuous multi-shift environments.

Technical Specifications

Application Fields

The air bubble film and bubble bags produced by this line are widely used as protective packaging and cushioning materials in beverage, food, chemical, medical, machinery, and hardware industries. They are ideal for wrapping bottles, containers, instruments, spare parts, and other items that require shock absorption, scratch resistance, and secure unitization during warehousing and transportation. The multi-layer bubble structure helps reduce transit damage, improves packaging efficiency, and supports stable logistics performance for manufacturers and distributors handling both fragile and high-value products.
