2–3 Layer Air Bubble Film Machine (Side Extruder Type)
The 2–3 Layer Air Bubble Film Machine (Side Extruder Type) is engineered for continuous, stable, and high-efficiency production of protective cushioning film used in modern packaging and logistics. Designed to run LDPE, LLDPE, PP, and even 100% recycled LDPE, this line combines a twin-screw extrusion system with a latest-generation T-die to achieve consistent melt plasticization, smooth film forming, and uniform bubble structure. With selectable film widths from 1250mm to 4000mm and production speeds of 20–50 meters per minute, it supports both standard roll formats and extra-wide industrial demand. Inner water cooling accelerates shaping and improves thermal control, while a fully automatic winder helps deliver tight, even rolls with reduced operator intervention—ideal for manufacturers seeking reliable output, repeatable quality, and lower production variability across long running cycles.
Product Features
Twin-Screw Extrusion for Strong Mixing and Process Stability
The twin-screw configuration enhances material mixing, melt homogeneity, and pressure stability, which is especially valuable when processing recycled LDPE or variable feedstock. This design helps reduce fluctuations in film quality and supports steady extrusion behavior in demanding production environments.
Newest T-Die Design for Uniform Thickness and Clean Appearance
The upgraded T-die structure is optimized to improve thickness distribution and flow balance across the web. This results in more consistent film gauge, improved surface appearance, and dependable bubble-forming performance—key factors for cushioning efficiency and customer-facing packaging quality.
2–3 Layer Bubble Film Structure for Better Protection and Customization
Supporting 2 to 3 layer constructions, the machine enables manufacturers to enhance cushioning performance, puncture resistance, and overall durability. Multi-layer capability also provides flexibility to optimize material cost, adjust protection level, and tailor product specifications to different end-use requirements.
Wide Range of Film Widths for Standard and Extra-Wide Production
Multiple width options—1250mm, 1500mm, 1600mm, 2000mm, 2500mm, 3000mm, 3500mm, and 4000mm—allow the line to serve diverse markets. From conventional packaging rolls to oversized protective sheets for industrial components and pallet wrapping, the system can be configured to match target output and application scenarios.
Inner Water Cooling for Faster Forming and Stable Bubble Shaping
Inner water cooling improves heat dissipation during bubble formation, enabling faster shaping and more stable bubble geometry at higher speeds. With an optional 20–30HP chiller configuration, the cooling system maintains consistent thermal conditions to support long-duration operation and reduce the risk of deformation, uneven bubbles, or film instability.
Automatic Winding and Multiple Drive Configurations
A fully automatic winder enhances roll build quality, improves winding consistency, and reduces labor dependence. To align with different factory standards and maintenance preferences, the production line can be configured with electric, mechanical, pneumatic, or hydraulic driven types while maintaining an automatic operating grade for improved overall efficiency.
Global Service and After-Sales Support
Comprehensive after-sales support is available, including overseas engineer assistance, on-site installation, commissioning and training, video technical support, and field maintenance and repair services. This service structure helps shorten ramp-up time, improve operational confidence, and maintain stable performance throughout the equipment lifecycle.
