Three-layer Co-extrusion Blow Film Machine

The three-layer co-extrusion blow molding machine is a high-end plastic film manufacturing equipment that integrates efficiency, stability, and multifunctionality. It adopts advanced three-layer co-extrusion technology, precisely combining three different types of polymer materials (such as virgin material, recycled material, and color masterbatch) in a molten state to blow mold a composite film with special functional structures in one step. This equipment is widely used for producing high-end packaging films, functional agricultural films, industrial protective films, and more, making it an ideal choice for enhancing product added value and expanding into high-end markets.
1.Extrusion System: Three extruders (screw configurations can be adjusted according to raw material characteristics). 
2. Co-Extrusion System: The core is a multi-layer co-extrusion rotary die, ensuring uniform interlayer bonding and consistent thickness. 
3. Blown Film and Cooling System: Includes die head, cooling air ring, blown film frame, etc. 
4. Traction and Winding System: Includes herringbone boards, traction rollers, and winding machines to achieve smooth film traction and tension control. 
5. Electrical Control System: Uses PLC and touch screen to achieve precise control of process parameters such as temperature, speed, and tension. 

Main Product Features ：
1.Strong Functionality: Can produce films with high oxygen barrier, moisture resistance, fragrance preservation, and oil resistance.
2.Flexible Structural Design: Layer thickness ratios can be freely adjusted according to requirements (e.g., A/B/C structure). 
3.High Production Efficiency: One-step forming, high process integration, and stable film quality.
4.Good Economic Benefits: Optimized raw material structure, making it an ideal equipment for cost reduction and efficiency improvement. ...
