3 Layers Blown Film Extrusion

Three layers blown film extrusion
The adoption of a three layers blown film extrusion system, which includes three extruders, motors, gearboxes, and inverters, enables the production of a three-layer film, such as ABC three-layer co-extrusion, using a plastic film blowing apparatus. This setup is proficient in manufacturing films from HDPE, LLDPE, and LDPE materials. By utilizing multi-layer co-extrusion technology, the system greatly enhances the strength and durability of the resulting film. The design employs a single main extruder to provide material for both the inner and outer layers, thereby minimizing the necessity for additional extruders, leading to improved energy efficiency and reduced consumption levels.

In summary, our three layers blown film machinery is meticulously engineered to optimize production efficiency, elevate product quality, and ensure cost-effective operations, making it a valuable investment for businesses in the film production sector.
