Three layers blown film extrusion
The implementation of a three-layer blown film extrusion system, comprised of three extruders, motors, gearboxes, and inverters to create a three-layer film like the ABC three-layer co-extrusion blown film via a plastic film blowing machine, provides significant advantages. This setup excels in producing HDPE, LLDPE, and LDPE films. Utilizing multi-layer co-extrusion technology enhances the film’s strength. By using a single primary extruder for both outer and inner layers, the need for extra extruders is reduced, promoting energy efficiency and lower consumption rates.
Essentially, our meticulously designed three-layer blown film equipment is engineered to optimize production processes, elevate product quality, and ensure cost-effective operations, making it a valuable investment for businesses in the film production industry.
