SJCO Series 55/75-75/75
The innovative double-layer co-extrusion film blowing machines and comprehensive film blowing series are marvels of efficiency and sustainability. Utilizing two extruders, they craft AB two-layer or three-layer high-strength films. Notably, the film blowing machine features a dual-host system that facilitates tri-layer extrusion: one handles the inner and outer protective layers, while the other focuses on the inner filling layer. This strategic design not only reduces costs but also enhances energy efficiency and lowers consumption. Furthermore, the ability to incorporate recycled materials and calcium carbonate into the filling layer-potentially constituting over 80% of total output-substantially slashes raw material costs, thereby amplifying your market competitiveness.
