SJCO Series 55/75-75/75
Our Double-layer Co-extrusion Film Blowing Machine series is meticulously engineered to deliver exceptional performance and superior film quality. Utilizing two advanced extruders, it produces robust AB two-layer or innovative three-layer high-strength films. This remarkable film blowing machine features dual hosts that supply three-layer extrusion: one dedicated to the inner and outer coating layers, and the other providing the crucial inner filling layer. This intelligent design significantly reduces production costs, enhances energy efficiency, and minimizes consumption. Furthermore, the incorporation of recycled materials and calcium carbonate into the internal filling layer-which constitutes over 80% of the total output-dramatically lowers raw material costs, empowering our valued customers with a formidable competitive edge in the marketplace.
