SJ-FMH High-Speed Dual-Extruder Extrusion Coating and Lamination Machine use PE, PP or EVA as raw material, to be extrusion coating or laminating with paper, which is suitable for producing multi-layer composite material such as liquid packaging paper, paper-cup paper, adhesive paper, etc.

The machine adopts automatic micro-computer control for the whole technology flow from substrate unwinding, lamination to winding, equipped with PLC and touch-screen color monitor, integrated with HMI developed by ourselves, to achieve operation and control of the entire machine. The extruders adopt automatic temperature control, pneumatic feeding, stepless speed control and strainer changers. The dies are equipped with high-precision bidirectional handwheels for adjusting the dies. Chill rolls of the laminators adopt high-precision forced water cooling structure. The unwinder and the winder adopt dual-station automatic turreting, automatic splicing and automatic tension control, to achieve jumbo roll changing at high speed without shutdown. Equipped with a hydraulic roll loading and unloading device, an industrial chiller, a corona treater, a length counter, an adjustable edge-trimming device, and an edge-strip blowing device. As per the customers' requirements, a second substrate unwinder (for aluminum foil or color film) can be added.

According to the products' structure, the machine can utilize the co-extrusion technology, cooperating with a multilayer (two-layer or three-layer) extrusion system, to produce multi-layer composite packaging material.

The lamination speed can be up to 350m/min, as per the customers' requirements.
