Two layer co extrusion fully automatic roll changing blown film machine
2026/4/28

Characteristics of double-layer co extrusion blown film machine:
The dual extrusion system works together and is equipped with two independent extruders, which can control the plasticization process of different materials separately. Each extruder can independently adjust the temperature to adapt to materials with different melting points,
Such as PA/PE co extrusion, speed, precise control of the thickness ratio of each layer, and customized screw design based on material characteristics. Special co extrusion die design: multi-layer channel composite structure, with independent channels inside the die,
Ensure that the two layers of melt do not interfere with each other before composite, and avoid interlayer turbulence. Composite interface control technology, rotating die head automatically eliminates thickness deviation, fine tuning die lip manually/automatically adjusts layer thickness uniformity,
Wide material compatibility: Supports combinations of PE/PP/PA//EVA/degradable materials, precise control of layer thickness: By independently adjusting the output of two extruders, the layer thickness ratio can be freely set, such as 80/20, 50/50, etc,

Optional online thickness gauge+automatic feedback system, real-time monitoring and adjustment of thickness of each layer.
