Product Description:
The Riqiang seven-layer co-extrusion blown film machine features seven fully independent screw extrusion systems. Layers A through G can be independently proportioned, temperature-controlled, and regulated, enabling precise arrangement and integrated forming of barrier layers, tie layers, strength layers, and heat-sealing layers. The machine is compatible with a wide range of materials including LDPE, HDPE, LLDPE, mLLDPE, EVA, PA nylon, EVOH high-barrier resin, and adhesive resins, producing ultra-high-performance barrier films in both symmetrical and asymmetrical structures. Equipped with a seven-layer stacking die head, each layer can be independently heated and contains thermal insulation media, facilitating the blowing of plastic films with large temperature differences; the uniform flow channel distribution ensures fluid stability and film thickness uniformity. Combined with the IBC internal bubble cooling system and a 360° horizontal rotary haul-off unit, the machine delivers uniform film thickness and flat winding, meeting the stringent requirements of high-precision, high-speed printing. Riqiang Machinery includes the seven-layer co-extrusion blown film machine in its high-end functional film extrusion equipment product line, targeting packaging applications with extremely high requirements for barrier properties, strength, and printability
