TECHNICAL PARAMETERS：

The Riqiang ABC three-layer co-extrusion food packaging film blown film machine features three fully independent screw extrusion systems. Layers A, B, and C can be independently proportioned, temperature-controlled, and pressure-regulated, enabling three-layer dissimilar material composite forming in a single pass — outer functional layer, middle barrier layer, and inner heat-sealing layer. The machine processes a wide range of materials including LDPE, HDPE, LLDPE, PA nylon, EVOH high-barrier resin, EVA, and fully biodegradable materials, meeting the comprehensive requirements of food packaging for barrier properties, heat-sealing performance, and printability. Equipped with a ±1℃ high-precision temperature control system, the finished film maintains an oxygen transmission rate consistently below 15, fully satisfying high-standard packaging requirements for food and medical applications. The machine supports both air-cooled upward blowing and water-cooled downward blowing configurations, and adopts a CFD fluid simulation-optimized die head to ensure balanced and stable flow of all three layers, producing uniform film free of horizontal streaks and gel spots, with a yield rate consistently above 98%
