Main features: Structure of produced product: Five-layer extrusion lamination at one time (including paper layer, plastic layer, aluminum layer), extrusion layer A/main base material/ extrusion layer B, C/interlayer base material. High performance, low cost. Changing plastics/resins in extrusion layer A, B or C can produce many kinds of multi-layer extruded packaging film; Extruder: Φ 80mm, Φ 90mm, Φ 100mm, high-performance extruder(Japanese technique); Die head: Double-layer co-extrusion device, which is composed of the high-precision full-seal original imported die head(made in Taiwan, Japan or Italy) and the high-precision co-extrusion feedblock (made in Taiwan, Japan or Italy); Control type: High-precision PLC(Siemens, Mitsubishi) programmable control, HMI (Siemens, Hitech) dialog, whole integrative running; Transducer: Japanese ANCHUAN digital vector control transducer; Tension control: Full automatic constant tension control for reeling, unreeling and every tension point; Reeling and unreeling machine: Adopt the round-plate type rewinding and unwinding structure(only one in our country) with advanced international level (Italian technique).
