Main features: Structure of produced product: Single-side four-layer extrusion lamination at one time, main base material/extrusion layer A, B/interlayer base material. High performance, low cost. Changing plastics/resins in extrusion layer A or/and B can produce many kinds of multi-layer(X) extruded packaging film; Extruder: Φ 70mm/Φ 90mm, Φ 90mm/Φ 90mm, 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 divider (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 reeling and unreeling structure (only one in our country) with advanced international level (Italian technique).
