核心特点 / Key Features

中文：

• 三层独立控制：A、B、C三组螺杆完全独立驱动，每层可单独加工不同原料，实现外层PE热封、中层EVOH/PA阻隔、内层功能料的三层异材复合
• 高精度温控：±1℃温控精度，原料塑化均匀，薄膜厚薄偏差控制优异，有效避免晶点与碳化
• CFD优化模头：流体仿真优化设计，三层料流均衡稳定，出膜均匀、无横纹、无晶点
• 双结构可选：风冷上吹 / 水冷下吹两种结构定制，适配不同产品需求
• IBC内冷系统（选配）：超声波控制膜泡尺寸，提升薄膜透明度与产量
• 旋转牵引系统：360°水平旋转或摆动牵引，薄膜收卷平整，减少印刷套印偏差
• 原料适应性广：适配LDPE、HDPE、LLDPE、PA尼龙、EVOH、EVA、生物降解料、色母填充料等
• 良品率高：出膜均匀稳定，良品率稳定在98%以上

English:

• Three-layer independent control: Three sets of screws are fully independently driven, each layer capable of processing different materials — outer PE heat-sealing, middle EVOH/PA barrier, inner functional layer — for three-layer dissimilar material composite
• High-precision temperature control: ±1℃ temperature accuracy ensures uniform plasticization and excellent thickness deviation control, effectively preventing gel spots and carbonization
• CFD-optimized die head: Fluid simulation-optimized design ensures balanced and stable flow of all three layers, producing uniform film free of horizontal streaks and gel spots
• Dual structure options: Air-cooled upward blowing / water-cooled downward blowing configurations available to suit different product requirements
• IBC internal bubble cooling (optional): Ultrasonic bubble size control improves film transparency and output
• Rotary haul-off system: 360° horizontal rotation or oscillating haul-off ensures flat winding and reduces registration deviation in printing
• Wide material compatibility: Compatible with LDPE, HDPE, LLDPE, PA nylon, EVOH, EVA, biodegradable materials, color masterbatch and filler masterbatch
• High yield rate: Uniform and stable film output with a yield rate consistently above 98%
