用途
用于吹制低密度聚乙烯(LDPE)、高密度聚乙烯(HDPE)和线性低密度聚乙烯(LLDPE)等塑料复合膜。广泛应用于液体包装、印刷基材、出口产品包装、工业品包装等。
特点:
1、两层共挤复合膜可延长液体包装保鲜期。
2、挤出机的机筒、螺杆均采用优质合金钢经精密加工和氮化处理，使其硬度达到最佳值，经久耐用。
3、辅机设平台式工作台，使操作方便并配制定泡圈。
4、卷取装置：双收双剖，其动力采用力矩电机，可保持适宜的张力，收卷整齐，换卷方便。
主要技术参数
use
Used for blowing plastic composite films such as low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE). Widely used in liquid packaging, printing substrates, export product packaging, industrial product packaging, etc.
Features:
1. Two-layer co-extruded composite film can extend the shelf life of liquid packaging. 2. The barrel and screw of the extruder are made of high-quality alloy steel through precision processing and nitriding treatment to make the hardness reach the best value and durable. 3. The auxiliary machine is equipped with a platform-type working table, which is convenient for operation and is equipped with a bubble ring. 4. Winding device: double-winding and double-cutting, its power adopts torque motor, which can maintain proper tension, tidy winding and easy roll changing.
