三层共挤吹膜机原理

特点/CHARACTERISTICS
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、螺杆均采用合金钢经精密加工和氮化处理，使其硬度达到佳值，。
3、辅机设平台式工作台，使操作方便并配制泡圈。
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。
1、Double-layer co-extrusion laminated film can prolong the length for preservation of liquid package
2、The cylinder and the screw stem of the extruder are made of high quality alloy steel with optimum hardness and durable service after precision finishing and nitrogen treatment.
3、The auxiliary machine has a platform working table for making operation easy and is equipped with bubble stabilizing ring.
4、Double-rolling and double-cutting coiling unit adopts torque motor to keep proper tensions and make rolling even and roll changing
