本生产线以LLDPE(线性低密度聚乙烯)为主要原料，通过挤出而生产出具有自粘’陛的单面粘或双面粘二层或三层共挤拉伸缠绕膜，生产的共挤缠绕膜比单层缠绕膜具有更高的拉伸强度、抗穿刺能力及耐冲击性，同时具有良好的回缩记忆及自粘性。 设备特点： 1特殊设计的螺杆及静态混合器，确保塑化良好，色泽均匀，挤出量高。 2模头材质采用进口模具钢，经过精加工及热理，保证模头长期使用不变形，出料更均匀。 3冷却钢辊内部采用双向回路设计，内置螺旋流道，保证辊面温度均匀。 4全线采用PLC控制，自动换卷，隐蔽式自动切刀，操作安全又方便，确保了收卷的质量。 This production line uses LLDPE as main raw material，and adopts several different kinds of resin It can produce two—layer or three．1ayer stretch film which has the property of autohension .The coextrusion stretch film has better tensile strength．Anti puncture capability and shock resistance than monolayer film, And in the meantime，it has good retraction memory and autohension.It also has excellent transparency and extensibility. Machine features： 1.Special designed screw and static mixer can ensure good plasticizing，uniform colour and lustre and high capacity. 2.The material of die head adopts imported die steel and processes with finish machining，so it can avoid the deformation of die head. 3.The internal of cooling steel roller adopts bidirection return circuit design，inlaying spiral passageway，it can ensure the uniform temperature of the roller surface. 4.This production line adopts PLC control，automatic changing reel and concealed automatic cutter，it ls safe and convenient. 主要技术参数Main technical parameters
