共挤出复合加生产线主要由—多料道结构的复合模头和数台并联螺杆挤出机及其压力牵伸轴辊等组成。该生产线主要特征是,以容融共挤出复合方式,将数种不同物性的热塑性树脂基材一次加工成具有优良综合性能的层状复合包装材料。这种包装材料适用于液态或膏状物质的软包装,如牛奶制品、果汁饮料等。该加工流程的优点是,生产线较短、热电消耗减少、产品生产周期缩短、活性粘合层节省等。
Coextrusion compound with the production line mainly by - multi-channel structure of the composite die and several parallel screw extruder and its pressure roller axis and other components. The main features of the production line are that the thermoplastic resin base material with several different physical properties is processed into a laminated composite packaging material with excellent comprehensive performance in one time by a compatibilizing and extruding method. This packaging material is suitable for flexible packaging of liquid or pasty substances, such as milk products, fruit juice drinks and the like. The advantage of this process is that the production line is shorter, the thermoelectric consumption is reduced, the production cycle is shortened, and the active adhesive layer is saved.
