摘　　要：高性能多层共挤包装膜的制备方法主要有流延法和吹塑法,与多层共挤流延工艺相比,多层共挤吹塑工艺具有生产效率高,设备成本低,材料损耗低等优点,更加适合多配方、小批量的柔性生产。常规3、5、7层包装膜的多层共挤吹塑技术已相对成熟,但九层以上的高性能包装膜共挤吹塑技术和装备市场仍处于长期被几家国外公司垄断的局面。金明公司十四五期间研制了九层上吹和十一层下吹先进装备并产业化,研发了高兼容、短流程的九层、11层共挤、三风口高效冷却风环、水气分离式真空水环等关键技术。The processing way of high-performance multi-layer co-extrusion blown film mainly include casting processing way and blow processing way.Comparing with the multi-layer co-extrusion casting process way,the blow processing way has the advantages of high production efficiency,low equipment cost and low production material loss,which is more suitable for flexible production of multiple formulations and small batches.The multi-layer co-extrusion blow film technology of conventional three-layer,five-layer,and seven-layer co-extrusion packaging film is relatively mature,but the high-performance packaging film co-extrusion blow film technology and equipment market with more than nine layers co-extrusion are still monopolized by several overseas manufacturers for a long time.During the 14th Five-Year Plan,Jinming Company had developed and industrialized advanced machine for nine-layer co-extrusionand eleven-layer co-extrusion water quench blown film line.It has developed key technologies such as high-compatibility and short-process nine-layer and eleven-layer co-extrusion,as well as high-efficiency cooling air rings with three air outlets,and vacuum water rings with water-gas separation.
