The development history of stretch film machine

      Stretch film machine can be divided into two phases of development, a stage is the early stage and there's a bear.
      Is beginning in the ninety s, from Germany, Japan, Austria and other countries introduced multi-layer co-extrusion flow film production process flow. Our country introduced the device on the capacity range is 500 to 6500 t/a. And the part at the same time of introducing the domestic production manufacturers, independent research and development a domestic unique stretch film production line. But while the domestic research and development equipment, but this kind of equipment only small-scale production, the quantity of its production or imports of machinery and equipment and compare.
      After they entered the mature stage, during this period in the 21st century, domestic stretch film machine has made great progress on production performance, in international competitiveness are also gradually expanded, part of the technical indicators have reached the foreign production standard of the same kind of stretch film, stretch film machine is just come into the mature stage of rapid development.
