Blown film machine

Jinming multi-layer co-extrusion bottom blowing water-cooled plastic film blowing unit is manufactured with domestic and international high-tech patented technology. It can produce barrier films with symmetrical and asymmetric structures with good barrier properties, high mechanical strength, and good transparency. The barrier layer can reach more than three layers. It is used for food, agricultural and sideline products, medical treatment (oral and injection drugs, plasma, equipment), chemical industry , Daily necessities and military supplies provide high barrier, high performance functional plastic packaging materials.
The whole machine adopts a modular design idea. According to different film formulations and requirements, you can choose automatic film thickness adjustment die, two-stage cooling water ring, vacuum sizing water ring, rotary traction system, etc.
Down-blowing water-cooled production of high barrier film has the following characteristics:
◆ Amorphous film structure, convenient for MDO processing;
◆ Better transparency/gloss (even better than casting)
◆ Better mechanical strength, including stiffness, puncture resistance and impact of falling mark;
◆ The film is soft and has good hot-line processing performance;
◆ Processing asymmetric high barrier film can control the direction of winding;

The modular design concept of the whole machine includes:
◆ Interlayer proportional control system, which is convenient for users to process different raw materials, and saves the amount of expensive resin under the premise of ensuring barrier performance;
◆ Fieldbus computer centralized control system, through the digital communication network to control the temperature, speed, pressure, wind speed, traction, tension, linear speed and other systems of the whole machine, and display and monitor the temperature, pressure, current, voltage, tension, Speed, length and other parameters, and have functions such as automatic alarm and self-diagnosis.
