Multi layer co extrusion (top blown rotary traction) packaging filmFilm Blowing MachineFeatures:
Traction level ± 180 degree swinging rotation, scientifically reasonable structure, energy-saving and easy maintenance. Replaced the rotation of the mold head, simplified the structure of the mold head, and completely solved a series of problems such as long flow channels, difficult melt sealing, easy material leakage, uneven heating, difficult maintenance, and large film thickness tolerances of the rotating mold head. Simplified the difficulty of material selection and production process control for multi-layer co extruded products. It can increase the internal cooling system of the membrane bubble, which can produce thin film products with higher transparency and better physical properties. The thin films produced using this technology have extraordinary flatness and precise film roll fixation, meeting the requirements of high-precision and high-speed printing.
