New functional film three-layer co extrusion composite casting experimental line
The three-layer co extrusion casting blown film composite equipment can select the number of laboratory small extruders according to the product structure, and combine with the three-layer casting die to form a laboratory small multi-layer co extrusion casting film machine to prepare multi-layer co extrusion films. This unit can achieve plastic plasticization, quantitative extrusion, and casting molding through three independent small single screw extruders, realizing multi-layer co extrusion casting and multi-layer film out of mold composite, thereby preparing multi-layer co extrusion composite films with different structures and functions In addition, the device can test the extrusion and casting performance of film materials by adjusting the formula and process conditions of plastics, which can be used for formula research and development of film materials. It can also prepare the optimal extrusion and casting process parameters for certain materials and structures of film materials, which can be used to guide the setting and adjustment of actual production processes and control the quality of films.
