PLA Degradable Sheet Plastic Sheet Extrusion Machine Food Grade For Water Cup
PLA degradable sheet production line Food Grade Degradable Disposable Water Cup
The screw adopts the gradient type single screw design, which is specially designed for the polylactic acid and corn starch melting. At the same time, it can be opened and vented according to the speciality of the material. The three-roll calendering is formed, and the temperature of the roller can be adjusted by the mold temperature machine. No paste, the product molding surface has good color, good toughness, the thickness is measured by the dial gauge, and the winding is automatically tensioned.
Process principle: PLA corn starch material → single screw extruder: raw material melt plasticization → quick change filter → extrusion die forming extrusion → vertical three roll calender → cooling setting device → trimming mechanism → traction Transfer → automatic tension winding
