Product Description:
The Riqiang single-screw blown film machine adopts a single-screw extrusion structure, purpose-designed for blowing HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene) plastic films. The screw and barrel are made of 38CRMOALA alloy steel, subjected to nitriding treatment and precision machining, offering high hardness, strong corrosion resistance, and long service life. The die head features a spiral mandrel structure with hard chrome plating, ensuring uniform melt extrusion and smooth film surface; the air-cooling device adopts a labyrinth-type structure for even air distribution. The machine is equipped with a horizontal reciprocating oscillating haul-off system that replaces the traditional rotating die head structure, effectively eliminating material leakage, sealing difficulties, and maintenance challenges, overcoming quality defects such as uneven roll ends and loose/tight edges, and ensuring excellent film flatness. The machine can process HDPE, LDPE, LLDPE, and other polyethylene materials, suitable for film production in food packaging, garment & textile, daily necessities, and industrial packaging applications — a practical basic machine for small and medium-sized film blowing enterprises
