Vertical Traction Rotary Blown Film Machine

High speed mono-layer vertical rotary film blowing machine is an efficient solution for producing high-quality blown films. It can make plastic films with a width of 200–1000 mm and has a height similar to a conventional film blowing machine.

  Application

  The high-speed mono-layer vertical rotary film blowing machine is designed with a main force-feeding system and a vertical rotary traction unit. This configuration helps deliver more even film thickness and neater winding. The machine also effectively addresses common issues with rotary die heads, including oil and granule leakage. It produces superior film quality and is ideal for manufacturing shopping bag films (HDPE/LDPE are supported; T-shirt bag film can also be produced).
• 
  Extrusion System

  The extruder is typically a single-screw extruder. The screw is typically manufactured from nitrided 38CrMoAlA steel. This nitriding treatment provides high surface hardness and improved wear resistance, supporting efficient plasticization of PE materials. The barrel is equipped with zoned heating coils for accurate temperature control, ensuring a stable transition from solid to molten state. A variable frequency motor allows the extrusion rate to be precisely controlled by adjusting the speed, enabling the machine to meet production requirements for films of varying thicknesses.

  Advantage

  One of the key features of the machine is its vertical traction system, which provides a more stable and reliable film blowing process. The vertical rotary traction device offers greater flexibility in film thickness quality, allowing configuration to match specific production requirements. The machine is also equipped with an advanced automatic discharge roll function, enabling automatic film roll discharge and reducing labor requirements to a certain extent. The high-speed mono-layer vertical rotary film blowing machine is energy-efficient, helps reduce operating costs, and offers a cost-effective solution for your production needs.
