Blown Film Machine SH-SF32/SH-SF40

The SH-SF32 and SH-SF40 models are advanced blown-film extrusion machines designed to deliver high-quality polyethylene (PE) film, incorporating both HDPE/LLDPE/LDPE and recyclable materials. With screw diameters corresponding to the “32” and “40” designations (mm), these machines are ideal for medium-capacity film production lines – such as bags, liners, sleeves, and packaging film. Built for continuous operation, excellent film uniformity and cost-efficient output, they are well suited for manufacturers looking for a reliable, mid-range blown-film line.

Details

• Both machines feature advanced extruder screws — 32 mm and 40 mm respectively — paired with efficient die heads and air rings that guarantee consistent bubble formation and uniform cooling. The SH-SF32 is suited for lighter production requirements, while the SH-SF40 offers higher output capacity, making it a flexible choice for businesses with growing production demands.

• Constructed from high-grade alloy steel with nitrided treatment, the SH-SF series ensures long-term durability and minimal maintenance. The system is equipped with intelligent temperature control, inverter-driven motors, and precision take-up units to optimize energy consumption and film quality. Its design also emphasizes user safety and easy operation, with quick-change components and a clear control interface.

• Compatible with LDPE, LLDPE, and HDPE, these machines deliver consistent performance whether using virgin or recycled materials. The SH-SF32/40 series represents a perfect balance between efficiency, reliability, and cost-effectiveness — making it an excellent choice for manufacturers seeking dependable film extrusion technology with stable output and long service life.
