High-Efficiency Single-screw Film Blower


Key Features Of This Film Blower


High-Efficiency Melting & Plasticization System

The mSingle-screw Film Blower adopts a single-screw structure with a length-diameter ratio of up to 32:1, paired with a screw made of high-quality 38CrMoALA+ALLOY and a 38Cr barrel. This design enables efficient heating, compression, and melting of plastic granules, transforming them into homogeneous melt for consistent extrusion. It excels in processing PE and PP materials, ensuring thorough plasticization without impurities.


Intelligent Temperature Control Technology

Equipped with an advanced intelligent temperature control system, the machine maintains precise temperature regulation across multiple heating zones. Ceramic heaters provide stable heat distribution, eliminating temperature fluctuations that affect film quality. This feature guarantees the uniformity of film thickness, a critical factor for meeting industry standards.


Flexible Winding & Slitting Mechanism

Supporting both center and surface winding modes, the single-screw film blowing machine offers in-line slitting functionality. It can produce single or multi-roll outputs of various widths, adapting to customized requirements for film dimensions. The torque motor-driven winding system ensures smooth, tight rolls without film deformation.


User-Friendly Operation & Low Maintenance

Designed with simplicity in mind, the High-Efficiency Single-screw Film Blower features an intuitive control panel that allows new users to master operations quickly after basic training. Vulnerable parts are easily accessible and replaceable, reducing downtime and maintenance costs. Its robust construction ensures long-term durability even under continuous operation.

Application Scenarios


Daily-Use Plastic Films

Ideal for producing plastic wrap, garbage bags, and express bags. The Film Blower’s low thickness tolerance (0.008-0.2mm) ensures these lightweight films are cost-effective while meeting basic strength requirements. SMEs can cater to the huge demand for daily-use packaging with this equipment.


Commercial Shopping Bags

Suitable for manufacturing thin, durable shopping bags for retail stores and supermarkets. The uniform film thickness ensures consistent load-bearing capacity, and the flexible slitting function allows customization of bag widths.


Agricultural Films

Produces ordinary agricultural films for covering crops, protecting them from harsh weather. The machine’s stable extrusion ensures the film’s thickness uniformity, enhancing its durability and light transmission.


Industrial Packaging Films

Can process thicker films (up to 0.15mm) for wrapping industrial parts or goods. The high-quality melt ensures the film’s tear resistance and puncture resistance, meeting industrial packaging standards.
