The Twin Head Blown Film Production Line is a high-performance industrial extrusion solution engineered to maximize productivity by producing two independent plastic film rolls from a single screw cylinder. By integrating dual die heads, dual upper tractions, and dual winders into one reinforced frame, this system is specifically optimized for the high-efficiency manufacture of small-width LDPE and HDPE films, making it the premier choice for T-shirt bags, rolling bags, and commercial shopping bags.
Designed for maximum versatility and resource optimization, this dual-head system allows manufacturers to run different film widths, thicknesses, or material grades—such as food-grade and industrial-grade PE—simultaneously. By sharing core power systems and cooling infrastructure, the production line significantly reduces energy consumption and workshop footprint without compromising on precision, film quality, or industrial-grade durability.

Cylinders and screws are crafted from high-quality alloy steel with nitration for maximum hardness and corrosion resistance.
Double the output per cycle by producing two film rolls simultaneously, drastically reducing bulk order lead times.
Shared power systems and cooling pumps lower initial acquisition costs and overall energy consumption.
Integrated frame design saves over 50% of workshop floor space compared to two separate single-head machines.
Ability to produce different widths, thicknesses, or material grades on each head at the same time.
Independent head operation allows for maintenance on one side while the other continues production.
Seamlessly switch between HDPE, LDPE, LLDPE, and recycled resins to meet evolving market demands.
Easily adjustable parameters for film thickness and width to ensure strict adherence to specifications.
Independent head design facilitates scheduled maintenance without stopping total plant production.
Reduced carbon footprint through optimized power supply and combined cooling water pump systems.
Faster turnaround for small-width orders like T-shirt and rolling bags via dual-output capability.
Tailored screw L/D ratios and die diameters based on resin characteristics and output goals.
| Comparison Metric | 2x Single Head Lines | 1x Twin Head Line |
|---|---|---|
| Workshop Space | 100% Footprint | ~50% Footprint |
| Energy Consumption | High (2 Separate Motors) | Optimized (Shared Systems) |
| Labor Cost | Higher (2 Operators) | Lower (1 Operator) |
| Production Speed | Standard | Increased (Dual Output) |
| Initial Investment | Higher Acquisition Cost | Lower Integrated Cost |
It is primarily used for producing small-width plastic films such as T-shirt bags, rolling bags, and various types of shopping bags using HDPE and LDPE materials.
Yes, the twin-head design allows you to produce films of different widths, thicknesses, or even different material grades (e.g., food-grade and industrial-grade) simultaneously.
It reduces costs by sharing power systems and cooling pumps, requiring less workshop area, and decreasing the amount of labor needed to manage the output.
The machine supports a wide range of materials including HDPE, MDPE, LDPE, LLDPE, CACO3, and various recycled plastic resins.
Each head can operate independently. This means one head can undergo maintenance or a material change while the other continues to produce, minimizing downtime.
Absolutely. Parameters such as die size, screw diameter, and motor power can be customized based on your required film width, thickness, and raw material characteristics.
