Twin Head Blown Film Production Line China Factory and Leading Suppliers

Maximize output with our Twin Head Blown Film Production Line. As professional China suppliers and a top-tier factory, we deliver high-efficiency extrusion systems for HDPE and LDPE films used in food and textile packaging.

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.

Key Advantages

Premium Metallurgy

Cylinders and screws are crafted from high-quality alloy steel with nitration for maximum hardness and corrosion resistance.

Increased Capacity

Double the output per cycle by producing two film rolls simultaneously, drastically reducing bulk order lead times.

Resource Efficiency

Shared power systems and cooling pumps lower initial acquisition costs and overall energy consumption.

Space Optimization

Integrated frame design saves over 50% of workshop floor space compared to two separate single-head machines.

Flexible Adaptability

Ability to produce different widths, thicknesses, or material grades on each head at the same time.

Minimized Downtime

Independent head operation allows for maintenance on one side while the other continues production.

Frequently Asked Questions

Q: What are the primary applications of the Twin Head Blown Film Production Line?

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.

Q: Can I produce two different types of film at the same time?

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.

Q: How does the twin-head system save on operational costs?

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.

Q: What materials are compatible with this extrusion machine?

The machine supports a wide range of materials including HDPE, MDPE, LDPE, LLDPE, CACO3, and various recycled plastic resins.

Q: What happens if one die head requires maintenance?

Each head can operate independently. This means one head can undergo maintenance or a material change while the other continues to produce, minimizing downtime.

Q: Can the machine specifications be customized for my specific product?

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.
