How it works
How it works,
step by step
Screw Extrusion
Raw polymer pellets compatible with PP, PE, or CPE are fed into twin 65mm screws driven by a 22 kW main motor. Mechanical shear and barrel heaters convert the solid resin into a homogeneous melt before it advances to the die assembly. This continuous feeding stage establishes the baseline throughput for the entire line.
Rotary Head Forming
The molten polymer enters a double-layer rotary head where two independent melt streams are combined into a single annular flow. Internal land length adjustments ensure uniform pressure distribution across the die gap. This configuration eliminates weld lines and prepares the melt for stable inflation.
Inflation and Cooling
Controlled air pressure expands the extruded tube into a vertical bubble while a cooling ring removes excess heat from the outer surface. The operator sets the final dimensions using the draw-down ratio, targeting film widths between 200 and 1000 mm and individual layer thicknesses from 0.01 to 0.15 mm. Consistent cooling stabilizes the polymer crystallinity before downstream handling.
Traction and Winding
Heated nip rollers engage the cooled bubble and pull it downward at regulated traction speeds to flatten it into a dual-layer film web. The system sustains a maximum output of 100 kg/h while maintaining constant tension across the material path. The flattened film is then directed to a winding station for final collection and slitting.

Frequently asked
questions
How much does this machine cost?
Factory-direct pricing depends on your configuration — width, output, layer or color count and automation level. Send us your target specs and we confirm an exact price within one business day.
What affects the price of this machine?
The main price drivers are machine size and output, number of layers or colors, servo versus stepper drives, automation features, certifications (CE/EAC), voltage adaptation, and shipping and installation terms.
What film width and thickness can this machine produce?
The line handles the width and thickness range shown in the spec sheet — typically 500–2500 mm film width and 0.01–0.12 mm thickness, depending on the model. The exact range for your configuration is confirmed in the proposal.
What materials does it process?
Standard blown film lines process LDPE, LLDPE, HDPE, MDPE and EVA; multi-layer models also run PA and EVOH barrier layers for high-barrier packaging film.
How long is delivery?
Typical delivery is 15–30 days from order confirmation, depending on the configuration and current production schedule. We confirm the exact lead time in the quotation.
Is the machine CE certified?
Yes. Our machinery is assessed to the Low Voltage Directive 2014/35/EU, Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. The certificate of conformity is provided with the machine.
Can the line be customized?
Yes — film width, output, layer structure, die diameter and automation level are all configurable. Tell us your material and daily output target and we will size the line around it.
Do you provide installation and training?
Yes. Our engineers supervise installation and commissioning on site, run the first production trials and train your operators — on-site or remotely.
