Polytevo Series Film Blowing Machine
Product Detail
Polytevo Series Film Blowing Machine (ACS-7008FB) is a PLC-programmable laboratory film blowing machine with a 20 mm single-screw extruder (L/D 28:1, RT to 380°C), a Ø25 mm annular die and a maximum folded film width of 80 mm, used to evaluate the film-blowing feasibility of polymers and degradable materials.
In extrusion film blowing, a plastic melt is continuously extruded through a die, expanded by compressed air and cooled via a cooling ring, and variable-frequency traction produces double-fold plastic film. The ACS-7008FB is primarily used to evaluate the film-blowing feasibility of polymers and degradable materials, to assess the melt gel content within materials, and to examine the dispersibility of colored dispersions, controlled mixtures and extrudates.

Where it fits
Frequently asked questions
What does the ACS-7008FB do?
It produces double-fold blown film from a continuously extruded melt that is expanded by compressed air, cooled via a cooling ring and drawn by variable-frequency traction. It is used to evaluate the film-blowing feasibility of polymers and degradable materials and to assess melt gel content and dispersibility.
What are the extruder specifications?
20 mm screw, L/D 28:1, compression ratio 2.3:1, screw speed 0.1–120 rpm, output approximately 5 kg/h and a temperature range of RT to 380°C.
What film size can it make?
The annular die opening is Ø25 mm and the maximum folded film width is 80 mm.
How is the machine controlled?
By a PLC with a 10-inch color touch screen and HMI system that shows zone temperatures, screw speed and traction speed; traction and winding have independent button controls.
What power supply does it need?
The main unit uses 3-phase AC 380 V ±10%, 5.5 kW; the auxiliary equipment uses AC 220 V ±10%, 1.17 kW. Compressed air of 0–0.8 MPa is used for inflation.
