An ABA 2-layer blown film plant is an advanced, cost-effective extrusion line that produces a 3-layer film structure (Layer A, Layer B, and Layer A) using only two extruders. By sandwiching a cheaper core layer (B) between two premium outer layers (A), it maximizes film strength while significantly lowering material costs.

Key Features and Specification's

An ABA setup offers a competitive advantage by allowing manufacturers to use heavy amounts of recycled plastics, fillers, cheaper resins in the core.

Extruder Setup: Two independent extruders (one larger for the core, and one smaller for the two outer layers) feed into a single co-extrusion die head.

Screw & Barrel: Usually equipped with barrier or Maddock mixing screws to ensure uniform melting and blending of additives.

Die Head: A specialized ABA co-extrusion die evenly splits the resin from the smaller extruder to form the inner and outer A-layers.

Layflat Film Width: Typically ranges from 500 mm to 2500 mm depending on the extruder size.

Output Capacity: Common production ranges vary from 40 kg/hr to 200 kg/hr, providing excellent power-to-yield efficiency.

Control System: Often features microcomputer/PLC interfaces with HMI touchscreens for temperature control, bubble stability, and online thickness monitoring.
