An ABA Three Layer Die is a specialized die head used in blown film extrusion lines to produce three-layer film structures with two outer layers (A) and one inner core layer (B). This configuration allows manufacturers to combine different materials or reprocessed blends, improving film strength, cost-efficiency, and processability.

The ABA structure is an alternative to traditional ABC multilayer systems, offering similar benefits with fewer extruders (only 2 required instead of 3).
