What ABA means
ABA repeats the A formulation on both skins and places B in the core, fitting structures where both surfaces serve similar roles.
What ABC means
ABC uses three extruders so A, B and C can differ, useful when the two surfaces and core need distinct functions.
| Factor | Single | ABA | ABC |
|---|---|---|---|
| Structure | A | A/B/A | A/B/C |
| Extruders | 1 | 2 | 3 |
| Material flexibility | One formula | Matching skins, separate core | Three differentiated layers |
| Complexity | Low | Medium | Higher |
| Investment logic | Straightforward products | Skin/core logic | Distinct A/B/C roles |
Production complexity
ABC adds formulation freedom but also material handling, setup and changeover demands. Team capability and quality control matter.
Decision criteria
Use the required film structure, volume per SKU, formulation-change frequency and total production economics as decision criteria.
Frequently Asked Questions
Does this guide guarantee machine performance?
No. Final performance depends on resin, formulation, film dimensions, operating conditions and the confirmed machine configuration.
What information should a factory prepare?
Prepare the product sample, material and formulation, width, gauge, target output, downstream process, current constraint and project timeline.
