BC and EB double-wall structures combine different flute profiles. Their behavior depends on paper grades, grammage, moisture, box dimensions, scoring and converting quality as well as flute geometry.
Typical decision factors
- BC is often considered where compression, cushioning depth and heavier-duty handling matter.
- EB can offer a thinner profile and smoother surface where print quality, folding detail or space efficiency matter.
- Large panels, long transport routes and humid storage can change the required specification.
- Final selection should be confirmed with a board specification and representative pack test.
Information to share with a supplier
Provide product weight, carton dimensions, stacking pattern, storage humidity, transport route, printing requirements and current failure mode. Flute naming alone is not a complete material specification.
