Product Detailed Description
The Engineering of Flute
Corrugated construction combines flat linerboard with wavy fluted medium. Arc geometry creates strength through form rather than material mass. Compression resistance, cushioning performance, and material efficiency result.
We manufacture corrugated mailers across flute profile and wall specification range, optimizing protection to content requirement and cost parameter.
