Corrugated Materials, Flutes & Finishes
Deep technical specifications on board weights, fluting calipers, burst testing, and sustainable water-based coatings.
Corrugated Flute Comparison: E-Flute vs. B-Flute
E-Flute (1/16" / 1.6mm)
Featuring 90 flutes per linear foot, E-Flute delivers the smoothest possible print canvas with virtually no washboarding pattern. It is the gold standard for high-end subscription boxes, cosmetics, jewelry, and luxury retail mailers.
B-Flute (1/8" / 3.2mm)
Featuring 47 flutes per linear foot, B-Flute provides double the cushioning and vertical stacking strength. Recommended for fragile items, glass bottles, hardware, footwear, and payloads exceeding 10–15 lbs.
