Most buyers specify decoration first and structure second; that order inverts total cost of ownership. This guide covers the decision framework we use at TadaPack for e-commerce and retail programs, aligned to current 2026 press and substrate benchmarks. For channel-level strategy, start with the pillar hub on <a href=\"https:\/\/tadapack.com\/news\/custom-packaging\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">Custom E-Commerce &#038; Retail Packaging<\/a>.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Start With the Board, Not the Print<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Corrugated board is a strength substrate first and a print substrate second. The flute profile and liner combination determine both compression performance and how much ink detail the surface can hold:<\/p>\n<ul style=\"margin:16px 0; padding-left:24px; line-height:1.75; color:#334155;\">\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>B-flute (3.0 mm):<\/strong> The e-commerce default. 125\u2013175 ECT equivalents, flatter print surface than C-flute, ships efficiently.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>C-flute (4.0 mm):<\/strong> Better stacking strength for heavier SKUs; coarser flutes produce visible washboarding under heavy ink coverage.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>E-flute (1.5 mm):<\/strong> Retail-ready cartons and litho-lamination.

Kraft liner (natural, 135\u2013200 GSM) absorbs ink aggressively and shifts color; white-top mottled or clay-coated liners hold registration and Delta-E tolerances below 3.0.
