Choosing the right ecosystem starts with structural classification, not price negotiation.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Structural Selection: Corrugated vs. Folding Carton<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Corrugated board is defined by flute profile and liner combination. B-flute (\u22483.0 mm) is the Mumbai e-commerce default for boxes under 450 mm on the longest side; C-flute (\u22484.0 mm) carries heavier stacked loads; E-flute (\u22481.5 mm) provides a printable surface for retail-ready shippers.
