Getting custom boxes for cosmetics wrong on either axis destroys margin \u2014 damaged goods trigger replacements, while overbuilt structures inflate dimensional-weight charges. This guide consolidates the board grades, flute selections, and compliance benchmarks beauty brands should demand from converters in 2026.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">For the broader sourcing framework, start with our pillar 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;'>Board Selection: ECT, Mullen, and GSM Benchmarks<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Cosmetic cartons typically run between two structural families:<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>Folding cartons (paperboard).<\/strong> Solid Bleached Sulfate (SBS) at 300-400 GSM remains the retail default for lipsticks, serums, and compacts.
