Unlike printing, it adds zero ink, laminate, or foil\u2014the effect comes purely from substrate deformation. For B2B buyers evaluating premium folding cartons, rigid boxes, or display graphics, understanding the mechanics explains both the cost structure and the failure modes.

The governing rule: <strong style='color:#0f172a;'>relief depth should stay within 25\u201330% of substrate caliper<\/strong>. A 0.40 mm (16 pt) SBS sheet tolerates ~0.12 mm depth; pushing beyond that ruptures surface fibers, causing whitening, cracking on folds, and a measurable drop in tensile strength.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Corrugated embossing is flute-dependent. Embossing across a flute vertex on C-flute (4.0 mm) or BC-flute (7.0 mm) collapses the arc, crushing cushioning and losing relief definition. E-flute (1.5 mm) litho-laminated to SBS liner is the practical corrugated embossing platform. Fiber direction also matters: embossing parallel to the machine direction (MD) produces sharper shoulders; cross-direction embossing softens edges and raises cracking risk on recycled boards.<\/p>\n<div class=\"table-responsive\" style=\"overflow-x:auto; margin: 28px 0; border:1px solid #e2e8f0; border-radius:10px; box-shadow:0 2px 8px rgba(0,0,0,0.03);\">\n<table style=\"width:100%; border-collapse:collapse; text-align:left; background:#ffffff;\">\n<thead>\n<tr style=\"background:#f8fafc; border-bottom:2px solid #e2e8f0;\">\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Parameter<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Typical Spec<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Failure Threshold<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom:1px solid #e2e8f0;\">\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; font-weight:600; color:#0f172a;\">Relief depth<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">\u22640.5 mm cartons<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">>30% caliper<\/td>\n<\/tr>\n<tr style=\"background:#fafafa; border-bottom:1px solid #e2e8f0;\">\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; font-weight:600; color:#0f172a;\">Die temperature<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">90\u2013120\u00b0C<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">>140\u00b0C scorch<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #e2e8f0;\">\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; font-weight:600; color:#0f172a;\">Best substrate<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">300\u2013450 GSM SBS<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\"><250 GSM webs<\/td>\n<\/tr>\n<tr style=\"background:#fafafa; border-bottom:1px solid #e2e8f0;\">\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; font-weight:600; color:#0f172a;\">Registration tolerance<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">\u00b10.2 mm<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">>0.5 mm visible<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Structural Impact and Compliance Testing<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Because embossing compresses fibers, engineers must verify it does not degrade structural performance.
