As part of our broader coverage of <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>, this guide breaks down the actual engineering specifications, cost economics, and failure modes that determine whether CCNB is the right substrate for your SKU.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>What Is Clay Coated Newsback Board?<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">CCNB is a multi-ply recycled paperboard constructed from mixed recovered fiber. The top ply is finished with a clay-based coating that delivers a smooth, bright white printing surface optimized for offset lithography. The reverse side\u2014the &#8220;newsback&#8221;\u2014remains uncoated gray, made from lower-grade recycled fiber including old newspapers, which is where the grade gets its name.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">The coating layer is the commercial differentiator. Without it, recycled board cannot hold fine halftone dots or support high-ink-coverage graphics. With it, CCNB achieves print resolution comparable to virgin SBS at a substantially lower material cost, which is why it dominates secondary packaging where the board itself never touches food or heavy contents.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Key Technical Specifications<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Standard commercial CCNB in 2026 runs the following benchmarks:<\/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;\">Property<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Typical Range<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Engineering Note<\/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;\">Caliper<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">0.30\u20130.50 mm<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Measured per ISO 534<\/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;\">Basis weight<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">250\u2013400 GSM<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Higher GSM = stiffer carton<\/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;\">Top brightness<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">80\u201388% ISO<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Coated side only<\/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;\">Moisture content<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">6\u20138%<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Controls warp and curl<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Stiffness is the most commonly mis-specified parameter.
