There is no FDA-issued certificate for a finished bag. Compliance is a supply-chain property: each resin, additive, coating, and adhesive must be cleared under the applicable sections of Title 21 of the Code of Federal Regulations (CFR), specifically <a href=\"https:\/\/www.ecfr.gov\/current\/title-21\/chapter-I\/subchapter-B\/part-177\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">21 CFR 174-186 covering indirect food additives<\/a>.

Regulatory Foundations: 21 CFR Resin Clearances<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">FDA grade bags for food packaging are typically built from resins cleared under:<\/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;'>21 CFR 177.1520<\/strong> &#8211; Olefin polymers (PE, PP) for dry and fatty foods.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>21 CFR 177.1630 \/ 177.1506<\/strong> &#8211; PET and nylon for retort and high-temperature use.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>21 CFR 176.170 \/ 176.180<\/strong> &#8211; Paper and paperboard in contact with aqueous and dry food; 176.180 governs dry food with a grease-resistant surface.<\/li>\n<\/ul>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Critical caveat: a cleared resin does not automatically make the bag compliant. Slip agents, colorants, inks, and solvent-based laminating adhesives each need their own clearance. Amines-based slip (EPA\/oleamide) can migrate into fatty foods at rates exceeding thresholds; COF-modified metallocene PE is increasingly specified for fatty-food contact instead.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>2. Structural Specifications That Matter in Procurement<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">For flexible film bags, specify GSM (grams per square meter), gauge in microns, and seal strength in N\/15mm per ASTM F88. A 60-80 micron coex PE bag with a 5-layer structure (typically mPE\/PA\/mPE tie layers) delivers the puncture resistance needed for IQF or coffee applications. For multiwall paper sacks, structural performance is governed by burst (Mullen, kPa) and tensile energy absorption rather than film metrics.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Complementary structures to consider alongside FDA-cleared liners include formats covered in our <a href=\"https:\/\/tadapack.com\/news\/corrugated-flutes\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">corrugated flute<\/a> deep-dive for transit shippers pairing with inner food-contact bags.<\/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;\">Structure<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Key Metric<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">Typical Value<\/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;\">Mono-PE film bag<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Seal strength<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">18-30 N\/15mm<\/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;\">5-layer coex (PA tie)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Puncture resistance<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">4-8 N pin hole<\/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;\">Kraft multiwall sack<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Burst (Mullen)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">220-320 kPa<\/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;\">Paper-based barrier<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">GSM<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">80-120 GSM<\/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;'>3.
