This breakdown gives procurement and engineering teams the specification data needed to select correctly \u2014 the first time.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Material Fundamentals<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>EVA foam<\/strong> is a closed-cell copolymer of ethylene and vinyl acetate (typically 10\u201340% VA content). Higher VA content yields softer, more elastic material with rubber-like recovery. Density ranges from 33\u2013200 kg\/m\u00b3, with common packaging grades at 38\u201365 kg\/m\u00b3.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>Polyethylene foam (EPE)<\/strong> is a closed-cell expanded polyethylene produced via butane or CO\u2082 expansion. Densities run lower \u2014 25\u201345 kg\/m\u00b3 for most shipping applications \u2014 giving it the best strength-to-weight ratio among commodity foams.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Both are cross-linked or non-cross-linked; cross-linking improves cell uniformity and dimensional stability at a 15\u201325% cost premium.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Head-to-Head Specification Comparison<\/h2>\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;\">EVA Foam<\/th>\n<th style=\"border:1px solid #e2e8f0; padding:12px 16px; background:#f8fafc; color:#0f172a; font-weight:700; font-size:0.92rem;\">PE (EPE) Foam<\/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;\">Density range<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">33\u2013200 kg\/m\u00b3<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">25\u201345 kg\/m\u00b3<\/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;\">Compression set (50%)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\"><5%<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">8\u201312%<\/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;\">Chemical resistance<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Excellent (oils, solvents)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Good (acids, alkalis)<\/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;\">Relative unit cost<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">High (~1.5\u20132\u00d7)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">Low (baseline)<\/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;'>Cushioning Performance<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">For drop protection, EPE delivers reliable energy absorption for fragile items under 20 kg at competitive cost per cubic foot.

EVA remains flexible at \u221240\u00b0C; standard EPE stiffens below \u221220\u00b0C unless modified. For cold-chain e-commerce, verify low-temperature flexibility on material datasheets.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>2026 Regulatory &#038; Sustainability Context<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Under EU PPWR requirements and expanding US state EPR programs, both foams face pressure on recyclability labeling and recycled-content reporting.
