Both are closed-cell, both can be die-cut or CNC-milled, and both appear in <a href=\"https:\/\/tadapack.com\/news\/custom-packaging\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">Custom Packaging<\/a> programs for electronics, medical devices, and premium retail. Yet their mechanical behavior diverges sharply under sustained load and repeated impact. This guide breaks down the differences using 2026 industrial specifications.<\/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 (Ethylene-Vinyl Acetate)<\/strong> is a copolymer foam, typically 18\u201333% vinyl acetate content for packaging grades. Its defining traits are flexibility, high resilience, and a soft hand-feel that makes it the default for presentation trays and tool-case inserts. Density ranges from 45 to 140 kg\/m\u00b3; hardness spans roughly 20\u201360 Shore C.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>XLPE (Cross-Linked Polyethylene)<\/strong> is polyethylene chemically or radiation cross-linked after extrusion. The cross-linking creates a finer, more uniform cell structure with superior dimensional stability. Densities typically run 30\u2013115 kg\/m\u00b3, with compression resistance significantly higher than EVA at equivalent thickness.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Mechanical Performance Comparison<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">The metrics that matter most in protective packaging are compression set, cushioning curve performance, and recovery after repeated impact.<\/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;'>Compression set:<\/strong> EVA typically shows 5\u201315% set after 22 hours at 25% deflection (ASTM D3574). Cross-linked PE foams test lower at 2\u20137%, meaning XLPE recovers better under sustained static loads.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Shock absorption:<\/strong> EVA&#8217;s elastomeric nature absorbs a broader energy range, often sustaining drops from 90\u2013120 cm for fragile goods in the 25\u201350 g deceleration window. XLPE excels under repeated impacts and heavy static loads where EVA would gradually take a permanent set.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Thermal and chemical resistance:<\/strong> XLPE operates from roughly \u201360\u00b0C to +90\u00b0C and resists oils, solvents, and dilute acids. EVA softens earlier (service ceiling near 70\u00b0C) and can be plasticized by hydrocarbons.<\/li>\n<\/ul>\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;\">XLPE 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;\">Compression set (ASTM D3574)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">5\u201315%<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">2\u20137%<\/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;\">Typical density<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">45\u2013140 kg\/m\u00b3<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">30\u2013115 kg\/m\u00b3<\/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;\">Max service temp<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">~70\u00b0C<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#334155; font-size:0.9rem;\">~90\u00b0C<\/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;\">Indicative cost (per bd-ft)<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#059669; font-weight:600;\">$4\u20138<\/td>\n<td style=\"border:1px solid #e2e8f0; padding:12px 16px; color:#059669; font-weight:600;\">$5\u201310<\/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;'>Processing and Fabrication Differences<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Both foams convert well, but not identically:<\/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;'>Die-cutting:<\/strong> EVA cuts cleanly at 2\u2013100 mm thickness with sharp steel-rule dies.

For a 50 kg sustained load, an XLPE pad at 20 mm may outperform a 30 mm EVA pad, cutting material use ~30%.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">On sustainability: both are polyolefin-family plastics (PE-based), recyclable under resin codes 4\/6 in commercial streams where accepted. Under the EU Packaging and Packaging Waste Regulation (PPWR) and growing U.S. state EPR schemes (California SB 54, Oregon, Colorado) now enforcing fees in 2026, weight-based EPR fees apply similarly to both foams\u2014recyclability documentation and PCR content claims are increasingly required in supplier datasheets. Neither foam is broadly curbside-recyclable; consider water-soluble or molded-fiber alternatives for single-use e-commerce inserts where EPR costs are material.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Which Foam Should You Specify?<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>Specify EVA when:<\/strong> the foam is visible, contacts the product surface, requires lamination to fabrics or velcro, or spans a wide shock-energy range in moderate-weight applications.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>Specify XLPE when:<\/strong> loads are heavy or sustained, the package faces multiple handling cycles or export transit, operating temperatures exceed 70\u00b0C, or chemical resistance is required.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">For hybrid designs, laminate a 3\u20135 mm EVA contact layer over an XLPE structural core\u2014this combination is now standard in medical device kits and premium toolcases, delivering presentation quality with transit-grade durability.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Run drop-test validation per ASTM D4169 or ISTA 3A before finalizing.
