Both are closed-cell polyolefin-family materials, but their performance envelopes diverge sharply under compression, reuse cycles, and cost pressure. This guide breaks down the technical differences that matter for e-commerce inserts, retail presentation trays, and industrial dunnage.<\/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: Chemistry and Cell Structure<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>EVA foam<\/strong> copolymerizes ethylene with 10\u201340% vinyl acetate, producing a fine, uniform cell structure (typically 0.2\u20130.5 mm cells) with elastomeric recovery.
