Corrugated Polyethylene Foam (EPE) | Protecting fragile electronics/appliances during shipping | Corrugated structure (Base: 2.5mm cell size ▲ Advanced: 2.0mm1), waterproof (ASTM D751) Cushioning: Base 500 kPa ▲ Advanced 600 kPa2 | High shock absorption (15% compression set), lightweight (900 g/m²), recyclable (ISO 14021) | Less durable under heavy loads (max 500 kg/m²) compared to PU foam |
Bubble Wrap | Fragile items like glassware, electronics | Air-filled bubbles (15mm diameter), burst resistance (1000+ punctures, ASTM D3078) Thickness: 0.5–2mm | Lightweight (120 g/m²), noise reduction (35 dBA), easy to use | Limited load capacity (max 200 kg/m²), puncture risk |
Corrugated Cardboard | Heavy items, shipping boxes for appliances | Fluted structure (E-flute 3.2mm), compression strength 350 kPa Thickness: 4–12mm | Sturdy (supports 800 kg/m²), cost-effective ($0.5/m²), widely available | Not waterproof, minimal cushioning (30% compression set) |
EVA Foam | Cushioning in sports gear, medical devices | Closed-cell structure (0.04 g/cm³ density), water-resistant (ASTM D751) Cushioning: 300 kPa compression strength | Flexible (-40°C to 80°C), chemical resistance (ASTM D543), lightweight (800 g/m²) | Degrades over time (5-year lifespan), higher cost ($2/m²) |
Polyurethane Foam (PU) | Heavy-duty protection for automotive parts | High density (0.8 g/cm³), compression strength 800 kPa Thickness: 5–20mm | Durable (supports 1500 kg/m²), long lifespan (10+ years), high load-bearing | Heavy (1600 g/m²), less eco-friendly, expensive ($5/m²) |
Air Cushion Packaging | Fragile e-commerce items, lightweight products | Inflated plastic bubbles (continuous), burst resistance (ASTM D3078) Thickness: 0.3–1mm | Lightweight (60 g/m²), customizable shapes, noise reduction (30 dBA) | Puncture risk, not reusable, limited cushioning (40% compression set) |
