What Makes High Density EPP Boxes Unique?
Réponse directe: High density EPP boxes have a rigid closed cell structure that resists impact, cushions fragile goods and provides exceptional thermal insulation. Unlike brittle polystyrene foam, EPP springs back after multiple compressions and can be reused hundreds of times. Manufacturers can adjust foam density from 15 kg/m³ to 260 kg/m³, tailoring strength and insulation to your payload.
Explication détaillée: Each EPP box is moulded from expanded polypropylene beads into a network of tiny closed cells. These cells trap air, which slows down heat transfer and cushions shocks. Compared with expanded polystyrene (PSE) et polyéthylène expansé (EPE), EPP maintains its shape after repeated impacts and temperature fluctuations. High density grades (40–60 kg/m³) offer greater compressive strength and insulation but weigh slightly more. The material remains stable from −40 °C to +110 °C, making it suitable for frozen goods, chilled vaccines and even hot catering deliveries.
Physical and Thermal Properties of High Density EPP
EPP performance at a glance:
| Propriété | Gamme typique | Exporter insight | Ce que cela signifie pour vous |
| Densité (kg/m³) | 15–100 kg/m³ (personnalisé jusqu'à 260 kg/m³) | Higher density increases strength and insulation but adds weight | Match density to payload weight and journey length to balance protection and cost |
| Absorption d'énergie (kj /) | 20–40 | Measures the foam’s ability to absorb shocks | Protects glass vials, electronics and delicate foods during export |
| Résistance à la compression (MPa) | 0.3–2,5 | Determines how much weight the box can bear without deforming | Allows secure stacking and palletisation in warehouses |
| Operating temperature (°C) | −40 à +110 | Indicates temperature range for safe use | Suitable for deep frozen vaccines, chilled seafood and hot meal delivery |
| Absorption d'eau (%) | < 0.3 | Non porous surface resists moisture | Prevents mould and maintains insulation even in humid environments |
| Réutilisabilité (cycles) | Des centaines | Number of times the box can be reused | Spreads cost over many shipments and supports sustainability |
Conseils et suggestions pratiques
Match density to your payload: Choose 40–60 kg/m³ foam for heavy or long haul shipments; medium densities suit lighter goods and reduce transport costs.
Use appropriate cooling packs: Pair your EPP box with phase change materials (PCM) or gel packs matched to the desired temperature range to extend cooling time.
Ensure secure closures: Select flush or hinged lids with gaskets to minimise air leakage and maintain stable temperatures.
Évitez de trop remplir: Leave air space around contents for proper circulation; overpacking can create hot spots.
Exemple du monde réel: Lors des campagnes de distribution de vaccins, providers replaced disposable EPS coolers with EPP boxes and ice packs. The EPP boxes absorbed impacts during rough handling and maintained target temperatures, reducing product loss and eliminating thousands of single use boxes.
How Do High Density EPP Exporters Enhance Sustainability and Reduce Costs?
Réponse directe: High density EPP exporters champion sustainability by offering reusable, fully recyclable containers. Unlike single use polystyrene coolers, EPP boxes can be cleaned and reused hundreds of times, reducing waste and lowering your long term packaging costs.
Explication détaillée: EPP foam is a single polymer material that is easy to recycle. Exporters collect used boxes, clean them and remould the foam into new products, closing the loop. Because one EPP box can replace hundreds of disposable containers, landfill volumes and production energy drop significantly. Though the initial cost is higher than EPS, reuse programs often break even after only a few dozen cycles. Environmental benefits include a smaller carbon footprint, reduced demand for virgin materials and improved brand perception.
