What Makes High Density EPP Boxes Different?
La mousse EPP haute densité équilibre la résistance aux chocs, résistance et recyclabilité meilleures que l'EPS ou l'EPE. Each box is made by expanding polypropylene beads into a closed cell foam. The density range of 15 100 kg/m³ (with high density grades up to 260 kg/m³) allows engineers to tailor strength and insulation to your specific needs. Unlike EPS (polystyrène élargi), which tends to crack after one impact, or EPE (polyéthylène expansé), which cannot absorb shocks effectively, EPP springs back to its original shape after repeated compression. Because the material is a single thermoplastic, it is 100 % recyclable and maintains performance across hundreds of cycles.
Explication élargie
From a manufacturing perspective, EPP’s closed cell structure gives it remarkable resilience. Chaque perle est fusionnée sous chaleur et pression, forming a rigid network of sealed pockets that trap air and dampen vibrations. This means you can drop a high density EPP box during loading and it will regain its shape without losing cushioning ability. EPS is lighter and cheaper but becomes brittle when dropped, while EPE is more flexible but has inferior impact absorption. Qualités haute densité (40 60 kg/m³ or higher) offrent une résistance et une isolation maximales mais pèsent légèrement plus, so the right density depends on your payload and journey length. Surtout, EPP maintains structural integrity from −40 °C to +110 °C, making it suitable for both ultra cold pharmaceuticals and hot meal deliveries without deformation.
Mechanical properties and benefits
| Paramètre | Gamme typique | Bénéficiez pour vous |
| Densité (kg/m³) | 15 - 100 (personnalisé jusqu'à 260) | Adaptez la résistance et l’isolation; higher density equals greater durability but slightly higher weight |
| Absorption d'énergie | 20 - 40 kj / | Protects fragile goods; box rebounds after shocks |
| Résistance à la compression | 0.3 - 2.5 MPa | Handles heavy loads without deformation |
| Plage de température | –40 °C à +110 °C | Supports cold vaccines, frozen foods and hot meals |
| Absorption d'eau | < 0.3 % | Resists moisture, preventing mold and keeping insulation effective |
| Réutilisabilité | Hundreds of cycles | Spreads cost over many shipments and reduces waste |
Conseils pratiques
Choose the right density: For heavy payloads or long journeys, opt for high density foam (40 - 60 kg/m³) to maximise strength and insulation. Lighter loads might benefit from medium density to save weight.
Use appropriate ice or gel packs: Combine your high density EPP box with phase change packs tailored to your temperature range (2–8 °C for biologics or –20 °C for frozen foods).
Ensure tight closures: Choose boxes with flush or hinged lids and gaskets to minimise air leakage.
Évitez de trop remplir: Laissez de l'espace autour du contenu pour la circulation de l'air; overpacking can create hot spots.
Vraie cas: Lors des campagnes de distribution de vaccins, health providers replaced single use EPS coolers with reusable high density EPP boxes. The boxes absorbed shocks and maintained internal temperatures with ice packs, reducing product loss and eliminating thousands of disposable containers.
How Do High Density EPP Boxes Improve Cold Chain Performance?
Superior thermal insulation distinguishes high density EPP boxes from many alternatives. Their closed cell structure traps air and slows heat transfer, functioning like a thermos. Studies show EPP boxes with densities around 30 kg/m³ provide better insulation than comparable plastic or metal containers while being much lighter. This ensures vaccines stay within the narrow 2–8 °C range or frozen foods remain at –20 °C for extended periods. The foam resists water and chemicals, so humidity or leaks do not compromise insulation.
Durabilité inégalée is another advantage. High density EPP boxes are resistant to impact, chemicals and moisture, allowing them to be reused for years. Unlike EPS, which often cracks after one trip, EPP survives rough handling and preserves its cushioning performance. The collapsible design of many boxes saves up to 60 % of storage space when empty, reducing return shipping costs. Reusable EPP boxes also support sustainability because they are 100 % recyclable and easy to clean.
Superior insulation and reusability
High density EPP boxes leverage thermal resilience from –40 °C to +110 °C to maintain cold chain integrity across various products. The closed cells and inert gas inside each bead prevent convection and conduction, slowing heat flow. In real world tests, EPP boxes paired with phase change materials kept mRNA vaccines potent through multi day shipping at –90 °C, while cheaper EPS coolers failed. Because EPP is non porous and water resistant, the boxes remain hygienic and can be sanitized easily.
EPP vs EPS vs EPE: feature comparison
