Expanded Polypropylene (EPP) foam sheets are widely used in packaging, logistics, and industrial applications due to their excellent balance of strength, cushioning, and durability. One of the key factors that determines EPP performance is density, as different densities are designed to meet different functional requirements.

Low-density EPP sheets (typically 20–40 g/L) are lightweight and cost-efficient. They offer good shock absorption and are commonly used for protective packaging, cushioning layers, and disposable or semi-reusable transport solutions.

Medium-density EPP sheets (around 40–60 g/L) provide an ideal balance between strength and resilience. These densities are widely used for electronic packaging, display modules, automotive components, and reusable logistics systems, where both impact resistance and dimensional stability are required.

High-density EPP sheets (60 g/L and above) deliver superior rigidity, load-bearing capacity, and long-term durability. They are suitable for heavy-duty packaging, structural support, tooling bases, and industrial applications that require precise fit and repeated use.

By selecting the appropriate density, EPP foam sheets can be optimized for weight reduction, protection performance, service life, and cost efficiency. With customizable thickness, size, and optional anti-static properties, EPP sheets offer a versatile and sustainable solution across multiple industries.
