How Material Selection Impacts Packaging Performance - Foam Packaging Industry

In the world of industrial packaging, not all foam is created equal. Selecting the right protective foam material isn’t just about cushioning — it’s about matching material properties to the demands of the product, environment, and supply chain. At New Edge, we treat material selection as an engineering decision — one that can directly influence product integrity, cost-efficiency, and even sustainability outcomes.

Why Material Choice Matters

Every product faces a unique set of risks — shock, vibration, static electricity, moisture, or temperature fluctuations. The wrong foam can lead to damaged goods, increased returns, or elevated packaging costs. The right foam, on the other hand, becomes a performance asset, protecting the product while optimizing space, weight, and logistics costs.

Let’s explore how various foam types popular in Vietnam’s packaging market compare — and how they are best applied across industries.

1. Polyurethane Foam (PU) — Versatile and Lightweight Cushioning

• Density: Low to medium (20-80kg/m3)

• Structure: Open-cell

• Shock Absorption: Excellent; highly compressible

• Thermal Properties: Poor insulator; mainly used for impact

• Recyclability: Limited (some forms can be reprocessed)

PU foam is a go-to solution for protecting lightweight, delicate, or oddly shaped items. Its soft, flexible, open-cell structure allows it to compress and rebound, absorbing impact and reducing breakage. Ideal for medical devices, optics, and luxury goods, PU can be custom die-cut or CNC-shaped to cradle sensitive components.

Use Case: Shock-absorbing inserts for medical instruments in hard-shell cases.

2. Polyethylene Foam (PE) — Durable, Dense, and Structurally Supportive

• Density: Medium to high (15-250kg/m3)

• Structure: Closed-cell

• Shock Absorption: Very good; firm and resilient

• Thermal Properties: Excellent insulator

• Recyclability: Good (especially non-cross-linked PE)

PE foam is chemically resistant, moisture-proof, and structurally rigid, making it ideal for industrial, automotive, and heavy-duty applications. It holds its shape under pressure, supports heavier products, and provides excellent resistance to compression set.

PE is often used in multi-use returnable packaging, where long-term durability matters. New Edge offers both standard and cross-linked PE foam, depending on the mechanical and aesthetic needs.

Use Case: Foam dividers for automotive parts shipped across continents.

3. Expanded Polyethylene (EPE) — Lightweight and Economical

• Density: Low (16 - 35kg/m3)

• Structure: Semi-closed cell

• Shock Absorption: Good, especially in larger volumes

• Thermal Properties: Moderate

• Recyclability: Excellent

EPE foam is a lightweight and cost-effective solution for bulk packaging and single-use protection. Its flexibility, resilience, and recyclability make it suitable for e-commerce, household goods, and FMCG. EPE foam sheets, rolls, and profiles can be easily shaped for wrapping, blocking, or corner protection.

Use Case: Edge and corner protectors for flat-pack furniture and appliances.

4. EVA Foam — High-Performance Foam with Luxury Appeal

• Density: Medium to high (20 - 150kg/m3)

• Structure: Closed-cell 

• Shock Absorption: Excellent; dense and smooth

• Thermal Properties: Good

• Recyclability: Limited (though reusable and long-lasting)

Ethylene-Vinyl Acetate (EVA) foam is prized for its durability, impact resistance, and visual finish. It’s frequently used in premium packaging where aesthetics, tactile feel, and dimensional precision matter. EVA’s dense and smooth structure gives it a high-end look, while its resilience protects products from high impacts.

Use Case: Premium custom-cut inserts for electronics, tools, or retail kits.

5. ESD Foam — Electrostatic Safety for Sensitive Electronics

• Density: Varies depending on type (antistatic, conductive, dissipative)

• Structure: Can be PE, PU, or EVA-based with ESD additives

• Shock Absorption: Depends on base material

• ESD Protection: Prevents static buildup and discharge

• Recyclability: Limited due to ESD treatments

ESD foam protects sensitive electronic components from the invisible but damaging threat of electrostatic discharge. From circuit boards to microchips, these foams offer measured resistance (Ω range) to safely dissipate static electricity.

At New Edge, we provide both ESD PE and ESD PU in custom shapes, trays, and layered constructions for cleanroom and industrial use.

Use Case: Component trays for microprocessors, sensors, and PCBs during transport and handling.

ESD foam is vital in electronic packaging, providing essential protection against electrostatic discharge that can damage sensitive electronic components during handling, shipping, and storage
