An ESD EVA foam tray is a thermoformed anti-static packaging solution designed for the storage, transport, and assembly of electrostatic-sensitive devices (ESDs).
Using a hot-pressing process, the EVA foam is molded under controlled temperature and pressure, forming a rigid yet resilient structure that combines the properties of both a plastic tray and cushioning foam.

Compared with traditional ESD boxes + EVA inserts, the hot-pressed EVA tray integrates both strength and shock absorption into a single structure — streamlining packaging, improving efficiency, and reducing assembly costs.

The ESD EVA foam tray is widely adopted in industries requiring both static protection and physical stability:

· Semiconductor & Electronics – for PCBA, IC modules, sensors, and connectors

· AI Server & Communication Equipment – power modules, server blades

· Robotics & Automotive Electronics – battery controllers, optical sensors

· Medical & Laboratory Devices – contamination-free handling and precision assembly

In these fields, hot-pressed EVA trays outperform general ESD boxes by offering high load capacity, shock absorption, and repeatable use.

�� 3. How It Solves Common Customer Pain Points: 

 Customer Challenge                       Hot-Pressed EVA Tray Solution                            

Boxes require additional EVA inserts          One-piece design — integrated cushioning & support

Weak structural strength of foam inserts      Molded high-density EVA, 30–50% higher compression strength

Poor fit or frequent replacement             Custom cavity design, reusable and dimensionally stable

Static discharge risk                        Permanent anti-static properties (10⁴–10⁹ Ω)

High logistics or rework cost                Lightweight, recyclable, low maintenance

 �� 4. Manufacturing & Customization

YUFA Polymer specializes in custom ESD foam trays using hot-press molding.
We design and manufacture according to your part geometry and factory workflow.

Customization options:

· Tray size and cavity layout

· Surface texture (smooth or embossed)

· Resistance value range (10³–10⁹ Ω)

· optional logo printing

· Stackable or nestable structure

Each tray undergoes resistance testing and dimensional inspection before shipment — ensuring reliability for high-end ESD management.

�� 7. Final Thoughts

If you’re still using a combination of ESD box + EVA insert, it’s time to rethink your strategy.
Our hot-pressed ESD EVA foam trays simplify logistics, reduce costs, and provide superior electrostatic protection — all in one integrated structure.

Let’s redefine your ESD packaging together..
