Is PU foam better than EVA?
Not universally. PU is softer; EVA is firmer and cleaner for case inserts. The right choice depends on product weight, appearance, handling, and shock risk.

When PU foam works best
PU foam can protect products that are sensitive to scratches, vibration, or light impact. It is a good option for instruments, samples, fragile accessories, medical-adjacent devices, electronics, and retail packaging where a softer touch is important.
Material selection
Density, compression, thickness, and cell structure affect performance. A low-density foam may feel soft but fail under heavier products. A higher-density PU foam can support better, but may increase cost and reduce compression.
Packaging design
PU foam can be used as bottom pads, top lid foam, side protection, cavity inserts, and layered packaging. For export shipments, it is often combined with carton strength, product bagging, and outer packaging requirements.
