A foam insert is the part of the pack that holds the product. Bofeng Foam die-cuts and CNC-routes XPE, IXPE and IXPP inserts to a product outline.
1. XPE Foam Inserts
Material properties
- Closed-cell structure with uniform density.
- Good compression recovery under repeated loading.
- Water-resistant, moisture-resistant and resistant to most chemicals.
Where it fits
- Consumer electronics: frame padding for smartphones and tablets.
- Industrial equipment: die-cut inserts for precision instruments and mechanical components.
- Cold chain: the thermal layer for insulated containers.
Why specify it
- Die-cutting takes complex internal geometry, so the cushioning follows the product outline.
2. IXPE Foam Inner Lining
Material properties
- Electron-beam cross-linking gives a finer, more uniform cell structure than XPE.
- Can be made permanently anti-static.
- Higher resilience under repeated compression.
Where it fits
- Medical devices: packaging for surgical instruments and diagnostic equipment.
- Premium electronics: anti-static inserts for semiconductor components and precision circuit boards.
- Food equipment: linings that can be wiped clean between uses.
Why specify it
- Anti-static performance is built into the material rather than coated on, so it does not wear off.
3. IXPP Foam Inserts
Material properties
- Higher rigidity than the polyethylene foams, so it carries load as well as absorbing it.
- Better heat resistance — up to 140 °C maximum service temperature.
- Light for its strength, with good ageing resistance.
Where it fits
- Automotive components: structural padding for engine parts and electronic control units.
- Heavy equipment: support frames for industrial tools and large instruments.
- Returnable packaging: durable linings for logistics containers.
Why specify it
- It suits composite inserts that have to hold a shape under load, and being reusable it cuts packaging cost over a return loop.
Application examples
- Consumer electronics: ultra-thin IXPE shock-absorbing inserts for smart wearables.
- Medical devices: custom XPE composite inserts for surgical robot accessories.
- Industrial manufacturing: IXPP structural transport inserts for automotive components.
