Budget protection that punches above its price.
EPE is a closed-cell polyethylene foam made by expanding polyethylene resin. The process leaves small, closed bubbles, giving a soft but durable material with good resilience. It is also called pearl foam, after its shiny, pearlescent finish.
It does not have the premium finish of PE45, but it absorbs shock well at a fraction of the cost. That makes it the pick for high-volume packaging, occasional-travel cases and lightweight gear.

EPE foam properties. Compression strength and density vary together within the ranges above.
Light, cheap, and it still cushions.
The budget option for high-volume packaging or straightforward protection where cost leads the decision.
Adds very little weight to a case or shipment, which keeps freight costs down on volume runs.
Compresses under a drop and springs back, so it keeps absorbing impacts rather than taking a set.
Handles repeated use without much wear, does not absorb moisture, and is 100% recyclable at end of life.
Where EPE shines.
Common applications of EPE foam, also known as pearl foam.
Packaging & Shipping
Protecting electronics, appliances and fragile goods in transit.
Thermal Insulation
Construction, refrigeration and HVAC, on the back of its thermal resistance.
Automotive Interiors
Door panels, headrests and noise reduction components.
Sports Equipment
Impact absorption for helmets, pads and protective gear.
Flotation Devices
Life vests, buoys and other marine equipment. EPE is highly buoyant.
Food Packaging
Non-toxic, so it suits fruit trays and food containers.
