Ethafoam® 150 is the lowest-density material in the Ethafoam® range, at approximately 25kg/m³ (1.5 pcf).
Manufactured by Sealed Air, Ethafoam® 150 is a closed-cell polyethylene foam used almost exclusively for packaging. It’s generally preferred over higher-density grades like 220 or 400 for applications requiring lightweight, cost-effective cushioning for low-to-medium weight, fragile items. Alongside its excellent recovery characteristics – returning to its original shape quickly after compression – its low density helps Ethafoam® 150 minimise shipping weight and costs.
At Polyformes, we are official Sealed Air partners. As such, we can supply your business with Ethafoam® planks in standard or custom sizes, as well as a wide range of alternative foam materials. We can also help identify the most suitable foam for your specific requirements
