Stratocell® E is a medium-light grade of material, with a density of 24kg/m3.
A closed-cell polyethylene foam, Stratocell® E, provides a good balance of cushioning performance, multi-drop shock absorption, and affordability. Stratocell® E is typically selected over lighter materials for applications requiring increased protection and the ability to survive repeated drops, while reducing material costs and total package weight compared to higher-density grades. As such, it is a popular choice for packaging across retail goods, moderately heavy consumer goods, and sub-assembly components.
Our team of foam experts at Polyformes can provide free, impartial advice on the best foam grade (and type) for your specific product, industry or application. We can, as Sealed Air partners, also supply both material or bespoke foam packaging as required.
