Ethafoam

Ethafoam

A low-density plastic foam made by expanding polyethlene approximately 30 times in volume. Excellent chemical resistant and energy absorption under impact, low water absorption and water-vapour transission, good insulation value, no odour, easily fabricated. Available in densities shapes such as planks, sheets and rounds. Ethafoam is a true cushioning medium, able to sustain its resilience under repeated impact.

Also available in Anti Static (EF220AS) and Flame Retardant (EF4101FR) Grades at the 35kg/m3 density.

Lamdex/Stratocell

Sealed Air have purchased the non-crosslinked foam business from Dow Chemical. As there is a similarity of products in some areas, the Lamdex material will shortly be discontinued and replaced with Stratocell. (Ethafoam is still produced and all densities and types are available from the UK supplier Polyformes Ltd.)

Stratocell® Multi-Layer Foam Plank

Our line of Stratocell® foams feature up to 100mm of laminations improving product performance.

Stratocell® Laminated Polyethylene Foam Plank

Light Density: Cost-efficient cushioning protection available for today's lighter weight products. Its exceptionally high strength-to-weight ratio reduces cube, and costs, by providing superior protection using less material than many alternative packaging methods.

Medium Density: Provides cushioning protection against repeated shock, comparable to conventional extruded plank, but with a softer surface that fabricates more easily and heat-bonds without skiving.

Stratocell® Plus Special Density Foam and Film Laminates

Multi-layer plank with a high strength Cellu-Cushion® Foam laminate Backing

Provides all the proven benefits of our laminated plank, plus the added lamination which is used as a hinge when designing cushion packs. Resilient, lightweight Stratocell® Plus foam laminates provide outstanding protection for a wide range of packaging applications while allowing lay-flat cost efficient designs that can also save storage and shipping volume.
