Noncrosslinked PE foam
The most common material used in the packaging industry. It is an alternative to foamed polystyrene. Production of a PE foam protection doesn’t require costly forms as it is in the case of foamed polystyrene. The uncrosslinked polyethylene foam is pure polyethylene foamed with gas. That material is very well recyclable and in consequence, much more environmentally friendly than foamed polystyrene. The foam has the closed cell structure; it doesn’t absorb water and is impermeable to air. The foam has thermal insulation properties with parameters similar to foamed polystyrene.
The available densities range from 17 to 35kg/m3. As a standard, we offer foam in white, graphite and pink (antistatic properties). We can also produce foam in other colors, provided that the requirements concerning minimum order amounts are met.
The foams are in one extrusion, up to 20mm thick. Thicker foams are welded and consist of several layers.
The foam is most commonly used for production of disposable packaging or thermal insulation.
ETHAFOAM and SYNERGY foam
It is crosslinked polyethylene foam manufactured from a single extrusion. It has the same properties as the noncrosslinked polyethylene foam. It is a noncrosslinked polyethylene foam of the highest quality. It has the closed cell structure. Unlike the normal foam, it is available in a thickness ranging up to 100 mm without the welded layers. The material density ranges from 25 to 57kg/m3.
The foam is applied when a high material durability is required. It is used for protection of heavy items such as machinery and metal parts.
Available colors: white, black, and pink (antistatic).
An interesting variation of this foam is the Synergy foam. It is also noncrosslinked polyethylene foam featuring small cell structure. Thanks to it, the surface of that foam is much smoother and nicer. It looks very similar to crosslinked foam, but it is much cheaper. The material is well suited for attractive decorative boxes.
A polyolefin foam, physically crosslinked. It usually occurs in black/graphite.
The blocks of foam are produced in a similar way as uncrosslinked foam by laminating (welding) of thinner foam layers. The foam obtained in consequence of that process can be up to 100mm thick.
The foam has a closed cell structure. It is a much more durable material than the uncrosslinked foam and is much better suited for processing by milling. The foam is ideally applicable as filling for boxes and reusable packaging, such as rotation packaging used in storerooms. The soft foam structure protects very well against scratches even very delicate surfaces such as brushed aluminum.
The foam has a much better material memory, i.e. after crushing, it recovers to its original shape.
The most popular densities are 28 and 40kg/m3.
XPE and EVA Foam
Chemically crosslinked polyethylene foam. Available in many colors. It is first of all known as material used for the production of sleeping pads. The foam is decidedly far more durable than the uncrosslinked foam and is used when the product shouldn’t be an one-off item.
The foam can also be available in rolls or plates if its thickness exceeds 10mm. The material is well suited for production of sports mats gaskets, or toys.
