For the base foam there are three foams available:
ProCell is a High-Density foam with a velvet feel. It has a high-temperature resistance. This foam is not affected by fluids like water or oil. This foam is perfect for heavier objects and is also used for presentational purposes. In Europe, this is the most used foam.
EcoCell is also, a High-Density foam which can be compared to our ProCell. But, it has bigger cell structure and feels a bit more 'dry'. The unique aspect of this foam is that we can recycle 100% of the scrap material. We grind it, melt it to blocks and send them back to the factory for a cradle to cradle use. Because we promote the ecological aspects of this foam we have made it more economical.
SoftCell is a soft, Low-Density foam. Perfect for packing lighter objects that need more padding. Think of camera body's, glass or artwork. This foam is just like the EcoCell more economically priced. The foam feels like a sponge and absorbs water or other fluids.
So, to sum it up,
It's up to you to choose any of these three options:
ProCell is a High-Density foam with a luxurious feel.
EcoCell is a recyclable foam with a bit more rough feel.
SoftCell has a 'sponge' feel, for the most delicate purposes.
