EPS(Expandable Polystyrene) is a lightweight, rigid, plastic foam material produced from solid particles of polystyrene. As it is made of 95% air, it is therefore extremely safe and above all, non-toxic. Depending on the products, their type of container for transportation, and the amount of protection required and movement allowed, will decide whether to use chips or beads for the transporting. Beads normally for small objects with reduced packing space.
