EXPANDABLE POLYSTYRENE

Expandable raw material SPAN-PACK®

Expandable polystyrene raw material SPAN-PACK® is sold unexpanded. Solid resin particles are expandable because they contain a blowing agent inside.

 

 

When heated with steam they expand up to 50 times its original volume creating multitude of microscopic cells. Particles are sold in different shapes to fullfill particular packaging needs.Once expanded we will obtain a low density foamed polystyrene "peanuts"

How it is sold?

Expandable SPAN-PACK® is supplied as unexpanded solid particles packed in 500 or 1000 Kg. cardboard octabins. To slow evaporation of the blowing agent  and last longer shelf life the product it is protected with a multilayer plastic bag.

Pallet size is 1100 x 1100 Total high is 1990 to 2190 depending on product reference.

How many octabins we can load in a container

For a 20 ft conainer we usually load 10 octabins 950 / 1000 Kg each, or 20 double stacked octabins 450 / 500 Kg each. In a 40 ft container we can load 20 / 22 octabins of 1 Ton each. Some high cube containers can fit 24 octabins. Pallet size is 1100 x 1100 mm. We request a minimum 12.5 m. length trailer for road deliveries.
