?1.Generally we tend to use Pp bag,100 L/bag to load the expanded perlite.
? ?And the jumbo bag,1-1.5M3/bag was also been used by our customer before.
?
2.The expanded perlite is sold by it's volume,so the unit of price will be USD$?? /Cubic meter
?
3.We can load 30m3 to one 20 FCL and 72?m3 to one 40HQ.
