Packaging, storage and  safety instructions  


This Landercoll HEMC is supplied in 25kgs multilayer paper bags with polyethylene intermediate layer and/or in big  bags. 

One 20'FCL can load 10MT with pallet, 12MT without pallet, and one 40'FCL can load 20MT with pallet, 22MT without pallet.


When kept in clean, dry conditions in its original  packing, Landercoll can be stored for a long time. During  storage a slow loss of viscosity can be measured.  Landercoll absorbs water from moist air. Once opened,  container must be resealed and kept tightly closed. Like all fine particle organic substances, cellulose ethers constitute a dust explosion hazard. Dust  formation and deposits must be kept to a minimum so  that no ignitable dust/air mixtures can form. Ignition  sources such as naked flames, hot surfaces, sparks  and static electricity should be avoided.
