- Packaging Information
HDK® N20 NUTRITION is offered in following packaging:
- Pallet with paper bags: 10 kg bags
- Big bags: 150 kg (big bags on pallets)
The smallest package size leaving our plant are the pallets, protected against humidity by a heat shrinkable foil.
Storage & Handling
- Storage Information
HDK® N20 NUTRITION should be stored in the original packaging in dry storage areas. Due to the high surface area HDK® adsorbs volatiles and should be protected from humidity and volatiles. If single bags are taken away from an original pallet, the remaining bags of this pallet must again be protected against humidity and volatiles.
