Pallet with paper bags: 10 kg bags.
Storage & Handling
- Storage Information
HDK® N20 PHARMA 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.
