Corrugated board

High quality cardboard made from 100% pure cellulose; rigid and resistant to mechanical damage, 3-layer corrugated cardboard. 

When choosing corrugated cardboard, it is necessary to take into account the serious dangers and risks related to its use in archival storerooms:
- nesting of insects, e.g. fishworms, in cardboard tunnels;
- flammability;
- low resistance to prolonged immersion in water.
