5、 Storage Conditions and Shelf Life
Tinned copper ribbon should be stored in dry and ventilated room, where should be no acid,
alkali, or harmful gas and the indoor relative humidity should not exceed 60%. Place it
horizontally while stacking and avoid the carton extrusion & vertical placement, meanwhile,
the stacking quantity of same products should not exceed five layers or 1 ton. The shelf life
can be up to six months since the production date.
