2.the process of the production:
 mother coil (made by casting rolling)or DC mother coil(made by  hot -rolled production)
2.Rouging by cold rolling mill
3.Finishing rolling by foil mill
4.Cleaning and straightening by straightening machine
5.Annealing (dangling annealing) to charge the temper
6.Packaging (from the inner to the outer:plastic film,fiber carton,wooden pallet with steel strip tied),
Put the drier into the package to prevent damp by sea.
3.the quality of the aluminum foil
1)the surface of the aluminum foil should be clean,smooth.There is no corrosion,empty,folding,brown staining,
Slotted,add edge,wrinkling ,concave and convex.
2)the surface of the aluminum foil are not allowed to have a serious color difference.
3)the  end surface of the aluminum foil should be clean and tidy,there is no burr,wrong layer,bruising and collapsed.
