How to protect the surface of aluminium cladding sheet

Usually, in order to avoid the surface of the aluminium cladding sheet being scratched, the protection film is attached to a protective film or the paper is separated for long time so as to avoid the scratch caused by the friction between the aluminum round  sheet and the aluminium cladding sheet. At the same time must ensure that the transport time is more solid, so as to avoid sliding problems due to transport, which is easier to cause scratches.
This is because aluminum hardness wants to be much softer than other metals, as long as a slight surface rub will be the surface of many small scratches. So we must be very careful when transporting, handling and processing aluminum sheets.

In addition, the workers need to wear gloves when moving, so that the sweat can be avoided on the surface of the aluminum sheet for bottle caps, because the surface of the aluminium cladding sheet is likely to be corroded or oxidized for a long time. When processing, especially when the shear bending should pay attention to, if the surface quality ratio is high or recommended to stick protective film.
