Squareness of sheet: Maximum squareness is 0,08% of length of the sheet.

Flatness: The tolerance on flatness of the sheet is maximum 2 mm (height of wave).

Lateral bow: The tolerance on lateral bow is max. 0,1%, (which means 1mm on a fixed sheet length of 1000mm).

Grain size: The grain size, measured according ASTM E112-85, must be ≤100 µm.

Surface quality: Material is chromium-phosphate conversion coated and DOS re-oiled.

Food contact: Aluminium alloys, conversion coating and DOS oil are approved for food contact according to current legislations. (European regulation 94/62/CEE, CONEG, FDA)

 

We are the earliest enterprise that can provide high level can-stock materials for pop-top can-body, can-stock and can-lid in aluminium in China, which is the core supplier for the package in aluminium. We adopt Japan original painting machine and PPG coating that is exclusively used for tank cap, and professionally produces the coated aluminium coils used for making ring-pull and lid of pop can. All the products are tested by the special instrument, and have passed the FDA recognition of the US.
