Copper foil is main product in our factory, which can be used in health care area, shielding field, Li-ion battery manufacture, PCB manufacture and also waterproof effect.
We can provide the specific single-matte, double-matte, and double shiny ED copper foil with nominal thickness from 6um to 12 um for the Li-Ion battery; width is from 100mm-1300mm.And the double shiny ED copper foil has the characteristics of the symmetrical structure of both sides, the metal density nearing the copper theoretical density, very low surface profile, and high elongation and tensile strength.
