Difference between rolled copper foil and electrolytic copper foil.
# Process is difference: rolled copper foil (Rolling process),ED copper foil (Electrodeposition process).
# Performance is different ,Strength toughness: rolled copper foil is a flaky crystalline structure, so the strength and toughness is better than electrolytic copper foil, so most of the rolling copper foil used in flexible printed circuit boards.
