HOW CARBONLESS PAPER WORKS?
When writing on the top of multiple ply NCR documents, the pressure from the writing instrument causes the microcapsules (on the back of CB & CFB) break, the contains will react with the developer (on the front of CFB & CF) and finally realize auto copy.
APPLICATION
Carbonless paper is widely used in multiple ply documents such as banking note, ways bills, commercial invoices, stock list, order list, courier way bill, air/ocean way bill, commercial book, pos roll etc.
