Recycled Paperboards 

are made from pre- and post-consumer waste. Pre consumer waste is mill conversion waste - in other words, paper products that haven't made it to market.

is paperboard that is bleached, which gives the sheet a clean, white appearance all the way through. The bleaching process degrades and weakens the "virgin" fibers, which, in turn, has some effect on the strength of the sheet.
