Tabs and Wafer Seals

Along with the postal rate changes that started today the USPS has also changed the way mail pieces are sealed (self mailers). You can no longer use a 20# sheet of paper folded in 1/2. It is to thin, it must be .009 thick when folded over and regular copy paper (20# is normal copy paper) is around .007. So if you use regular copy paper you need to tri-fold it. For best results you should use a 60# paper for all mailings. This will do two things first, it will meet the minimum thickness and second, 60# does not bleed the copy through.
