USPS Laminated Piece Rulings 

Confirming in writing from USPS that if you weren’t mailing plastic postcards before April 6, 2009, automation letter-size mail pieces must be made of paper!

Since this caveat created an un-level playing field for mailers, the PCSC has approved
laminated mail pieces for automation prices on a case by case basis.
In a joint effort, between the PCSC, Engineering, Operations Integration, a matrix of
potential standards was developed, and mail piece are being approved using this matrix.
