Postal Films

Our USPS approved films are used for enclosing magazines, catalogs, and other flat size direct mail pieces in a poly bag. Poly bagging flat size mail saves money on bulk mailings, provides protection from damage due to mail handling and weather; as well as allows for the inclusion of free samples, advertisements and other supplemental material.

Flex-Pak’s postal films meet or exceed the standards outlined in USPS T-3204 and are approved for automation rates.
