The USPS has published a notice in Friday's Federal Register revising the standards for polywrap film used on automation-rate flat-size mail. The new standards provide one set of specifications for automation polywrap and improve USPS ability to process poly-wrapped pieces on their primary flat-mail processing equipment. The effective date for the new polywrap is February 4th for manufacturers and March 3rd for mailers.
Please follow the link outlining standards published in the Federal Register.
