Postcom.org--Current DMM® standards require mailers to use "clear smooth strapping tightly secured around the bundle" as a way of ensuring that address and presort information on bundles is visible and readable by the naked eye. Recent testing shows that a new strapping with a transparency rating of at least 52 percent when tested using ASTM D1746 - 09, Standard Test Method for Transparency of Plastic Sheeting, methods meets all Postal Service readability requirements. Mailers may begin using this type of strapping immediately - it is more environmentally friendly and provides cost savings to mailers, while continuing to secure bundles in a way that helps the Postal Service process the mail efficiently. We are working on revising the mailing standards for strapping and will use the DMM Advisory to keep you informed.
