The United States Postal Service® has developed a new, orange plastic mailbag. These mailbags are made from 100 percent polypropylene plastic and are secured with the same Velcro closure used on the clear domestic mailbags.
Use the new mailbag (shown here) for Priority Mail® and mail transported through the air network:
The new mailbags feature an opaque plastic sack material that eliminates scan errors during transportation. Additionally, the new mailbags offer two-layer construction, which prevents moisture or contaminates from entering or leaking from the mailbags after they are sealed.
The new mailbag is now available to all Mail Transport Equipment (MTE) customers:
n Order the new mailbags from Mail Transport Equipment Service Centers (MTESCs) through the Mail Transportation Equipment Ordering System (MTEOR).
n When ordering from MTESCs through MTEOR, the identification number for the new plastic mailbags is EIRS 12PV.
