What is a USPS Priority Mail Tyvek Envelope?

USPS Priority Mail Tyvek Envelopes are special envelopes for the USPS Priority Mail service to ship documents and other items that need to resist weather and other environmental conditions. Tyvek envelopes are discreet, free to order, and the perfect package to send documents, pictures, and other important items. The envelope is designed to withstand the rough nature of shipping while keeping your documents safe and secure.


Tyvek is designed with keeping your package safe and free of damage in mind. It resists moisture, puncturing, tearing, and more. The material is stronger than most other options for sending documents, photos, papers, etc. 

  • The envelope must be able to close without modifying the package.
  • Tyvek Envelopes are not padded.

Tyvek envelopes can be ordered from USPS.com in packs of 10 for free. Check the product page for USPS Tyvek envelopes to learn more about them.
