USPS Bubble Mailer Shipping Rules

• Maximum weight: 70 pounds and maximum combined length + girth: 130 inches.
  
  

• For large envelopes (“flats”), mailpieces must be flexible. Items thicker than ¾″ or weighing more than 13 oz may be treated as parcels, which typically cost more.
  
  

• Mailpieces must fit within size and flexibility guidelines for large envelopes. The bubble mailer will get classified as a parcel if it becomes too thick or rigid which leads to higher shipping costs.
  
  

• Make sure your mailpiece is the correct size in order to avoid extra charges. The thicker or more rigid the item is, the greater the chance it will be considered a package instead of an envelope.

USPS Padded Envelope Shipping Rules

• USPS‑supplied padded flat-rate envelope packaging must be used as intended, i.e., Priority or Express mail services. The cost and weight limits for these containers are fixed.
  
  

• For non‑flat-rate padded envelopes, ensure they meet the requirements for being classified as a flat or large envelope. Otherwise, your package may be treated as a parcel.
  
  

• Proper sealing and correct size packaging can help avoid surcharges. Packaging that’s not correctly sealed may delay processing or increase shipping costs.
