Can i seal priority mail boxes with duct tape

The age-old question!

While it might seem like a good idea to seal Priority Mail boxes with duct tape, it's not the best approach for several reasons:

  1. Voiding the USPS guarantee: The United States Postal Service (USPS) has specific guidelines for sealing Priority Mail boxes. Using duct tape to seal the box may void the USPS guarantee, which means you may not be able to file a claim if your package is lost, damaged, or delayed.
  2. Damage to the box: Duct tape can damage the box's adhesive or cause it to tear, which can lead to the box opening during transit. This can result in your package being damaged or lost.
  3. Difficulty in opening: Duct tape can make it difficult or impossible to open the box without damaging it. This can cause delays and inconvenience when the recipient needs to access the contents.
  4. Inconsistent sealing: Duct tape may not provide a consistent seal, which can lead to air leaks or moisture entering the box. This can cause damage to the contents or compromise the package's integrity.

Instead, you can use the following methods to seal Priority Mail boxes:

  1. Use the provided adhesive: Priority Mail boxes come with a pre-applied adhesive strip on the flap. Make sure to apply the flap correctly to ensure a secure seal.
  2. Use packing tape: Packing tape is specifically designed for sealing boxes and is a better option than duct tape. It's easy to apply, provides a consistent seal, and won't damage the box.
  3. Use a sealing tape: USPS offers a sealing tape specifically designed for Priority Mail boxes. This tape is designed to provide a secure seal while allowing for easy opening.

Remember to always follow the USPS guidelines for sealing Priority Mail boxes to ensure your package is properly sealed and protected during transit.
