Can you put stamps on a poly mailer

Yes, you can put stamps on a poly mailer, but it's not always the most effective or recommended way to mail your items. Here's why:

  1. Stamps may not adhere well: Poly mailers are made of a smooth, non-porous material that can make it difficult for stamps to adhere properly. This can lead to stamps falling off during transit or not being recognized by postal machines.
  2. Stamps may not be visible: The smooth surface of poly mailers can also make it hard for postal workers to see the stamps, which can cause delays or issues with delivery.
  3. Weight and size limitations: Poly mailers are designed to be lightweight and flexible, which means they may not be suitable for heavier or larger items that require additional postage.

Instead of using stamps, you can consider the following alternatives:

  1. Use a postage label: You can print a postage label using a printer and a postage service like USPS Click-N-Ship, FedEx, or UPS. This will ensure that your package is properly addressed and has the correct postage.
  2. Use a shipping label: Many online retailers and shipping companies offer pre-paid shipping labels that you can print and attach to your poly mailer. These labels often include the shipping cost and any necessary customs forms.
  3. Use a franking machine: If you're shipping a large volume of packages, you may want to consider investing in a franking machine. These machines can print postage and shipping labels directly onto your poly mailer.

Remember to always check with your local post office or shipping carrier for specific guidelines on mailing poly mailers and any additional requirements for your specific package.
