Frequently Asked Questions

What is a rigid mailer?

A rigid mailer is a paper mailing envelope designed to ship items such as artwork, documents, and prints that should not bend in transit. These mailers range in paperboard thickness (20 to 40 pt) and closing structure (tab-locking or self-sealing). Their paper construction makes them more susceptible to the elements, unlike plastic mailers such as poly mailers.

What is the difference between self-sealing and tab-locking rigid mailers?

The primary difference between our to rigid mailers is in paperboard thickness. Our self-sealing rigid mailer is made with 28 pt paperboard, making it strong and durable. However, our tab-locking rigid mailer is more sturdy, made with a 36 pt board.

Our self-sealing rigid mailer has an adhesive strip on the closing flap. This closure means no shipping tape is required to secure them closed. On the other hand, the tab-locking mailer is so thick that it cannot be closed with a self-seal. Therefore, the closure on our tab-locking mailer uses notches which most brands seal with packing tape.

Additionally, our largest self-sealing mailer is 11x13.5”, while our largest tab-locking mailer is 12.75x15”. The two smaller sizes in each mailer are the same.

What products ship well in rigid mailers?

Our rigid mailers are an excellent solution for shipping prints, postcards, photos, very thin books, thin framed art, etc. Self-sealing rigid mailers are also used for shipping flat, thin products, such as wallets. Rigid mailers are also excellent for sending important documents you don’t want to be bent during transit.

It is important to note that these mailers are made with uncoated paper. If paper fibers mustn't touch your product, we recommend adding a layer of protection between your product and the mailer - such as a glassine bag, tissue paper, or a clear poly bag.

Are EcoEnclose rigid mailers FDA-Compliant?

Yes - our rigid mailers are FDA-Compliant, meaning the product is compliant with FDA rules and regulations and is created with materials that are FDA-Approved. We recommend ordering case quantities if you plan to use these for direct food contact because our bundles are re-cased in a non-FDA compliant facility.
