Which custom poly mailer is best?

Many companies and organizations that ship goods frequently will swear by custom poly mailers, primarily offering one last chance to help customers remember your brand. And while the mailer component of these products is fairly straightforward, finding a custom poly mailer that represents your organizational identity is key, and may take a little bit of searching.

For brands that are considerate of the environment, this 50-Pack of KTOB 10×13-Inch Biodegradable Poly Mailers is a great way to show your customers and clients that passion and have a reduced impact on the environment in the long run.

What to know before you buy custom poly mailers


Choosing the best bubble mailers and custom poly mailers for your needs is the first factor to consider when choosing which set to purchase. For example, if you need something with a specific visual identity, you’ll likely find a variety of custom poly mailers to suit that vision — or you can at least have your own customized mailers made.

Bubble poly mailers vs. non-padded mailers

Depending on the items you plan to send, it’s worth considering whether you need bubble poly mailers with padding, or if you just need the protective envelope bag to get your items from one place to another. Those buying non-padded mailers can also supply their own padding, making those just a little bit more versatile, despite being a little more work.

Custom poly mailer designs

Some search for custom poly mailer designs featuring their organization’s logo or copy, while others may simply want an affordable, pre-made design that scratches the same itch. Custom poly mailers can be found in a wide range of styles, colors and overall aesthetics, so deciding what you want may help you narrow down your mailer options.

What to look for in quality custom poly mailers

Appropriately sized

You’ll need your items to fit into your mailer, so finding custom poly mailers that are appropriately sized is crucial. Mailers tend to come in one of a handful of different standard sizes ranging from 4- by 8-inch to 14.5- by 19-inch, though you can also find a number of custom-size poly mailers.


Any good mailing envelope or bag needs to be completely sealed using the attached adhesive strip. Custom poly mailers that aren’t well-sealed risk exposing shipped items to the outside atmosphere, or being ripped open entirely while in transit.


Part of the appeal in buying custom poly mailers is choosing a design that suits your style or brand. A stylish, custom poly mailer can leave a lasting impact and a good first impression when customers or clients receive their deliveries in the mail.

How much you can expect to spend on custom poly mailers

For customized poly mailers with your own design, you can expect to pay more than the custom poly mailers you’ll find with designs on them already through many online retailers. Usually, a set of cheap custom poly mailers can cost as little as $9, though most designer and larger packs of custom poly mailers will run you between $15-$50.
