What are poly mailers?
Their self-sealing adhesive closure means no shipping tape is required to secure them closed, and because they do not take up as much space or weight as traditional shipping boxes, they are very cost-effective to ship and store.

What size poly mailer bag do I need and what poly mailer sizes are available?
Once you have what you think is the perfect-sized mailer, try free samples to test those you are considering. One of the worst feelings in the world is gathering everything you need to start shipping and discovering that what you thought was perfect is too small to use. We encourage testing samples to avoid shipping issues.
As a frame of reference, we’ve assembled a table of everyday items shipped in our mailers.

EcoEnclose offers 8 mailer sizes:
- 6 x 9”
- 7.5 x 10.5”
- 9 x 12”
- 10 x 13”
- 12 x 15.5”
- 14 x 19”
- 19 x 24”
- 24 x 24”
Do poly mailers come with a strip to seal them? Are they reusable?
Ours feature two seals and an easy-to-use tear strip, allowing them to be neatly opened and then reused with the second seals for returns, another shipment, or to send poly film back to EcoEnclose for recycling.
A reusable mailer is more sustainable and can help you build a seamless return experience. While we all hate returns, we also know that customers are far more likely to shop with you again if you’ve made their returns process as convenient as possible.
We have you covered if you want a tough, reusable mailer. Check out our ReEnclose Mailer, designed to be used 50 or more times, a great solution for apparel subscription companies and those who have baked a return shipment into their business model.

Can poly mailers protect fragile items?
Are poly mailers suitable for shipping clothes?
Can large poly mailers be used for bulky items?
Our largest offerings are 14” x 19”, 19” x 24”, and 24” x 24", and they are suitable for large or bulky shipments.
Is it cheaper to ship poly mailers or boxes?
If you are trying to choose the most eco-friendly and cost-efficient option, we highly recommend our 100% recycled poly mailers as long as they work well for your shipments.
When it comes to small businesses, which option is more suitable - poly mailers or shipping boxes?
Are white poly mailers available?
We also offer gray. The only difference between our ivory and gray is the color of the mailer and the available sizes. They share the same quality recycled content and other eco-features and technical specs.
Can I customize poly mailers?
For e-commerce companies, the shipped package represents the most direct touch point with a customer. Customization creates a solid first impression and encourages loyalty and repeat sales. Not to mention, 83 percent of consumers would share an image of a delivery via social media if it arrived with unique branding. So branding your mailer is an effective way to not only build loyalty, but it can also drive new sales.
Unlike many companies that require you to order 5,000 or more to get a basic print, we offer custom mailers for as low as one case. Find your desired mailer in the grid above and click “Customize Now.”
Some important things to keep in mind when thinking about customization:
- Prints are limited to one color
- Artwork must remain within the artwork boundary
- Artwork must be in vector format
- Read our complete list of artwork guidelines before placing your order
Our printing capabilities greatly expand if you are interested in runs of at least 25,000 mailers. For more information on these options, submit a high-volume quote.
Can I print with Algae Ink?
We have made algae ink available for corrugated boxes and paper-based solutions since 2018. In early 2022, we launched this technology for poly. If you’re interested in using algae ink for your next poly print with black ink, contact us at hello@ecoenclose.com.

What do you mean by functional resin and recycled content?
The functional resin in our mailers is made with 100% recycled content, at least 50% of which is post-consumer waste. The colorants, additives, release liners, and adhesives are not made with recycled content. This is true for our mailers and all other mailers available today. We see these as important opportunities for improvement.
