Making the switch to reusables can be complicated. For some business models, reusables is an environmental win. For others, single-use packaging is the more sustainable option. Reusable mailers can make your logistics more complex and costly, or they could be an efficient and less expensive long-term solution.
EcoEnclose will be your EcoAlly, helping you be thoughtful and data-driven in your decision making and providing hands on guidance as you shift your operations towards reusable packaging. We won't push reusables when it isn't the right fit, and we will be a thought partner when you face unexpected logistical challenges. We'll customize your ReEnclose Mailer to achieve a minimal environmental footprint and maximum brand impact. We will test and decide on the best packaging solution for your business model and environmental goals.
Frequently Asked Questions
+ Can I custom size the ReEnclose Mailer?
Yes - Contact us if you need a custom sized ReEnclose Mailer (minimum roder quantitiy 100 units) and read below how our stock mailers can be right-sized.
Right-sizing your packaging ensures cost and shipping rate efficiency, and quality customer experience and sustainability.
Suppose you exchange your existing single-use mailer with a reusable mailer of the same size. In that case, you'll need to ensure reusable packaging is used at least 20-30 times to ensure an equal environmental impact with your single-use mailer. On the other hand, if you replace your existing single-use mailer with a larger reusable mailer than your current single-use mailer, the number of uses of that reusable mailer rises significantly to ensure an equal environmental impact.
We offer four sizes of ReEnclose Mailers, so you can choose the mailer that is best suited to your shipment. Our large and extra-large reusable mailers feature snaps that enable the mailer to be sized down by folding and snapping the mailer into place. This snapping feature is beneficial for the mailer's journey back to your fulfillment center. For example, your customers will likely send back a portion of the items they received if you run a clothing subscription business. With our snapping feature, your customers can size down the reusable mailer to snuggly secure their return products.
+ Can I custom brand the ReEnclose Mailer?
Yes - Create an exceptional customer experience with eco-friendly custom packaging. We offer screen printing services on all of our ReEnclose Mailers so that you can include your brand logo or custom artwork directly on your reusable mailer.

+ What happens at the end-of-life of ReEnclose Mailers?
Reusable packaging is an excellent step towards a more circular future. But, for reusable packaging to be a better solution for the planet, it must be recycled at the end of its useful life. Reusable mailers are typically about 20 times heavier than single-use poly mailers. So, if your reusable mailers end up in the landfill after 20 uses, they will have resulted in more landfill waste than the poly mailers they replaced.
Unfortunately, our recycled polyester fabric ReEnclose Mailers are not curbside recyclable. But don't worry! We'll take care of the recycling process for your brand and customers. Send your reusable mailers to EcoEnclose when they are no longer usable. We have partnered with g2 revolution, which ensures that recycled ReEnclose mailers are shredded, cleaned, and reused in the making of composite decking. g2's services aim to reduce waste generation through reuse, recycling, or recovery of used materials to make new products.
If your brand ships in ReEnclose Mailers, we'll share more detail about how to collect and send back old mailers to our warehouse.
+ Are reusable mailers more sustainable than poly mailers?
Frustratingly, it depends. Consider these critical factors:
- What are the source material and weight of the reusable mailer and the compared standard mailer?
- How many cycles do you anticipate for your reusable mailers? How does this number compare to your standard mailer?
- What happens to your reusable mailer at the end of its useful life? What typically happens to your standard mailer?
- Does your reusable mailer have to be cleaned frequently throughout its useful life?
Typically, a reusable mailer becomes more sustainable than a poly mailer after several uses. However, the number of uses varies based on the above variables. Our analysis shows that reusable mailers need to be used 20-30 times to ensure an equal impact, depending on the two mailers' construction and features.
Use our Reusable Mailers Sustainability Calculator to help estimate how many uses or "cycles" your reusable mailer must go through to ensure it has the equivalent carbon footprint of the poly mailers you are replacing.

Materials
Made from a single ply 100% recycled woven polyester fabric, made from recycled plastic bottles. Treated with an eco-friendly C0 DWR and a water-resistant PU coating. Zippers, snaps, and shipping label cover are made of virgin plastic.
Each yard of fabric recycles about 10 plastic bottles and saves about one pound of carbon emissions, compared to standard nylon or polyester bag fabric.

Weight
Our fabric weights - Medium 400D and Thick 840D - vary in texture, thickness, and aesthetic.
We recommend Medium 400D to reduce the amount of material in each mailer, reducing your carbon footprint. If our medium weight material works for you, we'll push firmly for it as the most environmentally preferred option. We offer Thick 840D because we recognize some brands are seeking a thicker, more premium material.
