ReEnclose Mailers In Action

We've designed the ReEnclose Mailer to be easy to use.



Partner With Us

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.

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.

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.
