Frequently Asked Questions

What are EcoX mailers?

EcoX mailers are water-resistant, plastic-free paper mailers made from 100% recycled kraft paper. They’re designed as a more sustainable alternative to traditional poly mailers, offering strong protection for soft goods while remaining curbside recyclable.

Are EcoX mailers waterproof?

No, EcoX mailers are water-resistant, not waterproof. That means they’re designed to protect your products against light rain, splashes of water, or damp transit conditions, but they aren’t fully sealed against prolonged exposure or full submersion.

Can EcoX mailers be reused if they get wet?

Yes, if an EcoX mailer gets wet but isn’t damaged, it can still be reused. The material, despite being made of recycled content, holds up well to moisture. We recommend letting it dry before reusing it.

How do EcoX mailers compare to plastic waterproof mailers?

Traditional waterproof mailers are typically made from polyethylene or synthetic materials. EcoX mailers provide similar protection for most eCommerce shipments but are plastic-free, recyclable, and made from recycled paper, making them a lower-impact option for eco-conscious brands.

How do EcoX mailers differ from Kraft mailers?

While both are made from recycled content and are curbside recyclable, EcoX mailers offer added durability and water resistance. This makes the EcoX ideal for apparel and other goods that need a bit more protection in transit.

Are EcoX mailers a good eco-friendly mailer option for apparel?

Yes. EcoX mailers are especially well-suited for shipping apparel, textiles, and other soft goods that need moisture protection without rigid structure. They’re a popular choice for brands transitioning away from plastic mailers.

If I want a plastic-free poly mailer, is the EcoX a good option for me?

When going plastic-free, we recommend using mailers made of natural fibers over compostable bioplastics, which aren't ideal for eCommerce. Learn more here and here.

We also encourage you to choose 100% recycled paper packaging whenever possible.

A common misconception is that going from plastic to paper is always a great transition and that all paper is good. Unfortunately, much of today’s paper comes from ancient and endangered forests, and brands transitioning to paper must be thoughtful about where their paper is sourced.

With our paper hierarchy and framework, we believe that 100% recycled, paper-based packaging with high post-consumer waste levels is a great alternative to plastic poly mailers. EcoEnclose offers many options that satisfy those criteria, three of which are great solutions for apparel companies: the Apparel Mailer, the Kraft Mailer, and the EcoX Mailer.

What are the differences between EcoEnclose's suite of paper mailers?

In general, we consider our Kraft Mailer to be our economy option. It is the least expensive, thinnest paper mailer we offer, and has 90% or more post-consumer waste. In general, we tell companies that if the Kraft mailer already works for them, they can stick with it—it's a great plastic-free mailer.

Our EcoX Mailer is our value option. It is thicker than the Kraft Mailer (11 pt versus 10 pt) and has only 70% post-consumer waste. The remaining 30% is post-industrial, which has stronger and cleaner fibers, giving the mailer a higher level of strength. It’s an excellent choice for companies that need stronger packaging, and/or want a little extra water protection.

Our Apparel Mailer is our premium option. It is the most expensive of the three, but utilizes the thickest paperboard of them all, and has top and bottom creasing for expandability and a clean finish.

All three are 100% recycled, curbside recyclable, and naturally biodegradable.

What paper mailer does EcoEnclose recommend?

All of our paper mailers are made with recycled content and are curbside recyclable, making them a great option for brands pursuing a plastic-free packaging strategy. Each mailer offers reliable performance, so you can choose the best fit based on your sizing and shipping needs, knowing that every option is both effective and eco-friendly.

Are plastic or paper mailers more eco-friendly?

100% recycled plastic mailers options have a lower carbon footprint, offer more protection, and come at a lower overall cost than 100% recycled paper alternatives. However, because they’re made of thin film, they typically need to be recycled at grocery store drop-off bins, which can make recycling more complicated for the average household.

100% recycled paper mailers are curbside recyclable. However, paper mailers have a higher carbon footprint, are more expensive, and more space-intensive to ship and store.
