When you’re shipping day in and day out, packaging can feel like a constant tug-of-war: keep costs in check, protect what’s inside, and still do right by the environment. That’s exactly where Eco-Natural Lite® paper mailers shine – a lightweight, cost-friendly option that doesn’t ask you to compromise on your sustainability goals.
Made for busy fulfillment teams, growing e-commerce brands, and the distributors who support them, Eco-Natural Lite® gives you an easy way to ship smarter while keeping your customers (and the planet) in mind.
💪 Built from one clean sheet – for a cleaner, stronger mailer

Eco-Natural Lite® mailers are crafted from a single, uncut sheet of 100% recycled paper, which helps create a smooth, dependable structure without extra material or unnecessary complexity. That design also features a seamless lip – a simple detail that delivers two big wins:
- Extra strength where it counts
- A clean, polished look your customers notice when it arrives at the door
And because shipments aren’t always one-size-fits-all, Eco-Natural Lite® mailers have a flexible gusseted design that can handle a variety of content sizes.

📐 Available sizes for Eco-Natural Lite® mailers
One of the nicest parts about Eco-Natural Lite® is how easy it is to match the mailer to the job – so you’re not paying to ship extra air, and your customer isn’t wrestling with an oversized package.
Here are the current Eco-Natural Lite® size options (custom sizing available):
- 10G – 10 1/2 x 3 3/4 x 19
- 12G – 12 1/2 x 4 x 20
- 18G – 18 1/2 x 6 1/4 x 24 3/4
A quick rule of thumb: the 10G is a great everyday go-to for smaller, flexible items; 12G gives you a bit more room for thicker packs; and 18G is the workhorse when you need extra capacity for bulkier soft goods.

🌱 Sustainability that’s easy to explain (and easy to feel good about)
If you’re looking for a mailer that supports a true sustainability story, Eco-Natural Lite® checks the boxes:
- 100% recycled content with 90% post-consumer fibers
- 100% curbside recyclable
- Biodegradable and compostable
That means your end users aren’t stuck with a pile of plastic packaging after every delivery – and you’re not stuck trying to justify it. It’s a simple switch that helps reduce packaging waste and aligns with what today’s shoppers increasingly expect.
✅ Fast packing, reliable sealing
On the production floor or at a packing station, speed matters. Eco-Natural Lite® comes standard with a Peel & Seal adhesive strip, making it quick to close up and get moving – no extra tape, no fuss, no training curve.
For distributors and brands shipping at scale, those small time savings add up fast.
🔁 Returns + resendable closures: reducing hassle
Returns are part of the real world – especially in e-commerce. The question is: does your packaging make returns easier or harder?
With Eco-Natural Lite®, you can choose a resendable closure option designed specifically to reduce headaches and keep the process tidy. That includes:
- A perforated quick-open tear strip for clean, easy opening
- An additional re-seal adhesive strip so customers can close it back up for a return or reuse
This is one of those features that quietly improves the whole experience:
- Fewer customer complaints (“I had to destroy the package to open it.”)
- Less need for extra return materials
- A more sustainable returns process, since one mailer can do more than one job
In short: it makes returns feel less like a hassle and more like a built-in part of a thoughtful packaging system.

🖨️ Make it yours with custom printing
Eco-Natural Lite® mailers can be custom printed with your logo, return address, or promotional messaging – helping distributors and end brands build recognition while clearly communicating sustainability values right on the package.
When a customer holds the mailer in their hands, your brand message is already there – no extra insert required. Custom printing options include Flexographic Printing, Post-Printing, Hot-Stamping, and Digital Printing.
💡 A smart fit for businesses of all sizes
Eco-Natural Lite® works perfectly for:
- Large e-commerce operations and distribution centers
- Subscription box brands
- Smaller shippers and makers (including Etsy-style businesses)
- Any business looking for a cost-friendly paper mailer that still feels premium
If you’re helping customers move away from plastic mailers, Eco-Natural Lite® is a strong, practical next step.
