Branded Mailers

"Mailers" isn't one product — it's a family of formats, and each suits a different job:

• Rigid mailers hold their shape without folding, giving flat goods (documents, prints, thin electronics) crush resistance without the bulk of a full box.
• Padded and poly mailers wrap the product in a lightweight, water-resistant shell — poly film outside, bubble or foam cushioning inside — built for apparel, small accessories, and anything that doesn't need a rigid form to survive transit.
• Mailer envelopes are the flattest option: paperboard or poly envelopes for catalogs, inserts, and direct mail pieces where postage weight matters more than cushioning.

Picking the right format starts with what's inside: fragile and rigid goods want structure, soft goods want flexibility, and flat print pieces mainly need protection from moisture and bent corners.

Poly and padded formats carry most of the volume in a branded mailer program, and the two get specified differently.

Custom Poly Mailer Bags

A poly mailer bag is a single-layer film envelope with a self-seal strip — the lightest way to move soft goods through a parcel network. Because the film prints edge to edge, custom poly mailers give you the largest branded surface of any format on this page. We run them plain, in a single spot color, or in full-coverage print with your logo repeating across the face, and we hold that brand color across reorders so the tenth run matches the first. Wholesale-volume orders run flexographic; short runs and seasonal artwork run digital.

Custom Bubble Mailers

A bubble mailer adds an air-cell or foam liner between the film and the product, which is what you want once an item can dent, scratch, or crack. Branded bubble mailers print on the same outer film as a plain poly mailer, so you aren't trading branding for cushioning. A foam mailer liner does the same job with a denser, quieter fill for finishes that mark easily. Which one a product needs usually comes down to a prototype — we sample both and let the product decide.

Mailers and mailer boxes solve overlapping problems but aren't interchangeable. A mailer is generally a single-layer, film- or paperboard-based format that flexes with its contents; a mailer box is a rigid, self-locking corrugated structure built to stack, ship without an outer carton, and protect heavier or higher-value goods. If your product needs a hard shell and a tamper-evident closure rather than a flexible wrap, our custom mailer boxes are the better fit — many of our e-commerce clients run both formats side by side, using mailers for lightweight items and mailer boxes for anything that needs to survive a conveyor belt.

Material choice is where branded mailers earn — or lose — sustainability points. Standard poly mailers are lightweight and water-resistant, but eco-friendly poly mailers swap in recycled or post-consumer content, and biodegradable films break down without leaving landfill plastic behind. Cardboard and paperboard mailers remain the most recyclable route for brands that want curbside-friendly packaging without sacrificing print quality. Recyclable poly mailers sit between the two — still film, but specified to go back into a film-recycling stream rather than the curbside bin. We help clients weigh these options against cost and durability, and our eco-friendly mailers guide walks through the material tradeoffs in more detail.

Every branded mailer is a marketing surface. We print full-color logos, interior messaging, and color-matched films or coatings directly onto rigid, padded, and poly formats — flexographic runs for volume orders, digital printing when you need short runs or per-order personalization. Because prototyping and print happen as one connected process, you see a physical sample before committing to a production run, not just a rendering on a screen. Personalized mailers built this way tend to perform better in unboxing photos and repeat-purchase campaigns, since the branding is consistent from the first order to the thousandth.

Branded mailers are the backbone of most e-commerce packaging programs — apparel, cosmetics, and accessories brands lean on padded and poly formats to keep shipping costs down while making unboxing feel intentional. Every industry ships something different, and mailer packaging specs should flow from what's inside: cosmetics need padded protection, apparel needs a light poly film, and outdoor gear needs abrasion resistance. We craft sports equipment packaging to match. Whatever the vertical, our ecommerce packaging programs scale from small-batch launches to full production runs, with the same team handling design, prototyping, and print at every stage.

Custom Mailers for Small Business

Small runs are where most brands get told no. Digital printing changes that math: because we can put a short run on digital, custom mailers for a small business launch can carry the same full-color branding as a volume order, just without the flexo plate setup in front of it. Send the artwork and the quantity you actually need, and we'll tell you which print method makes sense at that size rather than quoting you into a run you can't sell through.

What's the difference between a mailer and a mailer box? A mailer is a flexible, single-layer format — poly, padded, or paperboard — that shapes itself around the product; a mailer box is a rigid corrugated structure that holds its own form and ships without an outer carton. Fragile or heavier items usually call for a mailer box, while lightweight, flexible goods do fine in a mailer.

Are eco-friendly poly mailers as durable as standard poly mailers? Recycled-content and biodegradable poly films perform very similarly to virgin poly in tear and water resistance — the tradeoffs show up more in cost and lead time than in on-shelf durability. We can run samples of both so you can compare before committing to a production order.

Can you print small quantities of branded mailers? Yes. Digital printing lets us produce short runs with full-color branding and even per-order personalization, while flexographic printing is more cost-effective once you're ordering in volume. Tell us your order size and timeline and we'll recommend the right method.

Can you match our brand color on a poly mailer? Yes — we color-match films and coatings against an approved proof and hold that standard across reorders, so a repeat run doesn't drift from the original. For full-coverage artwork we'll proof a physical sample first, since a color reads differently on poly film than it does on paperboard.
