Custom Rigid Mailers
Crafting packaging excellence, delivering your brand’s success.
Custom Rigid Mailers
Custom Rigid Mailers
Custom Rigid Mailers provide dependable protection for documents, artwork, photographs, certificates, and other flat items during shipping. Made from durable paperboard or fiberboard, they help prevent bending, creasing, and corner damage while keeping shipping lightweight and cost-effective. At Rigid Packaging Boxes, we create custom rigid mailers in your preferred size, style, and finish with premium printing and branding options. Ideal for businesses that need secure, professional, and attractive packaging for important mailings.
Ship Documents and Artwork Without Damage
A bent certificate or a creased print job reflects poorly on your business, even if the content inside is perfect. Rigid mailers solve that problem at the source. Built from sturdy paperboard or fiberboard, they hold their shape through the roughest handling a shipment sees, so what leaves your office arrives the same way.
At Rigid Packaging Boxes, we produce these mailers to your exact dimensions, complete with your branding, and back every order with free design support and a 3–5 business day turnaround. We offer free shipping worldwide, with the USA as our primary market and fastest service area.
Need a different format? Check out our Poly Mailers, Bubble Mailers, and Custom Mailer Boxes for products that don’t need rigid protection.
Why Businesses Choose Rigid Over Flexible Packaging
A standard envelope bends under pressure in transit. A rigid mailer doesn’t. That single difference is why law firms, publishers, and photographers rely on them for anything that can’t afford a crease.
- Structural strength — keeps flat items flat, no matter how the package is stacked or handled
- Light weight — added protection without added shipping cost
- Built to spec — custom sizes and board thicknesses for your exact product
- Full-color branding — printed inside and out to match your identity
- Fast, secure closures — self-seal or tab-lock options speed up packing
- Recyclable material options — for businesses prioritizing sustainable packaging
What Gets Shipped in a Rigid Mailer
If it needs to stay flat, it belongs in one of these. Common categories include:
- Legal & official documents — contracts, certificates, diplomas
- Print & publishing — books, magazines, catalogs, comics
- Visual media — photography prints, art prints, posters, collectible prints
- Marketing materials — brochures, presentation folders, promotional literature
- Everyday paper goods — greeting cards, calendars, vinyl decals
Industries that ship these most often: law firms, universities, photography studios, publishers, marketing agencies, and eCommerce sellers of flat or printed goods.
Choosing the Right Style
Catalog Mailers — open on the short side. Best for catalogs, manuals, and standard document mailings.
Booklet Mailers — open along the long edge. Better suited to presentation folders, magazines, and larger printed pieces.
Self-Sealing Mailers — built-in adhesive strip, no tape needed. Fastest option for high-volume packing.
Tab-Lock Mailers — locking flap closure instead of adhesive. Useful when packaging needs to be reopened or reused.
Materials and Build Options
The right board depends on what’s inside. Lightweight marketing pieces can use a thinner, more economical board; multi-page documents or artwork typically call for something heavier.
| Material | Best Suited For |
| Premium paperboard | Standard documents, marketing materials |
| Heavy-duty cardboard | Multi-page shipments, added rigidity |
| Kraft board | Cost-conscious, eco-leaning orders |
| Corrugated fiberboard | Maximum protection for valuable prints |
| Recyclable paper stock | Sustainability-focused packaging |
Printing and Finishing
Every mailer can carry your branding — full-color CMYK, Pantone color matching, or single/black-ink printing, applied inside, outside, or both.
Finishing options to elevate the presentation:
- Gloss or matte coating
- Soft-touch coating
- Spot UV, foil stamping, embossing, or debossing
Not sure what fits your brand? Our free design support covers layout, color matching, and print-ready file prep at no extra cost.
Sizing
We manufacture both standard and made-to-order dimensions. A snug fit matters more than it seems; extra space inside the mailer means room for contents to shift and corners to get damaged in transit. If your product doesn’t match a standard size, custom sizing is available so you’re not paying for excess material or space.
Rigid Mailers vs. Other Packaging
| Packaging Type | Best For |
| Custom Rigid Mailers | Documents, artwork, photos, certificates, catalogs |
| Poly Mailers | Clothing, textiles, non-fragile goods |
| Bubble Mailers | Small accessories, electronics, items needing cushioning |
| Corrugated Mailer Boxes | Heavier or three-dimensional products |
