Corrugated cardboard mailer boxes combine fluted corrugated board with reinforced wall construction, built for wholesale buyers who need more crush resistance and stacking strength than a standard single-wall mailer offers. The compound name describes the material itself: true corrugated cardboard has a wavy fluted layer glued between two flat liner sheets, not the flat solid board used in lightweight folding cartons. Crat Packaging manufactures corrugated cardboard mailer boxes at its own US facility, with double-wall options for heavy or fragile shipments, full-color printing, and MOQs starting at 100 units.
Why Choose Our Corrugated Cardboard Mailer Boxes
- True corrugated construction — a fluted medium bonded between liner sheets gives real crush and stacking resistance, unlike flat chipboard or paperboard mailers.
- Double-wall option for heavy loads — two fluted layers combined for extra-fragile or heavy products that exceed what single-wall corrugated cardboard can safely handle.
- Higher ECT ratings on request — we can spec board strength (edge crush test) to match your product weight and the distance it needs to travel.
- Self-locking, tape-free assembly — tuck-style and roll-end closures fold shut without tape, cutting pack-out time on the warehouse floor.
- Full CMYK printing inside and out — unlimited colors at no extra charge, plus matte or gloss lamination, spot UV, and foil stamping.
- US-sourced, recyclable board — corrugated cardboard produced domestically and fully recyclable after use.
- Custom inserts and dividers — corrugated or foam inserts keep multiple items, glass, or ceramics from shifting inside the reinforced shell.

Customization Options
Single-Wall vs. Double-Wall Corrugated Cardboard
Single-wall corrugated cardboard mailer boxes use one fluted layer and handle most e-commerce and retail shipments efficiently. Double-wall construction adds a second fluted layer for products that need real impact protection — glassware, electronics, industrial parts, or anything shipping through multiple sorting hubs where a box gets stacked, dropped, or compressed under pallet weight.
Flute Selection
E-flute (about 1/16″ thick) keeps the box compact and gives the sharpest print surface for lighter items. B-flute (about 1/8″ thick) trades some print detail for meaningfully more crush resistance on heavier or bulkier products. We help you match flute and wall count to your actual product weight rather than guessing.
Sizes
Boxes are die-cut to your exact product footprint instead of a fixed size chart, so you’re not paying to ship excess air or risking a product shifting inside an oversized box.
Printing & Finishing
Full CMYK printing covers the box inside and out at no added color cost, with PMS spot color matching available for exact brand-color consistency. Matte or gloss lamination, spot UV, foil stamping, and embossing/debossing all add a premium finish on top of the reinforced board.
Inserts & Add-Ons
Corrugated or foam inserts and dividers hold multiple items, glass, or ceramics in fixed positions inside the box, which matters more on double-wall builds carrying heavier or more fragile contents.
Industries & Use Cases
Manufacturers and B2B distributors rely on this reinforced construction for bulk product shipments where stacking strength during warehouse storage matters as much as transit protection. Beauty, food, and beverage brands use double-wall builds to protect glass bottles and jars moving through freight networks. Electronics and hardware companies use the reinforced construction to ship components and parts without secondary outer cartons, while subscription box and gift companies use the added durability for multi-item sets crossing long shipping routes.

Frequently Asked Questions
What does the term “corrugated cardboard” actually mean?
It’s the fluted board itself — a wavy paper medium glued between two flat liner sheets. This term specifically describes that three-layer construction, as opposed to flat solid board used in lightweight cartons that has no fluted layer at all.
When should I choose double-wall over single-wall?
Double-wall corrugated cardboard makes sense for heavier products, glass or ceramic items, or shipments that pass through multiple handling and sorting points where crush resistance matters most. Most standard e-commerce shipments do fine on single-wall.
How much weight can a corrugated cardboard mailer box hold?
It depends on flute type and wall count. Single-wall E-flute typically handles items up to roughly 20–25 lbs, B-flute up to 30–40 lbs, and double-wall builds go higher — tell us your product weight and we’ll spec the right construction.
Is corrugated cardboard recyclable?
Yes. Our corrugated cardboard is US-sourced and fully recyclable, accepted by most curbside recycling programs as standard cardboard.
Can these boxes be printed inside as well as outside?
Yes. Full CMYK printing can cover both the exterior for shipping impact and the interior for a branded reveal when the box opens — mention it at the quote stage so we can price the extra print pass.
What’s the minimum order quantity?
Our minimum order is 100 units with no setup, plate, or die-cut charges added to your quote.
