Custom Kraft Shipping Boxes
Our kraft shipping boxes are made from corrugated kraft board with E-flute or L-flute layers for real strength. No plastic coating, no lamination — just pure paper fiber built to handle long travel. They fold flat, tape tight, and protect your shipment from the first load to the final doorstep.

Custom Kraft Shipping Boxes Made from Real Corrugated Strength
These boxes are meant to be used, not displayed. Once they’re filled, they get stacked, pushed, and moved around until delivery. Corrugated board handles that pressure better than flat stock and helps stop boxes from caving in. Kraft paper adds strength without making the box heavy. Whether it’s a few orders or a full shipment, the box stays intact and reaches the customer in decent condition.
Why Corrugated Kraft Is Still King
You can tell when a box is real kraft.
The surface feels dry, the walls have that faint ripple when you press them — that’s the flute inside doing the heavy lifting.
It’s not shiny or overbuilt; it’s balanced.
That’s why we use corrugated kraft for every shipping order, whether it’s a single candle or a whole retail batch.
The Flute Makes the Difference
Each shipment has its own stress points — that’s where flute selection matters.
- E-Flute: thin and neat for smaller boxes and branded mailers. It’s light but keeps corners stiff.
- B-Flute: middle ground — works great for bulk or mid-weight goods like jars or food kits.
- L-Flute: thick, steady, and serious. The one we use for heavy or fragile shipments that can’t afford a dent.
All are bonded with natural starch adhesive and lined with high-grade kraft paper — completely recyclable.
Common Weak Spots (and How We Avoid Them)
Most cheap boxes fail at two spots: the corner fold and the tape line.
That’s why we double-crease folds and align fluting with the stress direction.
We don’t use shiny coatings that peel under tape — kraft’s natural surface gives better adhesion.
Every prototype goes through crush and drop testing before print approval.
It’s slow work, but that’s what keeps your shipment square and safe.
No Plastic, No Compromise
Everything we use — liners, glue, and print — is paper-safe.
Adhesives are starch-based, inks are water or soy-based.
No film lamination, no wax, no mixed fibers.
That’s what keeps your boxes fully recyclable in any paper stream.
Finishes That Match Function
We keep printing clean — solid colors, bold logos, or simple product data.
Matte kraft gives natural contrast that doesn’t glare under warehouse lights.
If you need color branding, we print directly on the outer liner — still fully biodegradable.
Simple finish, strong impression.
Testing Like It’s Meant to Travel
We don’t test empty boxes. We load them, stack them, drag them, and tape them until something gives.
That’s how we know the right flute choice before production.
If you’re shipping fragile goods, we’ll pair L-flute strength with reinforced kraft dividers for an all-paper solution — no plastic foam.
Who Uses These Every Day
- E-Commerce brands sending heavy or delicate items.
- Food suppliers moving packaged dry goods or bakery stock.
- Gift brands that want eco packaging strong enough for shipping.
- Industrial clients needing tough boxes without plastic waste.
Every one of them needs something that travels far but still opens neatly when it arrives.
How We Work With You
- You send your product specs or weight range.
- We choose the right flute (E, B, or L) and kraft thickness.
- You receive sample boxes for load testing.
- Once approved, we run production — flat-packed, clean-cut, and ready to tape.
You get one point of contact through it all — no hand-offs, no confusion.
