What are custom kraft boxes?
Custom kraft boxes are distinctive commercial packaging containers manufactured from unbleached natural wood pulp that preserves the organic golden-brown hue and long cellulose fibers of virgin timber. Because the pulp bypasses the chemical bleaching process, custom kraft boxes retain superior tensile tear strength, puncture resistance, and environmental appeal compared to standard white paperboard. Kraft packaging spans multiple structural formats including lightweight 16 pt to 24 pt folding cartons for retail goods, heavy-duty 32 ECT E-flute and B-flute corrugated mailers for e-commerce, and wrapped rigid setup boxes for artisanal gifts. While raw unbleached kraft board naturally absorbs liquid ink pigments, commercial converters achieve striking graphic contrast by pairing the earthy brown background with opaque white screen printing, deep monochromatic black inks, or metallic hot foil stamping. Custom kraft boxes deliver authentic sustainability credentials, creating immediate consumer trust for organic skincare, gourmet baked goods, handcrafted soaps, specialty teas, and eco-conscious apparel.
Which structural styles are in the custom kraft boxes group?
Natural kraft substrates adapt across lightweight retail cartons, heavy postal mailers, and rigid presentation boxes. Our custom kraft boxes group brings together four versatile structural packaging styles engineered from unbleached fiberboard

What are common mistakes to avoid when ordering custom kraft boxes?
Designing for uncoated unbleached kraft substrates requires understanding ink absorption and color contrast. Packaging specialists highlight four common errors
- Attempting to print light pastel or yellow CMYK inks directly onto brown kraft board without an opaque white ink understrike base.
- Printing barcodes directly onto raw brown kraft board without a white background knockout, causing automated scanner misreads.
- Creasing kraft paperboard across the fiber grain using shallow scoring rules, leading to jagged cracks along carton fold edges.
- Using thin 14 pt board for heavy jars exceeding 16 ounces, resulting in bulging bottom flaps that buckle under gravitational weight.

What is the minimum order quantity for custom kraft boxes?
Our minimum order quantity for custom printed kraft paperboard folding cartons starts from 500 units. For kraft corrugated mailer boxes, minimums start from 100 units with volume discounts at 1,000, 2,500, and 5,000 units.
Can you print full-color photos on natural brown kraft boxes?
While possible, full-color photographic halftones will shift toward brownish tones due to the natural unbleached background. To preserve true color fidelity, we print an opaque white ink understrike beneath the CMYK image layer.
How does white ink printing work on brown kraft board?
We utilize high-pigment opaque white screen inks or double-hit flexographic white inks. This creates a dense, bright white graphic layer that pops with exceptional contrast against the earthy brown kraft background.
Are custom kraft boxes recyclable in curbside programs?
Yes. Uncoated kraft boxes printed with water-based or soy inks are fully recyclable in standard curbside paper recycling streams, making them one of the most environmentally friendly packaging options available.
What paperboard calipers are available for kraft folding cartons?
We offer virgin kraft folding card in 16 pt (0.016 in), 18 pt (0.018 in), 20 pt (0.020 in), and 24 pt (0.024 in) calipers, allowing you to select the exact rigidity required for your product weight.
Can I add a clear viewing window to a kraft box?
Yes. We can incorporate custom die-cut viewing windows patched with clear PET film or certified recyclable cellulose film, allowing shoppers to view product color and texture directly through the box.
Are there any die cutting or printing plate setup charges?
No. CubitPack never charges separate cutting die fees or printing plate setup charges on custom kraft boxes. All quotes are all-inclusive, including free 2D CAD dielines and digital 3D proofing.
How do kraft folding cartons compare to kraft corrugated mailers?
Kraft folding cartons are crafted from solid paperboard card, ideal for lightweight primary retail packaging. Kraft corrugated mailers feature an internal fluted medium that provides heavy-duty drop protection for postal shipping.
What is the production turnaround time for custom kraft boxes?
Standard production takes 10 to 14 business days following digital prepress proof approval. For urgent retail launches, 4 to 5 business day rush production is available upon request.
Can I order custom paperboard inserts for my kraft boxes?
Yes. We engineer precision die-cut kraft paperboard cradles, partitioned corrugated dividers, and molded pulp trays that hold bottles, jars, and delicate products securely in place without plastic foam.
