Custom Kraft Corrugated Boxes Built for Protection and Brand Impact
When your product needs more than a folding carton, custom kraft corrugated boxes deliver the structural strength to get orders to customers intact. At Teal Packaging, we produce branded corrugated kraft shipping boxes that combine durability with a clean, natural aesthetic. With a minimum order of 50 units, free design support, and free shipping to the US, Canada, UK, and Australia, we make it easy for e-commerce brands, subscription services, and product companies to order corrugated packaging that reflects their identity from the outside in. Our standard lead time is two weeks, so you can plan your inventory with confidence.
Corrugated kraft packaging has become the standard for direct-to-consumer shipping because it balances cost, weight, printability, and protection better than almost any alternative. When you add custom printing to that foundation, every box becomes a brand touchpoint the moment it arrives at your customer's door.
Materials and Flute Specifications
Our custom kraft corrugated boxes are manufactured using FSC-certified kraft linerboard paired with a fluted medium core. The flute type and wall construction determine the strength and weight capacity of the finished box:
- B-flute (3mm): A compact flute offering good crush resistance and a smooth surface for high-quality printing. Well suited for retail-ready corrugated display boxes and lightweight product shipping.
- C-flute (4mm): The most widely used flute type in e-commerce. Offers a balance of stacking strength, cushioning, and printability. Recommended for most direct-to-consumer shipping applications.
- E-flute (1.5mm): An ultra-thin flute that folds almost as crisply as paperboard. Ideal for small, premium product packaging where a refined appearance is as important as protection.
- BC double-wall (7mm): Combines B and C flutes for maximum strength. Used for heavy products, fragile items, or multi-product bundles that need extra cushioning.
All corrugated stock is printed using soy-based inks for color fidelity and reduced environmental impact. The natural kraft surface brings warmth to any printed design, whether you are going for minimal and modern or bold and colorful.
Customization Options
Branded kraft corrugated shipping boxes can be customized at multiple levels depending on your brand requirements and budget:
- Exterior printing: Full-color flexographic or digital printing on all outer panels. Interior printing available for an added unboxing surprise.
- Box styles: Regular slotted carton (RSC), full overlap slotted, die-cut mailer, wraparound, and custom structural designs.
- Perforations and tear strips: Easy-open features that improve the customer unboxing experience without damaging the product inside.
- Custom inserts: Corrugated dividers, trays, and fit-to-product inserts that hold items securely during transit.
- Coatings: Water-resistant coatings are available for products that may be exposed to moisture during shipping.
Our free design support team handles everything from dieline creation to full artwork development. If you already have brand assets, we will build the layout. If you need design work from scratch, our team will develop options for your review.
Brands looking for a lighter-weight shipping solution may also want to compare our custom mailer boxes, which use a rigid paperboard construction better suited to lighter items.

Sustainability
Corrugated kraft is one of the most recycled packaging materials in the world. Our custom kraft corrugated boxes are built on that foundation with additional sustainability commitments: For related packaging needs, explore our food packaging.
- FSC-certified linerboard: Sourced from responsibly managed forests with verified chain of custody.
- Soy-based inks: Reduced VOC emissions and easier recycling due to improved de-inkability compared to petroleum-based inks.
- High recycled content options: We offer linerboard with significant post-consumer recycled fiber content for brands with aggressive sustainability targets.
- Recyclable and compostable: Uncoated corrugated kraft is curbside recyclable and industrially compostable in most markets.
For brands building a complete eco-aligned packaging range, our kraft boxes collection and our custom subscription boxes offer matching kraft material options for both retail and recurring shipment formats.
