Heavy Duty Double Wall Corrugated Boxes

Double wall corrugated board typically measures between 7mm and 9mm thick, depending on the flute combination used (such as B-C or A-C flute pairings). This thickness gives the board greater rigidity and cushioning compared to single-wall board, which usually ranges from 3mm to 5mm.

Double wall boxes are corrugated containers constructed with two fluted layers and three flat liner sheets, creating a five-layer board structure. This construction provides significantly higher compression strength and puncture resistance than standard single-wall boxes, making them ideal for heavy, fragile, or high-value goods during shipping and storage.

Depending on box dimensions, flute profile, and board grade, heavy duty double wall boxes commonly support 65 to 275 pounds or more. Manufacturers specify maximum load capacity using edge crush test (ECT) and burst strength ratings, so it's important to confirm specifications for your specific product weight and shipping conditions.

Yes, double wall corrugated boxes can be produced with digital, flexo, or offset printing to display branding, product information, or shipping instructions. Print method selection typically depends on order volume, color complexity, and turnaround time, with digital printing well suited for smaller runs and offset for high-volume branded packaging.

Double wall corrugated boxes are available in a wide range of sizes, from small mailer-style boxes to jumbo industrial containers. Custom sizing is also common, allowing brands to match box dimensions precisely to their products, reduce void fill, and optimize shipping costs and space utilization.

Yes, double wall corrugated boxes are made from paper fiber and are widely accepted in curbside and commercial recycling programs across the United States. Many manufacturers also produce these boxes using recycled content, further supporting sustainable packaging goals without sacrificing structural strength or protection.
