2. Full Product Description

Nanjing Shengjiang Packaging Co., Ltd. manufactures square cardboard drums (also known as square fiber drums) engineered for manufacturers and distributors who want maximum efficiency without compromising protection.

Unlike traditional round containers, our square drums pack flush against one another on a pallet and inside a shipping container. The result is higher cube utilization, lower freight cost per unit, and tidier warehouses. Each drum is built from high-density kraft fiberboard with reinforced top and bottom closures, giving it the strength to withstand stacking loads and the rough handling of modern supply chains.

A moisture-resistant inner liner and sealed construction keep humidity, condensation, and spills away from sensitive contents—making the drums ideal for powders, granules, food ingredients, chemicals, and more. For regulated cargo, we offer UN-certified configurations suitable for the packaging of hazardous (dangerous) goods, compliant with international transport requirements.

Whatever your product, our team can supply square cardboard drums in a full range of sizes and capacities to match your filling line, storage layout, and shipping pattern.
