Advantages of 2 Piece DRD Cans in the Packaging and Transportation Process

Structural Stability Resulting from Seamless Forming

Two-piece Draw and Redraw (DRD) cans are produced from a single piece of metal sheet, allowing the body to be formed without a side seam. This seamless structure provides consistent strength throughout the container and reduces potential weak points that might occur in multi-piece cans. Zhoushan Sinda Machinery Co., Ltd., located in Zhoushan—the major manufacturing hub for metal packaging machinery in China—develops advanced 2-piece DRD Can Lines that enhance the stability of the formed cans. The consistent wall thickness and integrated base improve the can’s ability to handle internal pressure, vibration, and stacking loads during packaging and transportation. Because the material distribution is controlled precisely during the draw and redraw stages, manufacturers obtain cans suited for demanding supply chains.

Improved Leakage Prevention During Storage and Transit

One of the critical advantages of the 2-piece DRD structure is the reduction of areas that could potentially lead to leaks. In traditional three-piece cans, the side seam may require additional sealing, whereas DRD cans eliminate this concern by forming the container body from a single piece. This characteristic is especially important for products that undergo sterilization, filling under pressure, or long-distance transportation. Zhoushan Sinda Machinery Co., Ltd. integrates high-precision trimming, coating, and cleaning operations into its DRD production lines, ensuring that the inner surface remains suitable for food, chemical, and aerosol applications. With fewer structural connections, the finished cans maintain product integrity more consistently throughout storage and shipment.

Resistance to Deformation Under Mechanical Stress

In both packaging facilities and transportation environments, metal containers are frequently exposed to impact forces, vibrations, and stacking loads. The single-piece structure and uniform wall thickness of DRD cans offer improved resistance to deformation, which helps maintain shape during filling, labeling, palletizing, and transport. This is particularly important for automated systems where stable dimensions support smooth performance on conveyors and filling lines. The advanced forming systems developed by Zhoushan Sinda Machinery Co., Ltd. help achieve dimensional accuracy during the draw and redraw stages. As a result, DRD cans remain compatible with high-speed application requirements and maintain structural integrity during transit.
