The BSC PREFERRED CP8511HD chipboard pads are flat, rigid sheets used as envelope stiffeners and protective inserts in packaging and shipping applications. Constructed from sturdy kraft fibreboard made with recycled paper content, these pads provide a firm surface that resists flexing under normal handling. They are sized for use inside envelopes, mailers, and cartons to keep contents flat and protected. Shipping departments, warehouse staff, and fulfillment operations rely on these pads to reduce damage during transit. Each case contains 470 pads, making them practical for high-volume operations that require consistent protective packaging materials.
These chipboard pads are suited for a wide range of packaging and shipping environments, including distribution centers, mail rooms, and light manufacturing facilities. A primary application is top-layering inside cartons to shield contents from box cutters and knives during receiving. They also serve as envelope stiffeners for documents, photos, and flat goods that must arrive without bending or creasing. The recycled kraft fibreboard construction makes them compatible with standard waste and recycling streams, which is relevant for facilities managing sustainable packaging programs.
The CP8511HD is equivalent to part number S-18997. These pads are designed as general-purpose chipboard inserts for standard envelope stiffening and carton top-layering applications.
No tools or trade licensing are required to use these pads. Insert pads flat against the interior face of envelopes or position them as a top layer inside cartons before sealing. Ensure the pad lies flush with no folding or overlap that would compromise its stiffening function. Store cases in a dry environment to prevent moisture absorption that can reduce rigidity.
