Five-Panel Folder – FPF
The Five-Panel Folder (FPF) is perfect for shipping very long products. Because the FPF has several thicknesses of material on each end, it has a particular advantage when used for packaging long articles of small diameter which might be readily damaged if forced through the ends of the box.
Five-Panel Folder Center Flap – FPFCF
The Five-Panel Folder Center Flap (FPFCF) is similar to the FPF except the FPFCF is sealed at the center seam on the top. This makes it easier to load products; however, the FPFCF is not quite as strong as the FPF. It is best used for shipping flat items.
