Profile: F P Cartons Ltd. is a supplier of the computer paper trade with boxes. Our boxes are designed for computer paper, and are used in a number of applications. When erected, they have a flat bottom. So, the paper when left in the box does not develop a memory ripple. We also print, cut, and glue most grades of corrugated board from e-flute all the way through to heavy grade twin-wall, in brown, white, or oyster.
