Plastic wrap does not provide any protection to the bottom of the package so the bottom ream gets damaged in normal handeling. Especially the corners. Figure on throwing away 100 sheets from the bottom ream.
The paper was damaged in one of the corners so when we used it in our copy machine it caused a misfeed. We hope that Staples will be able to review their products before stocking the shelves.
Many sheets of paper in each ream are wrinkled/creased. Since the paper wrapping on each ream is similar to other brands of paper I can only assume that the wrinkling was caused by either the manufacturing process or by the plastic wrap used to package the 5 reams.
