Keep Your Products Secured During Shipment With Our Corrugated Packaging Supplies.Strengthen your shipments quickly and easily in our chipboard boxes. Chipboard, which is also known as paperboard, is a thick cardboard-like material made from the compression of paper fibers. When used for shipping purposes, the chipboard is most often a support material, the backbone of any shipment. Larger pieces are used instead of corrugated pads on pallets, while smaller pieces are used to stiffen mailer envelopes. And while it’s not used as shipping boxes, it’s made into folding cartons for smaller items, gifts, and clothing.
