Corrugated packaging is not all the same. When you need reliability in every box you need to work with pros like Packsize. Packsize corrugated packaging solutions cover all types of heavy-duty paper that can include card stock, paperboard, and corrugated fiberboard. Corrugated packaging is made by gluing a flat sheet of paper to a corrugated (wavy) sheet of paper. The waves are known as fluting, and each individual wave is a flute. All corrugated packaging material will have a wavy texture when viewed from the side. By using smaller cardboard shipping boxes designed with custom product packaging, Packsize customers significantly reduce their corrugated packaging spend.
