Cardboard box is the most widely used packaging products, according to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., has a variety of specifications and models. Cartons are commonly used in three or five floors, seven layer use less, each layer is divided into paper, corrugated, core paper, surface paper, in, the paper has tea sheet paper, kraft paper, cardboard, paper with corrugated, Rigid Paper Box a variety of color and feel is not the same, different manufacturers of paper (color, feel) is not the same.
