What is corrugated?
Corrugated boxes are easy to recognize. Corrugated is made of paper and has an arched layer, called "fluting," between smooth sheets, called "liner." The corrugated most commonly used to make boxes has one layer of fluting between two smooth sheets. This structure gives corrugated board considerable rigidity and resistance. The air circulating in the flutes also serves as an insulator which provides excellent protection against temperature variations.
Why corrugated?
Corrugated is not just a brown box. Corrugated is a complete, high-performance material design, manufacturing and delivery system. Corrugated is the preferred packaging material because it is:
| ► Durable | ► Versatile | ► Lightweight |
| ► Environmentally Friendly | ► High-Tech | ► Customizable |
| ► Cost-Effective | ► Protective | ► Graphically Appealing |
How are corrugated boxes made?
The box building process is not complicated. Boxes are made of corrugated paperboard, starting off as rolls of liner and corrugating medium. Corrugated board can be made up of one or two layers of flutes and liners, depending on how strong the box needs to be. After that the flat corrugated boards will be converted into boxes by flexography printing presses, die-cutters, gluers and stitchers. Flexo printing presses can print any type of boxes as well as crease, slot and trim the RSC box at once. For the die-cut style boxes, we use the die-cut machines to cut the corrugated boards one by one into the pattern the customer will fold into the box shape. The final process is to join the box either by gluers or stitchers so that the boxes can be shipped flat and then be easily formed by the customer and packed.
What are the constituents of the RSC box?
There are many constituents of the RSC box. The figure below gives details on how the parts are called.
How to specify a box dimension?
Dimensions are given in the sequence of width, length and depth. Internationally, the words length, breadth and height may be used to express these dimensions. The dimensions of a box are described based on the opening of an assembled box, which can be located on the top or the side, depending on how it is to be filled. The opening of a box is a rectangle; that is, it has two sets of parallel sides. The longer of the two sides is considered its length, the shorter of the two sides is considered its width. The side perpendicular to length and width is considered the depth of the box. Dimensions can be specified for either the inside or the outside of the box. Accurate inside dimensions must be determined to ensure the proper fit for the product being shipped or stored. At the same time, palletizing and distributing the boxes depends on the outside dimensions. The box manufacturer should be informed as to which dimension is most important to the customer.
