corrugated box size design

With the increasement of the amount of corrugated boxes in various industries in recent years, its function is also put forward higher requirements. The structural design of the corrugated boxes, especially in the transport, shelf storage, reasonable size, shape and distribution of material can not only save costs, provide the best packaging solutions, but also to ensure the most effective protection in the long term freight. In such circumstances, the structure and size of the corrugated box design is also becoming increasingly important.

The corrugated box design start from determing the nature of the product and the box templates. Make sure the box templates to design and calculate the size of various parts. The international corrugated box templates have two standards, FEFCO standard and Japan, American national standard. It should consider proper corrugated cardboard in the design or selection of corrugated boxes, including the flute-type, cardboard layers, paper specification, which were clearly defined in the standards.

Before determing the structure of the corrugated box size, we must first consider the largest diameter of the interior goods, properties and the tolerance factor of the product itself, as well as interior goods is the overall or combination package. We must also consider the addition of various accessories to protect the contents of goods. This requires a variety of factors to be considered in the design arrangement and structure layout of the dimensions of the corrugated box.

The specifications of the corrugated box template is generally the diameter size of the length, width, depth listed as the following in mm unit.

(a) length (L): the long side size of the inside end of box area;

(b) width (B): the short side size of the inside end of box area;

(c) depth (D): The size from the end to top inside of the box.

The size of corrugated box template design elements include the internal diameter size, manufacturing size, and outside diameter size. The internal diameter size of the corrugated box is the box interior space dimensions; the outside diameter size of corrugated box is the external size, it equals the caliper of the corrugated cardboard add the actual manufacturing size; manufacturing dimensions of the corrugated boxes is size in the manufacturing process, it equals the caliper of corrugated cardboard add the internal diameter size of the corrugated box.

The factors to determine the internal diameter size of the corrugated box mainly are the maximum diameter size of the contents and the tolerance factor, the arrangement of the contents, the contents partition and buffer size. The inner diameter calculation by the following formula:

Xi＝ Xmaxnx＋d(nx－1) ＋k'＋T

Xi is the inner diameter of the corrugated box, Xmax is the maximum diameter size of the contents, d is the content quantities, k' is compensation amount of the internal diameter size of the corrugated box, T is caliper of the partition or buffer.

The manufacturing size can be calculated as:

X＝Xi ＋t ＋k

X is the manufacturing size, Xi is the internal diameter size, t is the caliper of the corrugated cardboard, k is the correction factor.

The outside diameter size can be calculated as:

X0=X+K

The structural packaging design starts from the actual condition of the production and packaging, the design of the packaging form factor structure and internal accessories based on scientific principles. It must ensure that the structure of sufficient strength, hardness and resistance to every kinds of environment. We must consider the following two aspects for the packaging purposes, the one is the primary function of protection products, another is important feature to meet modern packaging, such as transportation, processing characteristics.

In summary, the size of the corrugated box design is a very important work in the structural design of corrugated boxes. A qualified corrugated box should be protective and good shape, especially for packaging with function of sales packaging and transport packaging, a reasonable size corrugated box design is the key. Because changes in the size of the carton variety of performance will directly affect the change. In short, the structural design of corrugated boxes, according to the use of manufacturing equipment, production process, constituted by different corrugation of corrugated as well as interior goods type and nature. In order to manufacture corrugated boxes to protect the goods, and beautify the commodity the only way is to learn the structure design of the corrugated box and size-related content.
