All About Box

The Basics

Measurements BoxBox sizes are measured by using inner dimensions unless otherwise specified. The size of your contents actually determine the inner box dimensions. Domestically (within the United States), those dimensions are listed in the following sequence: Length (L) x Width (W) x Depth (D)*. Internationally, the dimensions are stated as Length (L) x Breadth (B) x Height (H).

Dimensions are based on the opening of an assembled box. Looking at the opening, the longer of the two sides is considered the "length." The shorter of the two sides is the "width." The side perpendicular to the length and width is the "depth" of the box.

How to measure a box - Quick Guide Line

Measurements BoxLooking at the opening of the box, measure the longest or length panel first. Using a tape measure, place it in the bottom of the box approximately one inch from the back wall and measure from left to right. Repeat the process for the shorter width panel. Then, folding a side flap inward until it is perpendicular to its vertical side wall, place the tape measure at the end of the flap and extend it downward until it rests on the inner flap at the bottom of the box (see illustration). This exercise will give you the depth dimension of the box.

One-piece, die-cut boxes, such as the "mailer-style" with a tuck-in top, do not have flaps when assembled, but the measuring procedure is basically the same. For the box depth, use the inside back panel as it has a visible score line (crease separating back panel from lid). For the width of a die cut box, measure between the score lines found on the inside of the top or lid. And, of course, for the length of the box, place your measuring rule on the bottom of the box approximately one-inch from the back panel. Measure from left to righ


Corrugating is defined as the imparting of wave-like shape to a paper.

Kraft paper or fluting media paper is passed through heated corrugated rolls to obtain continuous rolling, wave-like shape. These are called flutes. Observed vertically,  they form a row of columns -  a basic structural form capable of supporting great weight. Viewed horizontally, flutes are arches- another basic structural form capable of providing cushioning properties.  The combination of columns and arches pro –duce a material far stronger then the paper from which it is converted.


Depending on the strength properties required, different types of flutes are used. Generally four different types of flutes, known as A,B,C and E are available. Recently

Fluted paper, when stuck to another flat sheet of paper gets converted into 2- ply corrugated board. 3-ply corrugated board has one fluted paper and two flat papers. Similarly, 5-ply, 7-ply and 9-ply corrugated boards are manufactured by converting multiples of flat papers and fluting media papers.

Corrugated boards can be easily cut to any shape and creased to fold in any direction. Thus, corrugated boards can de further converted to produce cartons, boxes, cases, containers, inherent fitments /accessories such as interlockers, partitions, dividers, pads, plates, supports, fillers, etc. which provide internal cushioning and restrict movements. The  various shapes and forms described above are referred to as ‘corrugates boxes’ for the sake of brevity.

Because the corrugated board is a very versatile packaging material, various styles of packaging are available, to suit the specific requirements.

In order to standardise the nomenclature throughout the world , an international box style depends on the product, its configuration and other packaging, transport and storage requirements.

The most popular style is the universal type box (Regular Slotted Box), because it is the most economical to manufacture and is adaptable to the packing of most end products. Some of the other popular styles are lock bottom, auto slot carry home and self-locking tray.

In addition to functioning as transport containers, corrugated boards are also used as inner fitments and accessories, known in industry as inherent fitments. The anchor the contents within the outer box to arrest transit movement . they provide cushion and protect fragile articles from damage during transit.

Corrugated Packaging In Prespective
The word 'packaging; no more sounds new even to the common man. Today, most of the products are offered in packages that are convenient, modern and attractive. Packaging has come to play a vital role in today' life. More and more people - both producers and consumers of goods - are becoming aware of the importance of effective packaging. In the present competitive market, packaging contributes significantly to the success or faiure of product.

Almost all products are required to be packed scientifically in order to ensure that the product reaches in its original form and shape to the end consumer.


Packaging which is a concept considerably advanced from packing, is today inextricably interwoven into the matrix of our marketing system. This, in term, is a sequel to the rapid urbanisation and industrialisation that is taking place in our country. The range & the variety of the products now being manufacture and the increasing public awareness of the advantages of buying package item have made the packaging Industry one of the most dynamic segments of our industrial economy. In the sphere of exports too, packaging has assume special importance because it helps realize higher returns in value terms. 

Among the various modes of packaging that are being continuously developed, Corrugated Packaging strands out as the most versatile, secured, efficient & economical. The very fact that almost 95% of all the products in the western worlds are take in corrugated boxes as transport containers establishes that corrugated packaging is the most viable & internationally accepted mode of packaging. The growing awareness of the need to maintain environmental & ecological balance has further enhanced the importance of corrugated packaging in the modern world.

 Even when viewed from this one angle alone, corrugated packaging stands out as the most significant mode of packaging of the modern times.
