Measurement

When ordering your box, it is important to understand the correct way of measuring the box that you need.

Without exception, three dimensions always express the size of a corrugated cardboard box: Length, then Width, then Height (also called Depth). These measurements refer to the internal dimensions of the box.
The Length is the larger dimension of the box’s opening.
The Width is the smaller dimension of the opening.
The Height is perpendicular to the opening.

If there is still some confusion as to exactly which dimensions go where, you can always call one of our experienced sales people and they would be happy to help you in determining the correct measurements of the box you require.

Board Types

It is important to know the type of board that you will require when ordering your boxes. There are two factors to consider when choosing the type of board - either corrugated or solid board.
When choosing corrugated the flute and the wall construction should be chosen.
When choosing solid board the thickness of the board is determined by microns, ie 1000 microns = 1mm thickness

Corrugated Flutes
When dealing with differing types and styles of cardboard, we often refer to its flute, or flutes. What is a flute? Well, it simply means the type of corrugation that is sandwiched between the two outer layers of cardboard.
The larger the flute, the stronger the box.
Below is a small break down of the three types of flute that we offer at Instabox and their respective strengths and weaknesses.

“C” Flute Thickness = 4 to 5mm Flutes per foot = 41	“B” Flute Thickness = 3mm Flutes per foot = 49	“E” Flute Thickness = 1.5mm Flutes per foot = 95
“C” flute cardboard has a high stacking strength and a resistance to being crushed. It is one of the most commonly used flutes for shipping boxes and tends to perform the best when holding materials such as glass, furniture and food products.	“B” Flute cardboard is the perfect combination of strength and style. It has a higher resistance to punctures than the other flutes. Generally used for stand up displays or ballot boxes as well as small to medium sized transit outers..	“E” Flute is the most lightweight of all the types of corrugated cardboard we carry. It is a stronger alternative to paperboard and performs well when used for die cut designs. “E” Flute has a superior printing surface and works well when used for software packaging or point of purchase boxes.

Corrugated Wall Construction
Although most people think that cardboard boxes have only one type of structure there are actually two different styles of wall structure that we offer to our customers. Depending on which characteristics and qualities you would like to have in your box, you can choose from single or double wall structure.

Single Wall Corrugated Cardboard This is the most popular corrugated material used in the boxes we manufacture. It consists of one layer of fluting sandwiched between two layers of paper. It is available in a wide range of paper weights, from 125 grammes per square metre right through to 300 grammes per square metre.

Double Wall Corrugated Cardboard Standard double wall structure is made of one layer of “B” Flute and one layer of “C” Flute. (For export quality the structure will be one "C" flute and one "A" flute.) Stronger than a single wall structure, double wall enables heavier objects to be shipped and should be used when a stronger box or extra padding is needed. Double wall is available in 150 grammes per square metre to 300 grammes on standard grades and 440 grammes on export. and is excellent for stacking heavier items.

Solid Board
From 450 mcron right up to 3900 micron thickness. Available in (grey) Unlined, White lined, Industrial Kraft - both single and double sided along with White lined double sided.
