It is very important to know the type of cardboard that you will require when ordering your boxes. There are two factors to consider when choosing the type of cardboard – the flute and the wall construction.
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 = 11 / 64″
Flutes per foot = 41
“C” flute cardboard has a very high stacking strength and a higher 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
Thickness = 1 / 8″
Flutes per foot = 49
“B” Flute cardboard is the perfect combination of strength and style. It has a higher resistance to punctures than the other flutes and usually consumes less space than the regular “C” Flute. It is most often used for boxes that have to be durable but also need to have some style. Generally used for stand up displays or ballot boxes.
“E” Flute
Thickness = 1 / 16″
Flutes per foot = 95
“E” Flute is the most lightweight of all the types of corrugated cardboard we carry. It is a stronger alternative to paperboard and performs great when used for die cut designs. “E” Flute has a superior printing surface and works best when used as software packaging or point of purchase boxes.
