We are all familiar with corrugated cardboard in our daily lives but not everybody knows that the corrugated cardboards might look similarly but they are very different. --- Yes, you are not reading wrongly. Before lying yourself that they are only corrugated cardboards and what could be the difference, just read our below information: Botta Packaging will introduce you with different types of corrugated board, according to their structures and durability.
This type of corrugated cardboard is only made of 1 layer of wavy paper (s-shaped flute) with 1 single smooth-paper surface. This type of cardboard is not very durable, for that reason, it is only used for wrapping the product to provide extra protection, rather than being a single packaging. It couldn’t be made into a fulfilled box.
Due to the sufficient strength and manufacturing cost, Single Wall Board is the most common cardboard type used to make fibreboxes. It has 1 layer of s-shaped flute between 2 smooth-faces. Single Wall Board are then classified into different types: A, C, B, D, E, F and G based on their flute thickness. Certain type of flutes are applied for specific type of Single Wall Board.
C-flute is the most favored type due to its flexibility. It is 4 mm thick which is sufficiently strong to make the cardboard box for some products. Single Wall Board with A-flute might be a bit loose with only 1 layer of s-shaped flute although its thickness is 5mm. Fun fact: Your pizza box might be E, B, or F-flutes.
Double-wall board is the corrugated cardboard with 2 layers of s-shaped flutes staggered with 3 smooth paper layers. Hence, it is stronger and more resistant than Single Wall Board. Of course, it would cost much more than Single Wall Board due to the extra material used. Hence, Double-Wall Board is mostly used to contain heavy objects. Different types of flutes might be used for double-wall board, depending on the requirements about strength or insulation of the product packaging. The common ones are AB, BC or EB flutes.
You can guess its structure from its name. The triple-wall board has 3 layers of flutes with 4 layers of smooth paper. It is strong enough to replace wooden crate in logistics and transportation but much lighter than wooden case. Triple-wall board is quite expensive for common use, hence, it is only used for chemical industry and some dangerous goods which need further protection or handling with care.
Whether you are a logistic manager or just an ordinary reader, we believe that above information might be helpful or interesting to you in some ways.
