Furthermore, our industry experts are on hand to recommend improvements or customised solutions that are applicable to your needs. My area of expertise is corrugated boxes. I’ve been in the industry for over 30 years in a wide range of roles from structural and graphic design through to manufacturing and sales. Yes, I’m what is generally known in the industry as a typical box head.
Today I’m going to share a little general knowledge and some basic information on board grades and boxes. A little knowledge can go a long way. For those who may find boxes interesting, I’ll be adding bits and pieces as we
The actual performance of a corrugated fibreboard box depends on the properties of the paper used and on the onstruction/design of the container.
Corrugates boxes can be used for anything from shipping goods to packaging and storing. Here is useful information you need to know about corrugated packaging! Pro-Pac Packaging is here to answer any questions you may have
What is the overall corrugated box structure and what are their advantages?
Let’s begin with board grades
Corrugated board is a composite structure made up of at least one corrugated layer and at least one flat layer.
The corrugated or “fluted” layers are generally called “medium” or “flutes”. The flat layers are called “liners” There are many combinations of paper types laminated together to make up the sheets that then are converted into the fnished product.
The flute or medium which is the corrugation between the sheets is generally made using recycled paper. Recycled paper tends to hold its shape better than virgin paper/ Kraft as it has less rigidity due to shorter fibres. The paper laminated to the corrugated mediums more commonly known as liners can be made from 100% recycled paper or 100% virgin Kraft and comes in various grades and thickness. These liners combined with the mediums make up
the corrugated sheet and determine its strength factors which all have various codes to identify what board grades they are.
Single Face Rolls
This is made up of various grades of paper laminated together. The makeup of single face is one liner and the medium or “corrugated flutes”. Single face is supplied in rolls and is widely used for general wrapping and protection of goods etc.
Single Face Rolls
The most commonly used flutes for general shippers are B, C & A.
The differences in board grades are the thickness of the flutes and paper combinations.
B = 3mm
C = 5mm
A = 7mm
There are also double wall and triple wall sheets made that are a combination of these flutes, used for heavy duty products.
BC = 7mm
ACCC = 15mm
E = 2mm
F, D & E Flutes are very narrow. These grades range from 1mm to 2mm in thickness with a much tighter corrugated profile. These grades are used for small intricate die cut cartons or inserts etc. aging and increase recycling rates.
Die Cut Cartons
Essentially there are many different profiles for cardboard products that are dependent on the customer requirements, final use and needs. Also, with cardboard being largely recycled product, it is the ideal “green” packaging material.
