Let’s put ourselves in situation. It turns out that a new business needs to choose packaging material for its storage and transportation of merchandise. After assessing an infinity of options, he decides to carry out a study among the companies in his environment to ask for advice: “What is the essential basic in your portfolio of packaging products?”, he asks. The answer? It is very likely that the vast majority will answer unanimously: “The quality of the cardboard boxes”.
3 methods that will help you measure the quality of your cardboard boxes
Currently, due to the abundance of cardboard box designs, it is not easy to choose the option that best suits the characteristics of your company. If your business is dedicated to the transport of fragile products, you should choose the box that has a wide grammage and thickness to avoid any possible impact on the merchandise. In the textile industry, on the other hand, a lighter cardboard box would do. However, if you decide to align the use of your box with the philosophy of your company and transmit a sustainable message, recycled cardboard boxes are the product you are looking for. But what if we combined all the features in one box?
Throughout this article you will find a list of tips that will help you measure the quality of display boxes
Edge crush test: what is it?
Many times, due to the overload of weight that we place on top of the boxes, it is likely that they will be crushed and deformed, damaging the products inside. By means of the edge crush test (ECT) (Edge Crush Test, in English) we can check the resistance of the corrugated cardboard box (corrugated) and see what is the weight limit that they can support. To do this, a compression of the board is carried out at the edge of the box (perpendicularly) until the board is saturated when it reaches its maximum load. In this way, we will know, with greater precision, the stacking resistance of our boxes.
Porosity of the cardboard box
The level of porosity of the cardboard box will help us to know the resistance of the material to liquids/humidity. The process is carried out using Cobb size testing machines; which are used in corrugated fiber materials that have a high absorption. During the test, water is poured onto the material, while it is then subjected to a pressure treatment to remove the water (usually with steel rollers).
The box will be weighed twice; when the material has absorbed the water and after the extraction of the liquid. In this way, both weights will be compared (the Cobb value refers to the difference between these weights). The most resistant boxes to water or humidity have very low Cobb values.
