Due to its high strength and low density, the corrugated fibreboard (CFB) box is one of the most popular types of packaging all over the world. This packaging device is able to fulfil a huge number of requirements of the logistic process, during the phases of handling, shipping and storage. In addition to this, corrugated packaging is easily machinable, so it is also suitable for special supply chains and products. These special needs include the requirement to fit to the inner measurements of the shipping device, e.g. the shipping container. This is particularly expected in case of less than container-load (LTL) shipments, where the shipping cost is usually based on the required area (m2) or cubic capacity (m3) of the container, so the useful filling of the shipping device is a very strong advantage. Naturally, this is easily solvable with different CFB boxes which have different heights, but this way the user needs to stock a high variety of boxes, requires a good relationship and cooperation between the parties and also a proper knowledge of product organisation in each box version. The multi-depth corrugated boxes are a suitable solution for resolving this problem. These boxes are creased at multiple intervals, so they are easily cuttable to the desired various heights. But the pre-scored lines can cause a loss of the compression strength capability of the box and thereby can lead to damages. The aim of this paper is to determine the effect of multiple creasing lines on the compression strength of the CFB box. This paper does not focus on the effect of either different creasing parameter, such as depth and width, nor on the distances between each creasing. Based on the test results, the compression strengths are decreased nearly significantly due to the additional creasing line(s).
