Numerical and experimental investigation of the strength of corrugated board packages

The buckling behaviour of corrugated paper packages was studied by means of an experimental and theoretical analysis. Mechanical behaviour of paperboard was first evaluated experimentally, then a local geometry FEM model, able to reproduce with a very good accuracy buckling loads obtained experimentally in the standard edge compression test, was developed. In order to investigate the buckling of a complete package, a finite element ‘corrugated board’ was introduced by means of a dedicated homogenization procedure. The FEM model of the package, assembled with this new element, can accurately predict the experimental data of incipient buckling observed during the standard box compression test, despite the few degrees of freedom and the minimal computational effort.

Washboarding and print quality of corrugated board

This paper is a concluding survey of the research presented in three previous reports by the author. It deals with the problem of washboarding, which is the wavy pattern coinciding with the flute tips on the surface of corrugated board. The causes of washboarding on the surface of corrugated board have been determined and the effect of washboarding on the print quality of corrugated board has been studied and discussed. Measuring equipment for quantifying washboarding has been developed. Which has a non-contact, optical measuring device which measures the distance to a corrugated board sheet with an accuracy of 1 μm. The effects of paper properties and process and converting conditions on the degree of washboarding were studied and the effects of the degree of washboarding on the appearance of the unwanted stripes in flexo print (so called printed stripes) has been analysed. The main influencing factor for washboarding to occur on corrugated board surfaces is the amount of glue between the liner and the fluting. The more glue, the more washboarding. The liner grammage is also important; a high liner grammage decreases the degree of washboarding and a low fluting grammage decreases the washboarding. The degree of washboarding influences print quality to a surprisingly low extent, contrary to what has been claimed before, with other parameters influencing the printed result much more. The distance between the plate and the pressure roll (the print nip) and the ratio between the stiffness in the thickness direction of the board and the printing plate, influence quality print dominantly. The type of print, i.e. half-tone or full-tone, also influences print quality. It is not possible to get perfect printing results in both half-tone and full-tone prints when using the same inking station. To avoid printed stripes on half-tone areas one should increase the print nip, decrease the fluting stiffness and/or increase the plate hardness. To avoid printed stripes on full-tone areas one should do the opposite: decrease the print nip, increase fluting stiffness and/or decrease plate hardness. © 1998 John Wiley & Sons, Ltd.

Some experimental aspects of the compression behaviour of boxes made up of G‐flute corrugated boards

The load‐bearing capacity of boxes made up of thin‐walled G‐flute corrugated boards was investigated by performing monotonic and cyclic compression tests on boxes of various geometries. Results provided a large experimental database on the influence of the box dimensions and compression velocities on buckling parameters such as critical load and the corresponding critical axial deformation. Cyclic loading tests permitted the detection of the onset of an irreversible strain state, which could be related to damage initiation and propagation in the microstructure of the panels of boxes. Moreover, main differences, which could be observed between G‐flute corrugated boards and folding boards, were emphasized. Finally, the ability of some usual modelling approaches to predict the critical load of boxes was discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Potential of all‐cellulose composites in corrugated board applications: Comparison of chemical pulp raw materials

All‐cellulose composites (ACCs) were produced using various commercially available chemical pulps by partial dissolution method using an aqueous zinc chloride (ZnCl₂) solvent. Characterization methods used for defining material performance, keeping especially corrugated board products in mind, were as follows: scanning electron microscopy, tensile strength, 2‐point bending stiffness, concora medium test, and short‐span crush test. Hardwood (bleached eucalyptus), softwood (bleached spruce, bleached and unbleached pine), speciality softwood pulps (sulphite dissolving with 530 and 398 mL/g intrinsic viscosities), and annual plant pulp (bleached abaca) were investigated to give a broad overview of the potential for making ACCs. Softwood pulps, especially bleached, showed highest increase in mechanical properties across the board. Hardwood pulp showed relatively good results, and the selected annual plant pulp (abaca) responded partially negatively to treatment. Comparing unbleached and bleached softwood ACCs, it seems that bleaching is beneficial for tensile properties. However, when material comes under compressive or bending loads, unbleached pulp performs very well. Comparing sulphite dissolved pulps, it could be proven that pulps with higher intrinsic viscosities, thus higher polymerization grade, respond better to partial dissolution. It was proven that a wide set of pulps, also of lesser cellulose purity, used in the paper industry are viable for ACC production. Furthermore, results from short‐span crush test and concora medium tests show high potential of ACCs for corrugated board applications.
