Utvärdering av den uppmätta greppstyvheten hos olika kartongmaterialegenskaper och geometrier (Swedish)
Abstract [en]

This candidate thesis reports the findings of a study on an objective method for measuring grip stiffness in carton board packages with different geometries and material properties. Syntouch Biotac and a tensile tester were used as an objective method for measuring grip stiffness. In this project tests were carried out on packages with three different grammages and two different geometries. For each grammage and geometry, ten packages were tested.

The study identifies that the applied method for the measurement of grip stiffness works to measure the change in grip stiffness regardless of where a load was applied on a package. Furthermore, the method demonstrates reasonable results. Finally, the study concluded that the objective testing method could distinguish between different material properties and geometries of the cartons being measured.

Abstract [sv]

En studie om en objektiv metod för mätning av greppstyvhet hos kartongförpackningar med olika geometrier och materialegenskaper rapporteras här. Syntouch Biotac och en provdragare användes som objektiv metod för mätning av greppstyvhet. I detta projekt utfördes tester på förpackningar med tre olika materialegenskaper (ytvikter) samt två olika geometrier. För varje ytvikt och geometri testades tio förpackningar. Studien visar att den maskinbaserade metoden för mätning av greppstyvhet fungerar för att mäta förändring i greppstyvhet oberoende av på var tryck appliceras på förpackningen. Dessutom påvisade studien rimliga resultat. I studien kom författarna även fram till att den maskinbaserade metoden kan skilja olika materialegenskaper och geometrier åt, vilket är verifierar metoden.
