It is well known that transportation means high and varying stresses for products as well as packages. To develop boxes with the ‘right’ amount of material and the right construction is crucial. The vibrations and shocks acting on pallets during transportation are transferred to the corrugated boxes and considerably reduce the strength and life time of the boxes. Important parameters to consider are stacking strength, load distribution and the degree of stacking misalignment. This paper presents a technique for investigating these stresses based on a pressure sensitive film, which gives many measuring points and a pictorial description of the stresses that occur. A series of tests using static as well as random and sinusoidal vibration testing have been done utilizing this technique and results have been presented for different positions on the pallet. Also advantages and disadvantages with this technique will be described and new knowledge possible to elaborate will be discussed.
