plotted as a Dynamic Cushioning Curve, Table
1 represents the
curves for five different thicknesses of a single polyethylene
product for the same drop height.
note the portion of the curve for the chosen thickness which lies
on or below the fragility line. This defines a range of static
loadings that will provide the desired cushion performance, as
shown by the shaded area in Table
2. Any static loading value from within this range
can be used in your case design to attain the desired result.
By dividing the weight of your equipment by the
chosen static loading value, the result is the number of square
inches of foam that should be used to support the product in the
By repeating this procedure with several types
of cushioning materials, we generate comparisons which allow us
to strike an economical balance between cost and case size.
