Cost Metric
Formula used by packaging buyers to determine the total number of usable finished units produced per ton of raw material after accounting for all process losses. A landed pack yield calculation integrates the nominal grammage of the board with the actual conversion efficiency of the printing and die cutting lines. This figure provides an accurate picture of procurement costs.
Efficiency Variables
Differences between the theoretical yield and the actual output are caused by factors such as trim waste, make ready losses and spoilage during the finishing stages. Performing a landed pack yield calculation allows the buyer to compare the value of different board grades that may have different moisture contents or thickness tolerances. A board that is easier to run on the press may offer a better total cost even if its price per ton is higher.
Procurement Strategy
Regular audits of the conversion data help to refine the assumptions used in the initial cost models. When the landed pack yield calculation shows a decline, the cause is often found in poor board quality or inconsistent machine settings. Maintaining a high yield is necessary for the financial sustainability of high volume packaging operations where margins are narrow.
Accurate reporting ensures that material choices align with production goals.
