1.4 How to calculate key figures in practice

DEGREE OF FILLING: Calculations of the degree of filling can document how efficient the packaging functions in transport and storing. The theoretical available space in the transport unit should be utilised as much as possible to keep the environmental impact per unit as low as possible. Empty space cost money to transport.

The degree of filling of the primary packaging can be calculated in different ways:

The real degree of filling will however often vary from these calculations. The real degree of filling of the primary packaging can be measured by dipping the product in water and measure the volume of water replaced.

The formulas used is as follows:

Volume of product (e.g. biscuits), V_prod:

Calculated or measured

Volume of the primary packaging, Vp:

or the formula for the given shape of the packaging.

Volume of secondary packaging, V_S:

or the formula for the given shape of the packaging.

The theoretical available volume of a Euro-pallet (tertiary packaging), V_T:

or the formula for the pallet or load carrier used.

The degree of filling of the primary packaging is calculated as follows, DF_P [%]:

The degree of filling of the secondary packaging is calculated as follows, DF_S [%]:

The degree of filling of the tertiary packaging is calculated as follows, DF_T [%]:

The total degree of filling for the packaging system is calculated as follows, DF_TOT [%]:
