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:

Key F1-2

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), Vprod:

Calculated or measured

 

Volume of the primary packaging, Vp:

Key F4

or the formula for the given shape of the packaging.

 

Volume of secondary packaging, VS:

Key F4

or the formula for the given shape of the packaging.

 

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

Key F5

or the formula for the pallet or load carrier used.

 

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

Key F6

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

Key F7

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

Key F8

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

Key F9
