The database may only be used for environmental studies regarding product development and improvement and the comparison of the entire system of corrugated board packaging with that of other materials. The database may not be used for comparisons between the production of primary fibre and recovered fibre based materials as such.

The production of corrugated board is normally expressed in m2.

For LCA it is preferable to have it expressed in weight.

The table shows the calculated inputs and outputs for the production of 1 tonne of corrugated board in Europe with an average paper grade composition. The explanation of the calculation is reported in chapter 2.3.

For the average corrugated board product the paper input is 1,10 tonnes/tonne corrugated board, with an output of 0,10 tonnes paper for recycling.

Please note that corrugated board boxes are far from standardised. They show a huge variation in composition, design and appearance. Boxes are tailor-made to fit the box user’s needs and requirements determined by the product to be packed. The amount of paper and glue percentage of trimmings/shavings vary according to the design of the packaging.
