How do we deal with different thicknesses of foil in Pickler? And does it affect our results, since the scores are compared per kg?

In Pickler, the different thicknesses of foil don't affect the eco-score comparison, as it's based on 1 kg of packaging material. This allows for fair comparisons regardless of size or thickness. However, the energy needed for rolling thin aluminum sheets (7-12μm thick) is taken into account during the calculation. While weight reduction won't lower the eco-score, it may reduce eco-costs and carbon emissions, which are important for optimizing environmental impact.
