Constantia Haendler&Natermann Chang Beer
Constantia Haendler & Natermann has created a thin neck foil label for Chang Beer which uses an 8.8µm, soft tampered, aluminium foil alloy. This offers material savings and downstream advantages during the recycling/reuse process.
The thickness of neck foil has been reduced, over time, from 13µm to 10.5µm and most recently down to 9.5µm. In addition to material savings of 8% the neck foil has a positive impact on wastewater used during the returned bottle cleaning process. The thinner foil completely dissolves in the caustic bath, extending the caustic wash efficiency by up to 10%. This leads to lower emissions of hydrocarbon and less heat dissipation from the washer, says the company.
