Constantia haendler & natermann has created a remarkably thin neck foil label for chang beer which uses an 8.8µm, soft tampered, aluminium foil alloy. The thickness of neck foil has been reduced, over time, from something like 13µm to 10.5µm and most recently down to 9.5µm. This not only offers material savings, but also downstream advantages during the recyclingreuse process.
