In my opinion, the manufacturer saved money in the wrong place. If the customer is willing to pay more than CHF 0.05 for a label, then they should also be able to easily remove them from the label.
The individual labels are very difficult to remove from the backing film. The last delivery (about 1 year ago) was much better. It looks like the manufacturer has gone cheap cheap cheap. For our users, this is a 'struggle'. It's a shame, I'll check with digitec to see if I can return these and have them replaced with the tried and tested labels.
