This week I went to the Migros supermarket - Winterthur - Rosenberg unpacked station and filled our storage container directly with Flöckli mixes. Thanks to the taring option, you can even mix various ingredients. At home (2-3 hours after shopping) I wanted to remove the labels from the storage container (made of BPA-free plastic), but no luck! The labels are practically impossible to remove -> I poured the contents into another container and soaked the label residue in water. Partial success: I was able to rub off the paper parts, but the glue was still stuck! Now I tried using petroleum ether - a little came off, but it was still stuck! Now: after a round in the dishwasher, you can hardly see anything anymore - BUT: it's still stuck! Understand me correctly: I don't want to know from you and from MIGROS what I have to do to finally get the container clean again! No! I want to know why these labels stick so unspeakably well? Surely that can't be the purpose? What are your experiences with the labels?
