The label lifted
Updated

How it happens
Formula wiped down the side at filling, or a few drops from a sprayer in use, and the alcohol works under the facestock. A corner lifts, the print goes translucent, or ink smears where a thumb passed.
The archetype says so directly
High alcohol attacks plastics and adhesives. The adhesive half gets less attention than the bottle half, and it is the one the customer sees every time they pick the product up.
Glass is a good surface, which helps
Adhesion to glass is easier to achieve than to a low surface energy plastic, so this shelf starts from a better position than the HDPE shelves elsewhere in this library. The attack is chemical rather than mechanical.
Four suppliers, one symptom
Facestock, adhesive, ink and overlaminate each fail differently and are each bought from someone else. Specifying them together, against your actual alcohol percentage, is what turns a recurring complaint into a solved problem.
An overlaminate or a varnish is the usual answer
It protects the ink from wiping and slows the alcohol reaching the adhesive at the edges. It also changes the feel of the label, which in a premium fragrance is a deliberate decision rather than a default.
Test it the way the product is used
Label a filled bottle, wipe the formula down the side, handle it daily for a week and then look at the edges. That is the condition the label has to survive and it takes one bottle to reproduce.
And decide before the print order
Labels are bought in quantity and a lifting edge cannot be fixed with a second label. The test costs a week and the print order costs a lot more.
