What adhesive or attachment method works best for securing objects to bottles on a production line, while resisting temperature and humidity changes?

Members who've tackled this recommend a trade-off between permanence and production speed. **Glue (liquid adhesive)** holds better through temperature and humidity fluctuations than glue dots, but requires setting time, which can slow bottling-line integration. **Glue dots** are faster to apply but significantly less reliable for permanent attachment and can ping off under pressure (e.g. when sliding bottles into tight case dividers). **Self-adhesive strips added to the label by the manufacturer** is considered the better all-around solution by experienced members, avoiding the need to glue during production while maintaining durability. One member noted their whisky brand successfully glued a bell into the bottle punt by hand-applying glue as bottles left the line—though this was labour-intensive and the bell was partially protected by the punt design itself. If the attached object protrudes significantly or your case dividers are tight, glue dots are particularly risky as they can detach during handling.
