In order to make them gluable with conventional liquid label glues they have to be surface oxidized by flame or corona discharge (electron bombardment).
The treatment will wear off with time. Gluability can be determined with a dyne kit. Our lab can test for gluability or show you how to.
The manufacturers of poly bottles will often offer “treated” bottles. The manufacturers of poly coated glass bottles do not.
Adhering to “untreated” poly bottles or poly coated glass requires specially formulated glues.
