Interesting topic: I've never seen expiry date on our packaging which is plastic bottles, cups, pails, lids, etc. Just wondering if any of our members experienced their packaging being expired.
In most cases no. Most packaging material is relatively chemically inert, and stored in clean climate controlled conditions it will get discontinued for outdated artwork before it would expire. The one exception I can think of is a flexible pouch film that has an integrated oxygen absorber layer -- it's reactive, so it has a relatively short life on the roll.
For the OP I wouldn't expect glass bottles to have a shelf life. Glass is stable enough to last longer than any human civilization. The caps, maybe, if they have a plastic/rubber ring or film to aid sealing.
