<p class="MsoNormal">At least 20 years ago (before my time here), white plumbers’ tape was wrapped around the edge of the lids and onto the sides of all the bottle and jars in a certain section of our alcohol collections. This is the PTFE tape that plumbers
use to seal threads; it is thin, soft and non-adhesive. Presumably the idea was to provide a secondary vapor barrier in addition to the jar lid seal.
<o:p></o:p></p>
<p class="MsoNormal">We are now doing long-overdue major maintenance on this collection, and are trying to assess the efficacy of this tape. I’d be very interested to hear from anyone who (a) has used it and can show it works (b) has used it and can show it
doesn’t work, or (c) who considered using it but decided not to, and why.<o:p></o:p></p>
