We've got a Nordic style bottle for vodka with synthetic cork bar top. The tops fit perfectly, snuggly, but seem to creep up on some bottles over time. We're going to use a paper strip over the top for the breakable seal (awaiting labels to be delivered any day), but I'm worried that won't prevent the top creep.
Do heat shrinks over the top of the paper & top prevent the top from creeping up over time?
Also, I think its partially due to temperature changes between bottling & store.
