In theory it should last longer but as to how much longer? I suppose it depends on the seal. I don't think most wraps are vacuum sealed. It's just a protection seal to show the bottle is unopened. I would think that as long as the cap is tight, you'd get the best longevity out of the juice. Vacuum sealing removes the air, which is the main cause of degradation. But I don't think juices are vacuum sealed.
