Parafilm is commonly used in labs to tightly close and seal vials, bottles, jars, etc. containing liquids or solids. I use it often to seal partially used glue containers. It stretches and conforms to the shape of the tube or bottle and forms a good seal. It can be wrapped around multiple times and it sticks to itself very well because of stretching. For this reason it can stick better than kitchen plastic wrap, and it's also chemically relatively inert and resistant to many chemicals, including strong acids and bases (for some time. ) It seems expensive, but the package is heavy and it last for a long time if used for its purpose. It's generally not used for very large openings, like food containers or trays. The best way of removing the paper backing is to slightly stretch the film until the paper tears.

Works as advertised. This is the perfect material to preserve expensive bottles of unopened scotch. Acts as a secondary airtight barrier incase of cork malfunction.
