Strong, stretchable film forms an air tight barrier when stretched across openings. Will cling to itself and to glass vessels and can stretch 300-400% before breaking or tearing. Clear film is UV transparent and has no liner paper to remove. Greater heat and chemical resistance makes DuraSeal Cling useful for more applications than paraffin based films.
