In order to keep the contents of your bottle safe and uncontaminated, you need a good quality seal. Heat shrink capsules are made from a special material that when heated will shrink and form a tight seal. This in turn protects the contents of your bottle from dust, dirt, or other contaminants from getting in.
We have a wide range of shrink capsules for bottles in stock, including a variety of different colours. They are all made from Polyvinyl Chloride (PVC), one of the most common synthetic plastics around.
