Adding a clear shrink band to a product will offer them an extra level of safety and our 100 mm X 70 mm clear shrink bands are a great choice for adding protection to 4 oz plastic straight sided jars. These shrink bands provide a 2 mil thick, PVC plastic, tamper-evident seal and have a single vertical perforation to make removal much easier. A heat source is required to apply these shrink bands and our heat gun kit can ensure the process will be fast and effective.
