For adding extra protection to small plastic jars that are 20 ml, 1/2 oz, or 1 oz in size, our 86 mm X 45 mm clear shrink bands are a perfect choice. These shrink bands offer a 2 mil thick, tamper-evident seal that will ensure the safety and protection of a product. Removing these shrink bands is made easy because of their single vertical perforation and they can be paired with our heat gun kit to make applying more efficient and simple.
