When adding protection to thick, heavy, or even double wall 4 oz plastic jars, the 115 mm X 72 mm clear shrink bands are a perfect choice. These shrink bands will create a 2 mil thick, tamper-evident seal that will contribute an extra layer of safety and limit the chances of products being damaged or opened. These shrink bands have a subtle, single vertical perforation that makes for easier removal and can be paired with our heat gun kit to ensure an effective application.
