The 75 mm X 57 mm clear shrink bands are perfect for adding protection to 1 oz plastic thick wall jars, 1 oz glass jars, and even 4 oz plastic spice bottles. These shrink bands are designed to create a 2 mil thick, tamper-evident seal around the closure of a product to make sure they are secure and can not be easily opened or damaged. These shrink bands have a single vertical perforation to make their removal very simple and these bands can be paired with our heat gun kit for a more effective applying process.
