The 90 mm X 32 mm clear shrink bands are for adding protection to larger containers, such as 16 oz plastic square bottles and 950 cc glass pharmaceutical round bottles. These shrink bands are designed to give products tamper-evident seals that improve their safety and limit the chances of them being damaged or opened. These shrink bands are simple to remove because of their single vertical perforation and they can be combined with the heat gun kit we offer at SKS for a more effective application.
