SKS offers the 45 mm X 58 mm clear shrink bands here in a bulk option and they create a strong line of protection and safety for products through tamper-evident seals. These shrink bands are great for long neck bottles, such as 10 oz glass sauce bottles and 14.5 oz woozy bottles. These shrink bands offer a single vertical perforation for easy unwrapping and are applied through the use of a heat gun, which we carry at SKS.
