62 mm X 62 mm clear shrink bands are designed to fit 2 oz plastic round and boston round bottles and will give products added security and protection through a tamper-evident seal. These shrink bands are 2 mil thick, but can be effortlessly removed because of their single vertical perforation. These perforated shrink bands need a heat source to be applied and here at SKS, we offer a heat gun kit that can make the process very quick and simple.
