The 84 mm X 54 mm clear shrink bands are an ideal fit for 2 oz plastic straight sided jars and will offer them added protection with a tamper-evident seal. These PVC plastic shrink bands are 2 mil thick but can be easily removed with little effort because of their single vertical perforation. A heat source is required to properly apply these shrink bands and SKS offers a heat gun kit that will ensure the effectiveness of the application.
