The 100 mm X 70 mm clear, PVC plastic shrink bands are applied using a heat source and are a great fit for 4 oz plastic straight sided jars. These shrink bands will provide products with additional protection and give them a tamper-evident seal that will improve their safety. These shrink bands are perforated with a single vertical line to make the removal process much easier and they can be paired with our heat gun kit to make applying quick and efficient.
