The Model #3235 puts a tamper evident seal onto the neck of a poly bag. It easy to load, does not require any operator training or tools to make changeovers, can be mounted and has a bag trimmer to trim any excess bag. TACH-IT's Tamper Evident Bag Sealers allow for the easy opening of the tape flag seal. The tape can be pulled apart allowing the bag to be opened. As the seal is pulled apart the paper liner is ripped showing that the product has been tampered with. The tape seal can then be re-used. Throat capacity: 3/8".
