HOME > Pull tight seals - Smooth round stem > Uni 300


The Uni 300 has a round, smooth strap and embedded spring metal jaw. This results in a user-friendly, yet secure pull-tight seal. Contrasting markings and barcode makes it highly readable.

Optional tearline helps removal of the seal without any need of tools. Optional back labels can be pasted on documents to reduce human errors when recording down numbers.
