The B Seal is a special purpose pull-tight seal manufactured from two dissimilar materials. The Acetyl insert is durable and will withstand freezing and boiling conditions, whilst the polypropylene body is flexible for easy use. 

The design features rolled heat staking technology to secure the insert to the body, which provides clear evidence of tampering if forced open or cut.

This seal is an ideal alternative to the conventional arrow type seals commonly used to secure ballot and tote boxes and has the advantage of a neatly designed hinged tag, which fits flush to the side of the box, allowing easy reading of a security number and/or barcode.
