Tampering seals vary in their reusability (one-time and multiple-time use), and in their production material (metal and plastic). More rigid metal fasteners are utilized to secure cargo during transportation so that any break-in attempts are noticeable, but the seal is not damaged during transportation in harsh conditions. Plastic seals are used for stationary applications - rooms, cabinets, boxes, etc. We provide a collection of seals from the best manufacturers.
