Based Security Seals Manufacturer, Discusses Tamper-Evident Seals
Nov 03, 2017

Typically, there are two types of seals used to secure goods in supply chain security programs. Indicative seals, also known as tamper-evident seals, demonstrate if an item that has been sealed was tampered with. They are easily broken or cut open with light tools, as their function is to demonstrate entry, not deter it. Indicative seals are usually made from plastic (adjustable for fixed length) and metal (metal strap seals). Barrier seals (bolt seals or cable seals) are higher-strength seals that provide tamper evidence and serve as a one-time lock to slow down and deter theft or vandalism. They require large tools to cut open, and are often used on long-haul trucks, ocean containers, and rail cars.
