Plastic Pull-through Security Seals

Plastic pull-through / pull-tight security seals (referred to variously as anti-tamper, tamper-evident & tamperproof tags and seals) provide cost-effective protection and security against unauthorised tampering of sealed enclosures. The tail of the seal 'pulls through' the locking chamber and 'pulls tight' around the enclosures being sealed. They are particularly suited to seal the neck of cash, mail or waste sacks where it is important to form a tight seal to reduce the ability to interfere with bag contents. Pull-tight seals are by their nature low- or medium-strength "indicative" seals; a broken or tampered seal can 'indicate' that your supply chain has been breached, and that the chain of custody of items (such as commercial cargo sealed in trucks, trailers and containers) has been broken. Please note, that for stronger seals which delay intrusion physically, please see our metal cable barrier seals.

Pull-through anti tamper seals are available in many different pull strengths & configurations, including all-in-one moulded seals, metal insert seals, tear-line and easy-break security seals. They can suit lightweight applications such as fire extinguishers, first aid boxes and crates; all the way up to sealing truck and trailer doors, oil tankers and air cargo... whatever the application, Universeal has the right tamper-evident seal to suit the application. We supply many of our tamper seals from stock sequentially numbered in popular colours, or custom printed with company logo, barcoding or bespoke numbering on short lead times.
