Wire Seals vs Plastic Seals: Which One Is Better for Your Business?

What Are Wire Seals?
Wire seals are made of metal wire with a locking mechanism that ensures tamper evidence once applied. They’re designed for industrial use, offering high strength and durability.

When it comes to cargo protection and tamper prevention, both wire seals and plastic seals are popular options. Choosing between them depends on your shipment type, budget, and required security level. Let’s explore how they differ and which one best suits your business.

Key Features:

  • Flexible stainless or galvanized steel wire
  • High tensile strength
  • Resistant to heat, pressure, and corrosion
  • Tamper-evident — any attempt to cut or twist is clearly visible

Common Uses:

  • Cargo containers and tankers
  • Electric meters and fuel meters
  • Chemical drums and storage tanks
  • High-security logistics and manufacturing facilities

What are plastic seals

Plastic seals are lightweight, single-use seals made from durable polypropylene or nylon.
They’re ideal for low- to medium-security applications where quick sealing and disposal are needed.

  • Identify your security level (low, medium, high)
  • Match seal type with cargo weight and transit duration
  • Always choose tamper-evident and numbered sealsCost-effective and easy to use
  • Tamper-evident locking design
  • Available in multiple lengths and colors
  • Can include serial numbers or barcodes for tracking
