Laser Marking vs Hot Stamping for Security Seals: Differences & Features

Company News, 10-16-2026

Security seals can be customized with markings as an anti-theft measure. Laser marking and hot stamping are widely used marking technologies, with obvious differences in raw material needs, color options, surface texture and custom flexibility.

One anti-theft feature of security seals is custom marking, which means printing content as requested by customers.

Laser marking and hot stamping are the two most common marking methods for security seals. Below are their similarities and differences:

1. Raw material requirements
Laser marking requires laser powder to be blended into the raw material during production, whereas hot stamping has no such requirement.
2. Available colors
Laser marking is normally black. It appears white when applied on black-colored seal products. Hot stamping typically comes in white.
3. Surface effect
Markings made by laser are flat and non-tactile. Hot stamped characters create an indented (sunken) texture on the surface.
4. Customizable size & pattern
Laser marking allows flexible adjustment of numbers, texts and logos according to customer requirements. Hot stamping uses fixed moulds, so patterns cannot be adjusted freely.
5. Serial number & barcode capability
Laser marking can print serial numbers ranging from 0 to 9. Hot stamping generally supports serial numbers of 5–8 digits (7 digits as the common option). Barcodes are usually not available for hot stamping.
