CROC-Security Substrate & Performance testing

Security Documents need to be appropriate for their respective use-case. Traveldocuments, Personal-IDs, Camp-management, Landtitles, vital records etc. In many cases the documents are exposed to severe use. On one hand due to exposure to the elements. On the other hand due to the way the documents are stored or carried.

The material used for the CROC-system is based on paper made of synthetic fibres. It resembles in the make traditional security papers. However, it's robustness to the elements compares more to plastic films.


The advantage over the plastic films is evident: It integrates essential security features as required in the minimum-security standards stipulated by international organizations.

The CROC substrate combines the best characteristics of security paper, plastic card films and nonwoven textiles..

The CROC-substrate is long-time proven, with its original formulation ranging back over 50 years and having been applied in numerous governmental use-cases. The new generation has been further improved for performance, personalization, security.

"Robust" signifies heavy duty documents, fit to meet extaordinary challenges. The team of SECOIA had alot of fun to test the overal document, including substrate, personalization and security seal.

Movie 1

Trailer abstracting the tests in 1 minute. You will see:

  • Document rolled over by a tank

  • 15km / 9mi hike with the document under the shoe

  • Document "beaten" by monster-trucks

  • Submitted to dirt and gravel, rolled-over by 26to caterpillar

  • Submerged in flowing river for 33years (documented event on a previous version.
