— packaging that protects the product itself
A conventional laminate protects the product passively — it simply separates it from the environment. The CHISTEH biocidal layer based on silver ions makes the packaging active: it suppresses microbial growth itself.

Key facts about CHISTEH technology
- ≈ 2×slower microbial growth on chicken fillet — Kemerovo State University study, 6 days at +4 °C
- < 0.005mg/dm³ — silver migration below the detection limit in 5 model media
- Class IVlow-hazard substances: no alcohol, chlorine or odour, approved for food contact
- up to 67%less fruit loss in storage — pilot with a national retail chain
