Gamma Irradiation Sterilization Indicator Labels
- Permanent color change after gamma dose
- Consistent response across industrial dose ranges
- Self-adhesive for packaging application
- Compatible with sterile barrier materials
- Printable for batch and process data
Permanent Visual Evidence of Gamma Irradiation Exposure
Gamma Irradiation Sterilization Indicator Labels give manufacturers and contract sterilizers a reliable visual method to confirm that products or packages have received gamma irradiation.
The indicator ink undergoes a permanent chemical color change when exposed to a sufficient radiation dose, supporting process control and quality documentation.
These labels are applied to medical device packages, pharmaceutical containers, and related sterile barrier systems before irradiation.
Vizlent selects materials that maintain adhesion and readability through the gamma process and subsequent distribution.
Applications:
Medical device manufacturing, pharmaceutical product sterilization, single-use medical kit production, contract irradiation services, laboratory equipment processing, and sterile packaging validation programs.
Specifications
Gamma irradiation sterilization indicator labels should be specified for dose response characteristics, clarity of permanent color transition, adhesive performance on packaging substrates, and stability after irradiation and handling.
