Codes disappearing after the pressure cooker? Try this CIJ heat-resistant ink!
Food packaging business owners know the pain: production dates perfectly printed, but after going through the sterilization cooker—either blurred into a mess or completely gone. The cost of reworking entire batches? You know it better than anyone.
This video demonstrates a CIJ heat-resistant anti-migration ink specially developed for retort processes. After coding on a PE food bag and cooking it in a pressure cooker at 125℃ for 40 minutes—the code remained clear as new, edges sharp, with no diffusion. Then came finger rubbing—multiple times—the code stayed firmly in place.
What does this mean for you? It means your product's traceability information remains clearly readable from production line to consumer hands, with no quality issues caused by sterilization.
Ideal for retort pouches, vacuum packaging, boiled products, ready meals, and more. If coding stability gives you headaches, this ink is worth knowing.
