Using gamma irradiation to sterilise food is a problem for processors wishing to embrace RFID technology because gamma rays cause the tags to malfunction.
GammaTag, which is both readable and writable, overcomes the problem by being completely resistant to irradiation, its manufacturer claims.
Using the GammaTag, processors and producers can now tag products at the beginning of the supply chain, rather than having to make the decision to attach an RFID tag after irradiation is complete, or not at all.
AdvantaPure chief executive office, Ken Baker said: "It simplifies sterilization because a complete, single-use process system may be gamma radiation sterilized as a unit."
The GammaTag is writable as well readable, enabling data to be written directly on the tag, unlike read-only bar code labels or tags, the company claims.
A handheld tag reader using process equipment tracking software, known as PET, allows access to the current status of products on location. Operators can aim the reader towards the tag to recall information or to write new data to the tag.
GammaTag easily attaches to components such as sample and production bags, tanks, filters, manifolds, tubing and hose, storage vessels, and to complete single-use systems, AdvantaPure claims.
Several attachment methods, such as silicone tape, watchband style holders, pouches, and lamination are available.
AdvantaPure claims the GammaTag can withstand gamma radiation up to 45 kilograys and temperatures from -20C (-4F) to 85C (185F).
