Based in Auckland city of New Zealand, TNA New Zealand Ltd was established in 1982. The company provides specialised packaging solutions to the snack food industry and then expanded into other food production areas. Various packaging systems, packaging equipment and packaging solution are offered to clients.
TNA New Zealand also provides metal detectors with Cancellation Field (ICF) technology, which eliminates all interference from nearby metal structures. This technology is designed to provide maximum frequency and stability even in reduced spaces.
Various features offered by these metal detectors from TNA New Zealand Ltd include advanced coil design providing enhanced sensitivity, operation at multiple frequencies to automatically accommodate variations in product specifications, walkie-talkie safe, high reliability and patented Zero Metal Free Zone (ZMFZ) Technology.
The Cancellation Field technology protects these detectors from signals that are created by metallised film, aluminium foil or recycled chipboard packaging. Safeline’s digital technology is used to ensure better performance by metal detection devices in the packaging and processing industry. These devices offer protection from ferrous and non-ferrous contamination, even from the most difficult to detect stainless steel fragments.
