Rogue pieces of metal in finished products continue to be an issue in the food industry. Although detection equipment is now widely used, good manufacturing practices are applied, the number of incidents getting through to the consumer is still too high.
In a report of metal frequently found in food, metal staples are fourth on the list. This is a solvable challenge. Specifications for ingredient packaging can prohibit the use of staples replaceable with alternative fastenings. The bigger challenge is the control of staples used in papers.
The simple solution is to make the food processing areas into staple free zones. No staples are allowed within the food processing area. However, unstapled essential documents coming into or going out of these areas can be a challenge. Without any fastening the instructions, records and traceability information could become loose and mislaid.
Detectamet have resolved the problems of loose sheets with their stapleless staplers. These simple machines mechanically cut and push a small tongue of paper through the sheets and into a slit so that the papers are securely stitched together. The result is no bits of metal and no loose pieces of paper.
