A novel material has recently been developed that could help food and pharmaceutical manufacturers comply with new regulations for food-contact use.
A key feature of products manufactured from this material is that fragments are detected and rejected by standard in-process metal detection equipment.
Known as Detectamet, these products are available from Autopac Systems , and are specially formulated, non-toxic, non-fibrous grade of polypropylene. This has a metal-based additive so that fragments as small as a 2mm cube (weighing 0.01g) can be detected and rejected, depending on the metal detection equipment used and its operating parameters.
The high-impact material, described as 'shatterproof and virtually unbreakable', helps to reduce the risk of any fragments entering the food or pharmaceutical product.
The finished articles are approved for direct food contact under EU Directive 90/128/EEC rules from the FDA (the USA Food and Drug Administration).
Detectamet products are available in red, green, yellow and the standard blue.
The most popular product developed so far is Detectamet pens. These are available as a stick design or retractable, with a choice of four colours for the pen and three colours of ink.
Clips are reinforced to reduce the chance of them becoming detached and the stick pen can be supplied without a clip if preferred.
