GN 237.1 Hinges Detectable, FDA Compliant Plastic

Visually detectable standard parts are made of blue plastic.
The blue color makes them especially visible to the human eye and, perhaps more importantly, to optical monitoring systems. Especially in milk and meat products, but also in most other areas of food production, blue colors are rarely encountered and therefore stand out well.
Complete standard parts or only pieces of them that mistakenly end up in the food production can then be easily and reliably detected. In addition, contaminants and residues of food on standard parts and operating elements are also easier to identify thanks to the color contrast.
All visually detectable plastic standard parts are made of FDA compliant plastic granulate as per FDA CFR.21 and EU 10/2011 and can therefore be used safely in contact with food and in pharmaceutical production.

Metal detectable standard parts are made of blue plastics that contain additives such as iron oxide.
As a result, they are detected by metal detectors as of a particle volume of 0.125 cm³, meaning that even hidden plastic chips can be detected. The blue color also improves visual detectability. It is always important to calibrate the metal detector since products at risk of contamination and the moisture they contain can influence the detection performance.
Also the metal detectable plastic standard parts are also made of FDA compliant plastic granulate as per FDA CFR.21 and EU 10/2011 and can therefore be used safely in contact with food and in pharmaceutical production.
