FREQUENTLY ASKED QUESTIONS

We know that not everyone will be an expert in detectable technology - That's what we're here for!

 

With that in mind, please find below some answers to questions you may have regarding our various processes and terminologies. 

 

The ability to be detected and rejected by an industrial metal detection system, designed to sense varying degrees of ferromagnetic, non-ferromagnetic and non-magnetic metals.

Any applications where there is a risk of small fragments entering the production flow e.g. tags, straps, pallets, seals etc.  These fragments need to be detected to minimise the risk of them entering the consumer chain.

WHAT ARE DETECTABLE PLASTICS USED FOR?

The ability to absorb sufficient X-rays such that there is a noticeable difference in intensity (grey value) in the final image between a foreign body and food product.

WHAT DOES X-RAY DETECTABLE MEAN?

WHAT DOES METAL DETECTABLE MEAN?

ARE STANDARD, UNFILLED PLASTICS & RUBBERS DETECTABLE BY METAL/X-RAY TECHNIQUES?

Unfilled plastics and rubbers will not generate a response from a metal detector and will pass undetected.  Depending upon material density and thickness as well as food product type and thickness, unfilled plastics and rubbers can potentially be detected by an X-ray system, but this level of detectability is far from optimised.  Detection levels and hence product safety on a food processing line can be significantly improved upon.

HOW ARE STANDARD PLASTICS & RUBBERS MADE DETECTABLE?

Special additives are compounded/mixed into the base materials at controlled levels to optimise either metal detection, X-ray detection or a combination of both.

DO DETECTABLE ADDITIVES AFFECT MECHANICAL PROPERTIES & PIGMENTING POTENTIAL OF FINAL MATERIALS?

Any addition into a plastic/rubber will have an effect on mechanical properties, however, this can be controlled via the design of the final compound and the quality of the additives used.  Some additives commonly utilised for metal detection will impart a very dark shade to the final material and make pigmenting difficult.  We are also able to utilise additives which are far brighter in appearance and allow pigmenting of final materials to bold and bright colours.
