Everything you need to know about metal detectable plasters

With the paramount importance of hygiene in the food industry, metal detectable plasters have become a vital part of any first aid repertoire. Any employee working within the food manufacturing industry suffering from an injury needs to ensure that the injury is treated and secured hygienically, not just for themselves but for the integrity of the food they are working with.

The advantage of metal detectable plasters is that they can still be detected even if a contaminated food product makes it through other detection processes unseen. Most detectable plasters in the food industry are coloured blue as this is a conspicuous colour which is generally not present in most foodstuffs, allowing it to be easily spotted visually. However, there are different kinds of metal detectable plasters which are appropriate for different situations. Continue reading below to learn everything you need to know about metal detectable plasters.

Metal detection process

Most food manufacturers will conduct metal detection scans on their food products in order to detect any unwanted materials within the product. However, not all metal detector systems are identical and are capable of picking up different kinds of metal, so you need to know what kind of detector and plaster you will need. 

Non-ferrous material

Where food products or its packaging do not contain any kind of metal, then standard metal detectors capable of detecting ferrous and non-ferrous detectors are ideal as you will be able to use metal detectable plasters which contain an aluminium strip. These kinds of plasters are the most commonly found metal detectable plasters such as the Klipspringer Aeroplast plasters which are noted as some of the finest available on the market. However, if aluminium packaging is used for food products these kinds of plasters will not be suitable.

X-Ray scanning

An alternative to metal detectors is to use x-ray technology instead as a method of producing safe food products. This is an ideal solution in manufacturing environments where there are various potential contaminants present such as glass. The Klipspringer Coverplast detectable plasters are suited for X-ray machines as they contain tungsten filaments which can be picked up by X-ray scans. 

Non-ferrous and X-ray detection

For added security and peace of mind, the Klipspringer Coverplast range of detectable plasters are capable of being detected by both non-ferrous detectors and X-ray machines. By implementing a dual detection process, companies will be able to detect more foreign materials within products than before.

Ferrous or stainless steel

Because many food products will contain metal such as aluminium packaging, some metal detectors are utilized to pick up only certain kinds of metals like iron or stainless steel. Although this methodology will be able to isolate incidents where iron or stainless steel is present, it will neglect to pick up other kinds of metal, such as non-ferrous as the machine is specialised to detect only particular metals.

Optimise your detectors

Metal detection in the food industry is not just a simple process of putting a product through a machine. There are a wide variety of factors which can influence the detectability of metals such as the position/orientation of metal and shape. If you make any changes to your food production process, you will also need to reflect these changes within your detection systems.
