Ink pens are such a common everyday item, and most people never take into consideration that there can be different types of pens for different purposes. People who work in foodservice should not be using any ordinary pens. There are actually pens that are specifically designed to be used in foodservice and have certain qualities for the purpose. Metal-detectable food pens are available and are safe to use. Here is a look at how these pens differ from ordinary pens.
The pens are filled with food-safe ink
Not all inks are safe for use around food or on food packaging. Some inks are actually alcohol-based, which means they can eat through certain types of materials. The ink inside of a metal-detectable food pen is safe for use on the packaging or around the foods that you have in the area without causing any concern.
The pens are detectable with a magnet
Using an ink pen in a food-service setting means having to be especially careful about not leaving the pen inside of food. Most pens would be hard to spot or notice if they were dropped into food. However, these pens are designed with metal casings that are ferrous, which means they are easily picked up by a magnet and easily visible through x-ray. Furthermore, the pens have a bright exterior appearance so they are highly noticeable with the naked eye.
The pens will write in varying temperatures
The metal-detectable food pen will not freeze up or stop working if you are using it in a cooler or freezer. With an ordinary pen, the ink will harden on the surface of the nib before it can be released on what you are writing on. In foodservice settings, the writing environment may not always be room temperature, so a specially designed pen must be used.
The pens can write through oils and grease
The pens that are used for this purpose have a type of ink inside that is specifically created to write in all kinds of situations, but the ink is also created so that it can write through oils and grease. Most ink pens are designed with a rollerball, which means the ball will pick up oils and grease as you write across surfaces with these contaminants and stop functioning. Food pens have a different design that allows the ink to continually flow through the nib.
