Meaning of The “Secret” Colour Codes On Toothpaste Tubes


There are different colours as you might have seen. There are red, blue, red and black colours and they are nothing but eye marks. As someone who has worked in a multinational production factory — packaging development to be precise — I know that these are eye marks.

So what are Eye Marks on Toothpaste packaging tubes?

According to bestpkg,  eye mark is a machine-recognizable mark, printed on web-fed packaging materials. The eye – mark is the reference point from which the machine will register other operations such as further decorations, heat sealing, or package cut-off.

In clearer terms, when products already filled in tubes or sachets are to be sealed, the eye marks are there to tell the machine the point at which the particular tube or sachet ends. The machine, depending on what it needs to do would then either seal the package and/or cut it off that point.

If you look other products like creams, milk sachets and beverages packed in sachets, you might just see them there too.
