Color-Coded Toothpaste Packaging Aids

Have you ever wondered about the colored squares or rectangles at the bottom of a toothpaste? No, not the rumors that they somehow are related to the contents; they are not. Their position and the colors – green, blue, red, or black serve a crucial purpose in the manufacturing and packaging process.
Let us explain; the color-coded bits are eye marks or color marks that can be easily read by the machinery’s light beam sensors or the ‘electric eye.’ They indicate where precisely the toothpaste tubes should be cut, folded, and sealed into single units on the assembly line. Interesting fact, isn’t it?
