Toothpaste incorporates color-coded squares or stripes, typically positioned on the backside of the tube. These markings, typically known as “eye marks,” are usually not associated to the toothpaste’s components or supposed use for shoppers. As a substitute, they function guides in the course of the manufacturing course of. These marks help sensors in automated equipment to determine the place the tube needs to be lower and sealed, making certain consistency and effectivity in packaging.
The presence of those marks is essential for high-speed manufacturing strains. Automated techniques depend on these visible cues to correctly fill and seal tubes, sustaining uniformity throughout all merchandise. With out these markers, the method can be considerably slower and extra susceptible to errors. Traditionally, these marks might have been completely different shapes or perhaps a easy black bar. As expertise superior, so did the precision and complexity of those markings, evolving into the coloured squares or stripes generally seen in the present day. This automation streamlines the manufacturing course of, decreasing prices and making certain a constant product reaches shoppers.
