Toothpaste incorporates color-coded squares or stripes, usually positioned on the backside of the tube. These markings, typically known as “eye marks,” should not associated to the toothpaste’s elements or supposed use for shoppers. As an alternative, they function guides in the course of the manufacturing course of. These marks help sensors in automated equipment to establish the place the tube ought to be minimize 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 could have been totally different shapes or perhaps a easy black bar. As know-how superior, so did the precision and complexity of those markings, evolving into the coloured squares or stripes generally seen at present. This automation streamlines the manufacturing course of, decreasing prices and making certain a constant product reaches shoppers.
