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 elements or supposed use for shoppers. As a substitute, they function guides throughout the manufacturing course of. These marks help sensors in automated equipment to establish the place the tube ought to be lower and sealed, making certain consistency and effectivity in packaging.
The presence of those marks is essential for high-speed manufacturing traces. Automated methods depend on these visible cues to correctly fill and seal tubes, sustaining uniformity throughout all merchandise. With out these markers, the method could be considerably slower and extra liable to errors. Traditionally, these marks might 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 this time. This automation streamlines the manufacturing course of, lowering prices and making certain a constant product reaches shoppers.
