Purpose: The primary function of these lines is to assist automated packaging machines during the manufacturing process. They are used as sensors to help machines accurately detect where to cut, fold, or seal the tube of toothpaste.
How It Works: When the toothpaste tube is manufactured, the eye mark serves as a visual cue to the machinery that processes and packages the tubes. The line is placed in a specific spot, and the machinery uses it to line up or adjust the tube for packaging, ensuring consistency and preventing errors.
What You Can Expect: The color of the line can vary, but it doesn’t change the toothpaste’s formulation. Whether it’s green, blue, red, or black, the line only has a functional purpose in the production line.
2. What the Color Means (If Anything)
The Myth: Over the years, a rumor has circulated suggesting that the color of the line indicates the ingredients of the toothpaste, with each color representing a different type of formulation (e.g., green for natural toothpaste, blue for regular, red for medicinal, and black for chemical-based).
The Truth: This is not true. The color of the line is not indicative of the product’s composition. It’s purely a production-related marking, unrelated to the toothpaste’s ingredients or benefits.
3. The Role of Automation in Toothpaste Manufacturing
Why It’s Important: In the mass production of toothpaste, efficiency and precision are key. Automated machines are responsible for filling, sealing, and packaging the toothpaste tubes, and the eye mark ensures that each tube is properly aligned and processed.
How Automation Works: Once the paste is filled into the tube, the machines rely on these marks to make sure the tube is placed correctly in the sealing station, where the cap is put on. The mark guides the machine to align the tube for precise cutting and sealing.
